LAS VEGAS – In the beginning, the arena looked like a vacant warehouse. The Mandalay Bay Events Center felt empty. It didn’t stay that way.

A crowd began to gather, maybe to escape the recession, or the desert heat, or the Floyd Mayweather-Manny Pacquiao talks. There’s a lot to run from these days. But a good main event isn’t among them. Juan Manuel Marquez’ unanimous decision over Juan Diaz Saturday night wasn’t one of the best, not even as a rematch.

But it was an attraction in a year without many. Or any. It also was a good example of a fan base hungry for a real fight instead of just talk about one that has yet to happen and perhaps never will.

“If I never hear another word about whether Pacquiao will fight Mayweather, that’s fine with me,’’ said Rudy Perez, a Los Angeles fan who was one of 8,383 who began to fill the Mandalay Bay arena not long before opening bell for the rematch of Marquez’ stoppage of Diaz in the 2009 Fight of the Year. “I just wanted to see a couple of good fighters, good guys, really fight. I’m so sick of all that bull.’’

After his one-sided victory over Diaz, Marquez couldn’t resist talking about Pacquiao. He still wants a third shot at the Filipino Congressman, who has quit talking about Mayweather and apparently has an agreement to fight Antonio Margarito on Nov. 13.

“Everybody wants that trilogy,’’ said Marquez, who lobbied to keep himself in line for rich shot at Pacquiao if a licensing problem in the United States or some other issue knocks Margarito out of the November date. “It’s the one fight I want.’’

Perez is skeptical that Marquez will ever get that opportunity. So, too, is Golden Boy Promotions, the Oscar De La Hoya company that promotes the Mexican lightweight champion. In two fights, Marquez has been more of threat to Pacquiao than anybody since Erik Morales beat the Filipino in their first bout.

“Pacquiao should fight him,’’ Perez said. “But he won’t. No way that happens.’’

The good news is that Marquez probably will fight somebody as soon as he can. He’ll be there in the ring when there is only talk, rumors and denials on message boards.

LAS VEGAS – A trip to the hospital is no victory.

But that’s about all Jean Paul Mendy won in a scary moment Saturday night against Sakio Bika before the Juan Diaz-Juan Manuel Marquez rematch at Mandalay Bay.

Mendy was hospitalized for tests and observation after Bika was disqualified for hitting him while he was down on one knee 79 seconds after the opening bell of a super-middleweight bout.

“He put his life on the line,’’ Michael Bazan of the Mendy promotional team said.

Mendy was face down for several seconds after Bika threw an uppercut that landed like a baseball bat. Mendy never saw it coming. He was on one knee, dazed, after he had been rocked by an overhand right from Bika.

Mendy, a stationary target, was looking down at the canvas when Bika wound up and delivered the uppercut. Mendy, declared the victor by disqualification, had to be helped onto a stool.

“I’m really disappointed,’’ Bika said through a member of the publicity staff for Golden Boy Promotions. “I was very excited. I didn’t see him go to a knee.’’

It looked as if Bika would win easily in a 12-round eliminator for a shot at the International Boxing Federation title held by Lucian Bute of Montreal.

“We’re happy at the official call,’’ Gabriel Gaide, also of Mendy’s promotional team, said. “But I don’t want him winning that way. Jean Paul came to fight the right way.’’

Mendy didn’t come for the money. His purse was $12,000, according to Bazan, who said most of that went for expenses. Bazan said Mendy was fighting only for an opportunity that didn’t include a doctor’s bill.
No Maidana for Ortiz

Surfing has taught junior-welterweight Victor Ortiz something about boxing. Fights are like waves. There’s always another one.

Ortiz, a surfer when not in the gym, expressed disappointment Saturday at not getting a rematch against Marcos Maidana on Sept. 18 on the Shane Mosley-Sergio Mora card at Staples Center in Los Angeles.

But Ortiz — who has boxing gloves and his nickname, Vicious, inscribed on to his surfboard — was already looking forward, toward the horizon, for another opportunity. Maidana is gone, but it looks as if Vivian Harris will be there. Golden Boy Promotions CEO Richard Schaefer said Harris, a former World Boxing Council champion

“Sept. 18 was supposed be about a fight with Maidana,’’ Ortiz said at Mandalay Bay before Diaz-Marquez. “He turned it down.’’

Golden Boy President Oscar De La Hoya said Ortiz was anxious for some redemption in a rematch with Maidana, who scored a stunning 6th-round stoppage of Ortiz in 2009.

“I know the truth and Victor knows it too,’’ said De La Hoya, who also introduced Mosley, Mora, and emerging Mexican star Saul “Canelo” Alvarez. “He wants to redeem himself.’’

But Ortiz talked as if he only wants to continue his career, which has proceeded with three successive victories after Maidana. Questions about his will have lingered since the loss. Some in the media said Ortiz quit in the fight and that perhaps it’s time to leave the ring for the beach.

“Why retire?’’ said Ortiz, who promises that one loss didn’t wipe out the potential he displayed a few years ago. “I’m only 23.’’
NOTES, QUOTES

· Alvarez, a Guadalajara welterweight called the Mexican James Dean by Schaefer, is expected to face former WBC champ Carlos Baldomir on the Mosley-Mora undercard, which is being marketed as a celebration of the 200-year anniversary of the Mexican Revolution.

· WBC light-heavyweight champion Chad Dawson also met with the media Saturday to talk about his Aug. 14 against Jean Pascal on Pascal’s home ice in Montreal. “It’s my coming out party,’’ Dawson said of his appearance on HBO and an expected capacity crowd at Montreal’s Bell Centre.

· And Arizona’s tough immigration law continues to be a hot talking point among Mexican and Mexican-American boxers. De La Hoya told 15rounds.com Wednesday that he saw “racism” in the state’s controversial law, SB 1070. Mora wasn’t asked about the law at Saturday’s news conference. But he ripped it anyway. “Lots of ignorant laws are being passed in Arizona,’’ Mora said. “There’s a lot of bigotry and latent racism being expressed down there.’’

LAS VEGAS – It was entertaining as a one-sided fight could be, but finally, “The Rematch” was a one-sided fight. Blame it on Marquez’s class – the ageless type.

Saturday night at the Mandalay Bay Events Center, in a rematch of 2009’s Fight of the Year, Mexico City’s Juan Manuel Marquez (51-5-1, 37 KOs) and Houston’s Juan Diaz (35-4, 17 KOs) squared up to determine the lineal lightweight champion of the world. Twelve rounds later, it was the same guy as it was when the night began, with Marquez winning by unanimous decision scores of 116-112, 118-110 and 117-111.

The 15rounds.com scorecard concurred, scoring it 118-110 for Marquez.

Diaz’s strategy, to box and keep his weight from falling over his front foot, was a sound one for survival. But starting in round 1, and with only a brief exception in rounds 2 and 3, it was not a strategy that would ever bring him victory.

For his part, Marquez was the same master craftsman he has always been, riddling Diaz with left uppercut-right cross-left uppercut combinations whenever the younger man’s enthusiasm brought him within range. The rest of the time, Diaz was safe, but he wasn’t in the fight.

Afterwards, Diaz hinted at the possibility of his retirement, saying he still wasn’t sure about his future and thanking his hometown of Houston for its undying support.

Marquez, meanwhile, addressed the possibility of a rubber match with pound-for-pound champion Manny Pacquiao, after his victory.

“I think the third fight with Pacquiao is the one the aficionados want,” Marquez said. “And it’s the best thing for the fans.”

Class tells: Pirog ruins Jacobs
Golden Boy Promotions’ eye for talent has been questioned often since its inception. What Russian Dmitry Pirog did to Golden Boy prospect Daniel “Golden Child” Jacobs in the co-main event of “The Rematch” will make such questions all the more prevalent.

Pirog (17-0, 14 KOs) outclassed Jacobs (20-1, 17 KOs) in each round, using fundamental boxing to solve the speedy Brooklynite, before catching him flush with a perfect right cross, knocking Jacobs out cold at 0:57 of the fifth round to become the WBO middleweight champion of the world.

After a fairly even opening stanza, round 2 began with Pirog marching forward behind a right cross and extremely efficient footwork, entirely neutralizing Jacobs’ reflexes. Then Jacobs wisely began the third on his bicycle, circling away from Pirog, fighting part of the round as a southpaw and regaining his composure. Round four, too, passed in a somewhat even fashion.

Pirog came out in the fifth, however, backed Jacobs to the ropes and waited for him to start a tentative punch. At that moment, Pirog stepped fully into a right cross that landed on Jacobs’ chin and dropped him to the blue mat in a pile. Referee Robert Byrd wisely forwent his 10-count, waving an immediate conclusion to the fight.

Guerrero brushes away “Cepillo”

Boxing may never know Joel Casamayor’s true age, but Saturday it learned how old he now is: Too old.

In a junior welterweight scrap some in Mandalay Bay’s Events Center hoped would be competitive, California’s Robert “The Ghost” Guerrero (27-1-1, 18 KOs) easily decisioned Cuban Joel “El Cepillo” Casamayor (37-5-1, 22 KOs) by lopsided unanimous scores of 98-89, 98-89 and 97-90.

Down in each of the match’s first two rounds and penalized a point for holding, the previously resilient Casamayor looked old and spent, Saturday, as Guerrero hurt him with every landed left hand. In round 2, a Guerrero left cross even stunned Casamayor to the point of dropping both gloves and looking around in disbelief before rallying to wrap his arms round Guerrero’s trunks.

Never a strict adherent to the Queensbury rules, Casamayor looked particularly sad in his opening six minutes against Guerrero, when he was reduced to fouling to survive rather than win.

After such a shaky start, though, Casamayor, whose chin has never been doubted, found enough of his stride to give Guerrero quality rounds. Still, a Guerrero left hand or two seemed to buckle Casamayor’s old knees in almost every round.

But as the fight progressed, and Casamayor threw more punches, Guerrero began to holster his left hand, gradually sapping the match of its emotion. By the ninth round, a few vocal fans began to boo the action in the ring while the large majority of the Events Center crowd expressed its displeasure with abject silence.

The final stanza, though, saw Guerrero over-commit to a left hand and impale himself on Casamayor’s outstretched right glove. But the suspense passed quickly when Guerrero rose and boxed to a comfortable victory.

Linares plays bus driver, takes Juarez to school

Venezuelan Jorge Linares literally towered over Houston’s Rocky Juarez at Friday’s weigh-in. Saturday night, Linares towered over him figuratively too.

In the first fight of “The Rematch’s” pay-per-view telecast, Linares (29-1, 18 KOs) easily decisioned Juarez (28-7-1, 20 KOs) over 10 one-sided rounds to win the WBA’s vacant lightweight title by unanimous scores of 99-90, 97-92 and 99-90.

The fight began as Juarez fights always do, with Juarez doggedly chasing his opponent, eating punches and unable to let his own hands go. Linares, who would look nimble in the ring with anyone, looked positively balletic across from the heavy-footed Juarez. Snapping jabs and dancing away, Linares gave Juarez a boxing lesson in the fight’s first four rounds.

Towards the end of round 5, Linares landed one of many left uppercuts, and this one caused Juarez to stumble backwards and drop to the blue mat, a place one rarely finds him. Unable to hurt Linares and now worried that Linares might hurt him, Juarez, who’s hesitant even when he’s winning, began trading two Linares uppercuts for his every landed jab – a formula destined to fail.

What few vocal fans there were gave a number of halfhearted “Rocky, Rocky” chants as the fight progressed, and Juarez’s eyes continued to close, but the arena was otherwise silent enough for the bell to cause echoes at the end of each round.

The final round saw most of the fight’s sustained action, but those three minutes did not feature nearly enough pressure from Juarez to undo the 27 minutes that preceded them. The problem for Juarez, finally, is not just that he is now 0-6 in world title fights. It’s that he’s losing by larger margins in his every subsequent challenge.

Undercard

It was a case of dog attacks man in “The Rematch’s” final off-television match, as undefeated junior welterweight Los Angeleno Frankie “The Pit Bull” Gomez (5-0, 5 KOs) went through Minnesota’s Ronald Peterson (2-3, 2 KOs) without a modicum of resistance. A Gomez left hook to Peterson’s liver ended the match at 2:14 of round 1, when Peterson chose not to continue.

The fourth match on the untelevised undercard might well have been its best, as unheralded Mexican lightweight Juan Manuel Montiel (6-3-1, 1 KO) swapped blows and taunts with Nevadan Mike Peralta (4-6, 1 KO) in a well-matched six-round bout, which Montiel won by unanimous scores of 58-55, 60-53 and 58-55.

Despite spitting blood for half the fight and appearing fatigued throughout, Peralta nevertheless entertained the local crowd with his heart and will. Finally, though, Montiel had too much class, and the judges did not see the fight competitive as fans did.

The night’s third bout came to a rapid and ugly end when Australian Sakio Bika (28-4-2, 19 KOs) fouled undefeated and unarmed Frenchman Jean Paul Mendy (29-0-1, 16 KOs) at 1:19 of the first round of their IBF super middleweight eliminator, losing by disqualification and bringing some well-deserved hostility from the desert crowd.

In a maneuver disappointingly reminiscent of a different super middleweight – Arthur Abraham and his right hand to a kneeling Andre Dirrell in March – Bika knocked Mendy to the canvas and then stepped forward and fired a point-blank right uppercut at the defenseless Frenchman. Mendy, who had almost no power to speak of while upright, tilted forward and landed on his own forehead. Referee Joe Cortez called an immediate end to the match.

Mendy was later able to walk from ringside unassisted.

At Friday’s weigh-in, ESPN commentator (and cruiserweight contender) BJ Flores said the man to watch on Saturday’s undercard was a Brit by the name of George Groves. Flores was right. Accompanied to ringside by heavyweight titlist David Haye and favoring a left hook-right cross combination, Groves (10-0, 8 KOs) chopped away at Mexican Afredo Contreras (11-8-1, 5 KOs) until a somewhat early intervention by referee Russell Mora halted the match at 0:48 of the sixth round.

While Contreras did not appear to be in any trouble, and never went down, Groves, for his part, appeared to be committing fully to each of the right crosses with which he tagged Contreras with increasing frequency.

Before that, “The Rematch” got off to a quick and violent start Saturday afternoon as Maryland heavyweight Seth “Mayhem” Mitchell (18-0-1, 12 KOs) went directly through overmatched Philadelphian Derek Bryant (20-6-1, 17 KOs), stopping him at 1:45 of the first round.

After firing a succession of left hooks to Bryant’s body, Mitchell went upstairs with lefts and rights to the head and continued his assault till referee Kenny Bayless had seen enough.

The opening bell rang on a sparse Events Center crowd at 2:40 PM local time.

“How did you go bankrupt?” Bill asked. “Two ways,” Mike said. “Gradually and then suddenly.” – Ernest Hemingway, “The Sun Also Rises”

And so it is with a prizefighter’s energy and legs. He begins a championship fight doing as he planned. He loses strength at predictable intervals, familiar intervals, intervals commensurate with his opponent’s. Then suddenly he finds himself weak and discomfited.

So go championship prizefights. So go champions’ careers.

That race, right there, who gets from gradual bankruptcy to sudden first, will determine the loser of “The Rematch” at Mandalay Bay. That is what they’re calling the second fight between Ring magazine lightweight champion Juan Manuel Marquez and Juan Diaz, to remind us Marquez-Diaz I was 2009’s Fight of the Year.

Think of this fight as a race – Marquez’s legs against Diaz’s energy – where the loser will be lightweight champion of the world. The gradual bankruptcy of Marquez’s legs can be measured in years. The gradual bankruptcy of Diaz’s energy will be measured in minutes. And then, suddenly, one of those will be measured in instants.

Something like that happened when Marquez and Diaz fought the first time, in Diaz’s hometown of Houston, 17 months ago. Few of us knew it at the time, and no one knew it at ringside. The closest anyone came, probably, was Marquez’s trainer Nacho Beristain. He couldn’t be sure his fighter’s legs wouldn’t wilt under the heat and humidity of Diaz’s relentlessness, but he knew his fighter’s spirit was implacable and courage unquestionable. And he knew he wasn’t going to stop the fight regardless.

“Juan is not fragile.” That’s how Beristain explained it an hour after his fighter knocked-out Diaz in round 9. Beristain was certain to a point of dismissive about his charge’s fortitude in those opening rounds when Marquez’s mouthpiece was visible for two of every three minutes. He was amused by an inquiry about his own state of mind when Marquez was bullied to the ropes by the “Baby Bull” time and again. No, Beristain wanted it understood, he couldn’t have been less preoccupied by what he saw.

He was about the only one. Diaz appeared to have his way with Marquez in the fight’s opening half. He had me fooled; I scored the opening six rounds 4-1-1 for Diaz. And after round 6, when an esteemed fight scribe leaned over and said Marquez wouldn’t get out of the eighth, I nodded.

But by then Marquez had begun to do something we mistook for a ruined spirit. He’d begun to pivot away from Diaz rather than fighting Diaz off him. It was uncharacteristic of Marquez. He was the more accurate puncher in every minute, of course, but he was also the smaller and older man. His sudden change of strategy appeared, if not a surrender, certainly the opening sentence of an unfavorable treaty: You let me finish on my feet, and I’ll stay out of your way.

What had really happened, though, was different. Marquez had seen the first cracks in Diaz’s relentless spirit. Those cracks lent Marquez time enough to take a look around. And when he did, he realized he was not being outmaneuvered but cowed. Diaz was not pinning him to the ropes with superior footwork but merely corralling him with activity. And that reminded Marquez he hadn’t survived the rings of Mexico City without discouraging a few relentless left-hookers.

That was when the 35 year-old switched from brawler to dancer to assassin. He pivoted away from Diaz and struck the younger man now searching for an abruptly elusive target. He stopped trying to break Diaz on Diaz’s terms and began to stretch him on the rack of fundamental boxing: straight punches hurt more than crooked ones.

Diaz must have been surprised. He had, after all, faced larger, tougher men at lightweight, wearing each down with his knuckles, the cuffs of his gloves, the commitment of his blows, his self-belief. Here was a smaller man whose temples he’d assaulted with 20 minutes of hooks. Here was a lighter man whose neck he’d whiplashed with battering-ram jabs. Here was a boxer, a craftsman, whose sensibilities he’d surely offended.

And now he pivots away on fresh legs? And now my knees are suddenly hollow?

But Diaz did the right thing when bankruptcy visited him suddenly: He pressed forward. He was either about to fool Marquez, or bring a mercifully quick conclusion to his evening. And Marquez wasn’t fooled.

Marquez is hard to fool. Ask Floyd Mayweather. Mayweather apologists – a species the great man himself is rendering extinct – may still insist that after knocking Marquez down in the second round of their mismatched fight, Mayweather didn’t press because he “needed rounds.” But that’s inane. Rounds to do what, sharpen his potshots on a man 15 pounds smaller? Mayweather could get better work in the gym.

No, Mayweather didn’t press Marquez because, 15 pounds or 50, you don’t stop Marquez without making a slow tour of hell to get there. That’s not Mayweather’s style. Even when Marquez was hurt, especially when he was hurt, he fought back with harshest intentions. Mayweather was against the best counterpuncher he’d ever faced, and he backed off. Mayweather couldn’t stop Marquez in 100 rounds of trying.

Diaz, on the other hand, hasn’t Mayweather’s luxury of reflexes or class. He will have to go straight at Marquez because it affords him the best chance of making Marquez’s now-36-year-old legs go bankrupt. And in so doing, Diaz will afford Marquez a chance to take Diaz’s energy to bankruptcy, by pivoting away earlier and finishing Diaz quicker than the first time.

Marquez has been losing his legs gradually since he moved from featherweight. So is it possible they could go bankrupt suddenly on Saturday? Yes. Does Diaz have the style to cause it? Yes. Does Diaz have the energy to do it? I don’t think so.

I’ll take Marquez: KO-7.

The Juan Manuel Marquez-Juan Diaz sequel to the 2009 Fight of the Year on July 31 at Las Vegas’ Mandalay Bay has a simple marketing label: The Rematch. Golden Boy Promotions President Oscar De La Hoya and CEO Richard Schaefer also could have called it The Relief.

Let’s just say that Marquez-Diaz II and its compelling undercard are a timely refuge from talks – or whatever they were – for Manny Pacquiao-Floyd Mayweather Jr. A couple of testaments, old and new, could be filled with all that has been said, written, rumored, alleged and denied about a fight that has yet to happen and perhaps never will.

Attention on Pacquiao-Mayweather is sucking the wind out of a sport full of good stories, of which there are many on the Diaz-Marquez card. There is Robert Guerrero, who faces Joel Casamayor. He fights for his wife, Casey, who has fought leukemia and knocked the cancer into remission.

There’s Diaz, an aspiring lawyer and proud son of Mexican immigrants who is fighting to keep his career alive while he argues for rights that he believes are under assault in the wake of Arizona’s tough new immigration law.

There’s Rocky Juarez, who faces Jorge Linares. Juarez, who is 0-5-1 in world title fights, was robbed at the 2000 Olympics of a gold medal and left with silver that he says reflects a career full of frustration. Yet, he is still pursuing a world title, still trying turn silver into gold.

Guerrero, Diaz and Juarez are just a few of the stories that once put a gritty face on a sport that, in large part, has been about comebacks, second chances and redemption. Now, however, all of the focus appears to be on nothing, which worked on Seinfeld but won’t in boxing.

It’s been there before, following Mike Tyson to nowhere. Tyson was the train wreck that kept everybody looking only for the next accident instead of the next prospect. Tyson moved on and mixed martial arts moved in.

De La Hoya, Pacquiao and Mayweather helped boxing diversify and it began to recover. Yet, suddenly it is back at an intersection where one story, and only one, seems to matter. Who to blame? From promoters to regulators, the usual suspects are there.

But the internet, the only media that covers the sport regularly anymore, also deserves its share. Determining a good story isn’t much of a choice anymore. It’s all about numbers, hits. Plug in the right words and you’ve got a winner recognized by the Google algorithm. That means Pacquiao and Mayweather, over and over again.

The internet equation often means the media follows the mob instead of the stories. Guerrero, Diaz and Juarez offer an old-school, perhaps quaint opportunity to reverse that trend during the next week. Each has different motivations. Yet, each is confronted with a fight the looms as decisive in what they do next.

“I see this as a win-win situation,’’ Diaz said during a conference call when asked about the significance attached to chances at avenging his 2009 loss by knockout to Marquez. “This fight is going to prove to me whether I have it or I don’t. This fight right here is what’s going to take me to the top and make me the super star that I’ve been wanting to be in the lightweight division.

“But if it doesn’t happen then that means it’s not meant to be and I’ll move on to bigger and better things, which could be start from the bottom and pick up the pieces to rebuild myself up or just completely do a 360 – I mean a 180 – and just go in the opposite direction.

“This fight here, a lot of people have been mentioning to me that it’s a do-or-die fight. Well, I don’t think it is do-or-die. I think it’s win-win because either I become a world champion once again and become a super star or it opens up doors for me to do other things and focus on other aspects of my life.’’

Real-life.

For now and perhaps forever, that represents a real chance at future business, unlike Pacquiao-Mayweather, which is beginning to look like fantasy that will never be more than a video game.

According to Dan Rafael of espn.com, an intriguing IBF Super Middleweight elimination bout between undefeated Jean Paul Mendy and former world title challenger Sakio Bika has been added to the off-tv portion of the packed cardthat will feature the Lightweight title rematch of the 2009 fight of the year between Juan Manuel Marquez and Juan Diaz that will take place July 31st in Las Vegas.

The winner of Bika-Mendy will earn a mandatory shot against 168-pound titleholder Lucian Bute.

“This is truly a ‘Fight Freak’ card for the ages,” said Richard Schaefer , CEO of Golden Boy Promotions who will promote the card. “We are going all out to make July 31 a night to remember for boxing and sports fans. The addition of Bika versus Mendy is another all-action fight which supplements a card which I consider to be one of the best top to bottom boxing events in the past few years.”

Schaefer said Bika-Mendy will take place just before the HBO PPV telecast begins but that highlights of the bout would air during the broadcast. However, he said is working on having the fight, along with another undercard match featuring blue-chip junior welterweight prospect Frankie Gomez, shown live as a free preview in the hour preceding the start of the pay-per-view telecast.

“We’re trying now to secure the free window from the PPV channels,” Schaefer said. “Looking good.”

No, the upcoming rematch between Juan Manuel Marquez and Juan Diaz does not belong on pay-per-view. Two fighters whose cumulative record is 1-2 since their first match should not charge extra for a second go. And no, this fight does not belong in Las Vegas. Chilango versus Houstonian, surely, has more appropriate host cities.

There, that takes care of the disclaimer. In keeping with the sprit of this long weekend, in fact, let’s call what’s above a Preamble. Now for the salvaging.

On July 31, Marquez and Diaz will fight for Marquez’s WBA, WBO and Ring magazine lightweight titles at Mandalay Bay. It will be the first fight for Marquez since his 10-unanimous-rounds-to-none loss to Floyd Mayweather in September. It will be the first fight for Diaz since his one-sided loss to Paulie Malignaggi in December.

It will also be a rematch of 2009’s Fight of the Year. That lends the match a distinction its combatants’ recent showings cannot sully. Yes, Marquez was foolish to make the mercenary’s choice and take that high-paying fight with that high-weighing superstar. And yes, Diaz was nobly foolish to grant Yankee Fan an immediate rematch on neutral ground. But there we are.

Where we also might consider being in four Saturdays is Las Vegas. Marquez-Diaz I really was that good – especially if you were in Houston’s Toyota Center to see it.

I was in Houston 16 months ago. That’s why I’ll be in Las Vegas later this month – to honor the combatants and see if they can do it again.

A doubtful proposition. After all, there was a reason Diaz began the post-fight press conference by assuring his mother he was OK. There was a reason Marquez called-out Mayweather – aside from Manny Pacquiao’s not wanting a rubber match. It was because none of us who sat in that Toyota Center conference room hankered for Marquez-Diaz II.

The fight was excellent. Sensational, actually. But it left few questions unanswered. Act One saw Diaz apply great pressure, assaulting Marquez’s vanity with the rude force of his youth. Act Two saw Marquez change from veteran boxer to hot-blooded finisher. The fight’s arc resembled that of Margarito-Cotto, but with a more decisive ending and no later allegations of foul play. Its decisive ending also saw Marquez set a new standard in right uppercuts.

You had another chance to see that right uppercut, Friday night, when Golden Boy Promotions replayed Marquez-Diaz I in something of a Telefutura infomercial on its weekly “Solo Boxeo” program. The purpose of that 90-minute program was to promote “Marquez-Diaz 2” of course. But Golden Boy Promotions deserves credit for another thing it did, and has been doing: Easing Israel Vazquez into retirement.

For the third week in a row, Vazquez was a major part of the Telefutura broadcast. You hope he enjoys his time in front of the camera enough not to return to the ring. Looking at his face and listening to his speech gives you the impression that if a pending retirement comes in time for Izzy, it will be just barely.

But Golden Boy Promotions also has a different kind of infomercial it routinely does that is less creditable. That would be the emphasis it places on sponsors in conference calls and press conferences – ostensibly media events. This has never felt right for reasons that couldn’t quite be identified.

Until the opening part of last week’s conference call when CEO Richard Schaefer recognized Cerveza Tecate, AT&T and NCM Fathom. It sounded exactly like a Wall Street earnings call – that quarterly tradition in which an executive tells analysts why others should invest in his company.

Which is where the incongruity sets in. Golden Boy Promotions is not a publicly traded company; no one on these calls or at these press conferences is a potential investor. It’s akin to a Hollywood studio inviting critics to a movie screening and then discussing concession sales. It seems to miss the point of American journalism.

We’ve gone along with it for years as part of our advocacy for a thing Top Rank’s Todd DuBoef recently called “brand of boxing” in an interview with Thomas Hauser. We want the sport to succeed. We were ecstatic when we thought corporate sponsorships would somehow lead to mainstream interest. That hasn’t happened. Instead, these sponsorships are but another way to help millionaires get richer.

Which is fine. It’s part of the system formerly known as democratic capitalism. But it is not news, and it should not be treated as such. Journalism is not public relations.

Got it? Good. Now let me don my PR cap.

Las Vegas needs your help. No city has felt the depredating effects of the Great Recession more. It looked desperate, starving even, last November. And since then, there’s nary a report of its having improved.

Juan Manuel Marquez and Juan Diaz, too, could use your help. Both need to strike their most recent fights from folks’ memories. They promise to make a compelling match – master boxer-finisher against young volume puncher – any time they share a ring.

And the brand of boxing? It should be championed. Supporting a city that has been an important part of that brand is an admirable thing to do. But the best reason to attend Marquez-Diaz II is this: We cannot allow our sport to be held hostage by a fight unlikely to happen.

We must celebrate the fights we have and the fighters who make them. There’s no need to waste words or time on others. No need to waste them on sponsors, either.

See you in Las Vegas.

It will be a battle of former world champions according to Dan Rafael of espn.com when Joel Casamayor battles Robert Guerrero on July 31st as part of the Juan Manuel Marquez – Juan Diaz rematch undercard.

Casamayor-Guerrero, a scheduled 10-rounder at a maximum contract weight of 139 pounds, rounds out the four-fight telecast that will include Marquez-Diaz II, 2009 ESPN.com prospect of the year Daniel Jacobs facing Russia’s Dmitry Pirog for a vacant middleweight title and a lightweight bout between former two-division titlist Jorge Linares and perennial contender Rocky Juarez.

“I made a promise to the ‘Fight Freaks’ that this would be a freak card and I think I’ve delivered that,” Golden Boy CEO Richard Schaefer told ESPN.com. “I love Casamayor against Guerrero. It’s a big step up for Guerrero and a big opportunity for Casamayor. It’s one of those true crossroads fights. We have Linares-Juarez done and we have Jacobs fighting an undefeated fighter for a world title. I think the rematch of the fight of the year has become more than just that. I think it’s going to be the night of the year.”

“We are finalizing the contract, but we have an agreement by e-mail and have agreed on all the deal points,” Schaefer said.

“Joel is a veteran and he wanted a bigger fight. He wanted Khan,” manager Luis DeCubas Jr. told ESPN.com. “But if it’s not Khan, he’ll fight Guerrero. I think we’re in a different league than Guerrero. Robert is a great young fighter, but he’s never been in there with anyone like Joel. He’s real green. We’ll go through Guerrero first and then we’ll go get Khan or (junior welterweight titleholder Timothy) Bradley, or anyone else.”

“I think to have Linares back [fighting in the U.S.] and fighting a credible opponent like Rocky, I think it’s a big test for Linares, and it’s high noon for Rocky,” Schaefer said. “It’s a very interesting matchup.”

According to Dan Rafael of espn.com, Daniel Jacobs will take on Dimitry Pirog for the recently vacated WBO Middleweight crown on July 31st in Las Vegas as part of the PPV undercard that will be headlined by the rematch of the 2009 Fight of the Year between Juan Manuel Marquez and Juan Diaz.

“Whenever Al(Haymmon who is Jacobs advisor) calls me it’s usually with good news, so when he called me and he also had Richard on the line, too, I knew I was going to go crazy,” Jacobs told ESPN.com on Monday. “They gave me the word and I screamed. I was so excited. It was a really good feeling.”

They told Jacobs (20-0, 17 KOs) that he would be facing Russia’s Dmitry Pirog (16-0, 13 KOs) for a vacant title on July 31 at Mandalay Bay in Las Vegas.

“We are all done,” Schaefer said from London. “I think it’s a tremendous opportunity for Danny. He’s come along very nicely. He’s a well-spoken and charismatic fighter. He had a great amateur career and we have built him up nicely. We all feel he is ready to fight for a title. We are excited he will have the opportunity. We will see how he will do.”

“The WBO ordered negotiations since Danny and [Pirog] were the next contenders, and Artie Puello and me very quickly put a deal together,” Schaefer said. “We finalized it over the weekend.”

“I feel blessed,” said Jacobs, who is from the tough Brownsville section of Brooklyn, N.Y., that also produced former heavyweight champs Mike Tyson and Riddick Bowe. “A lot of people in my position, coming where I come from, to get an opportunity like this is one in a million.”

“I feel like I am ready for a world championship fight,” he said. “I don’t think there are too many threats out there. I think if I get this world championship come July 31, I think we’ll have more improvements to do, like getting experience and such. But if anyone has an opportunity to get a world title I don’t think anyone would decline.”

“I know they’ll call me a paper champion when I win,” Jacobs said. “But look at it from the other standpoint — anyone in my position, they wouldn’t decline it if offered. Believe me, if I had the opportunity to fight Sergio Martinez and win the title from him, I would want to do it that way. I would want to take the belt from him, but the opportunity hasn’t been presented to me. This one was. I took it.

“I’m a fighter but I am also a boxing fan as well, so you never really like paper champions. You have to make a name for yourself and then I will get respect as a legitimate world champion down the line when I do fight those other top guys. I want to be a true world champion, but this is my opportunity to start down that road.”

According to Dan Rafael of espn.com, the rematch of 2009’s fight of the year between Juan Manuel Marquez and Juan Diaz will take place July 31st in Las Vegas on Pay Per View.

Marquez-Diaz I took place in front of a wild crowd of more than 14,000 on Feb. 28, 2009, at the Toyota Center in Diaz’s hometown of Houston. It turned out to be an unforgettable fight and was named fight of the year by ESPN.com, the Boxing Writers Association of America and Ring magazine.

“These two guys are made for each other,” Golden Boy CEO Richard Schaefer said. “The first fight was fight of the year and I have no doubt the rematch will be another great fight.”

“I came back to lightweight because at welterweight I lost a lot of speed,” Marquez said.

“I know that 140 is not my weight class,” Diaz said. “It didn’t take anything away from me.”

“I am going to forget our first fight. It is like it never happened,” Marquez said. “I am going in as if this were our first meeting. A lot of people are asking me, ‘Why Juan Diaz again?’ There are two reasons. No. 1 is that he is a great fighter and deserves a rematch. No. 2, the people deserve a great fight like this.

“Our fight was the fight of the year in 2009 and it may be the fight of the year again in 2010. Finally I want to give the people a great fight, especially the Mexican people. You are all going to see two warriors who will give everything they have and leave everything in the ring.”

“I am very excited because I have two things going on in these next couple of months,” Diaz said. “I have the second biggest fight of my career. I have some career defining decisions. On June 7, I am going to take the LSAT and those logic puzzles are kicking my butt. I am excited because this is going to be a great summer for myself, for my family and for my team.

“People are saying this is going to be a must win fight for me. But I don’t see it that way. I see this as redemption. Redemption for what I was going to accomplish in 2009, but it wasn’t meant to be. Come July 31, I am going to pick up in the ninth round. I left off in the ninth round last time, and I am going to pick it up from there.”
