Saturday at London

David Haye TKO5 Dereck Chisora

Heavyweight

Records: Haye (26-2, 24 KOs); Chisora (15-4, 9 KOs)

Rafael's remarks: A year ago, after Haye's miserable non-effort against heavyweight champion Wladimir Klitschko in their unification bout and the now-famous toe injury excuse following the wipeout decision loss, Haye was the laughingstock of boxing and went into a retirement that few believed would last. To nobody's surprise, Haye, 31, returned to face British countryman Dereck Chisora, 28, in the wake of their ugly bottle-smashing brawl in February at the news conference following Chisora's decision loss to Vitali Klitschko in a title fight in Munich, Germany. The bad blood between Haye and Chisora ignited heavy interest in seeing them fight, and so with a ton of money to be made, promoter Frank Warren put the fight together. To do it, Warren had to go against the British Board of Boxing Control -- which was embarrassed by the press conference melee and refused to sanction what became an outlaw fight -- and bringing in the Luxembourg Boxing Federation to oversee the event.

All fight fans should be happy that Warren did that because it turned out to be a very entertaining fight in which Haye, the former cruiserweight champion, looked as good as he has looked since moving up to heavyweight fulltime in late 2008. Although the 210-pound Haye was giving up tremendous weight to the 247-pound Chisora, Haye was explosive with his punches and much faster. Although Chisora got in some solid shots, he mainly was trying to land an overhand right to Haye's questionable chin.

But Haye did a good job of protecting himself and also of jabbing well, landing right hands, left hooks and showing enough lateral movement to leave Chisora often swinging at air. Haye and trainer/manager Adam Booth had a perfect game plan and Haye followed it perfectly. Haye was in full command in the fifth round when he put Chisora away with two knockdowns. First it was a left-right combination that dropped Chisora out of nowhere. It was a surprise because Chisora has a reputation for having a great chin. He appeared to be clear-headed when the fight resumed, but Haye went for the knockout and moments later unleashed a five-punch combination, including a clean left hook that dropped Chisora again. Chisora made it to his feet again, but this time referee Luis Pabon did not like how he responded and called off the fight at 2 minutes, 59 seconds.

It was a terrific win for Haye, who shoved his way back into the conversation for another major fight. He wants a shot at Vitali Klitschko and started up with the trash talk after the fight. It is a fight that could happen, but not until next year since Klitschko is scheduled to fight Manuel Charr in Moscow on Sept. 8. If Klitschko beats Charr and continues fighting (no guarantee if he wins political office in Ukraine in October), a Klitschko-Haye fight is certainly possible and a major fight. Charr, by the way, showed up at the post-fight press conference to proclaim he would give Haye a shot at him after he beats Klitschko. While Haye is back in business, Chisora will need a couple of comeback wins to try to position himself for another big fight because he has now officially lost four of his last five fights, even though the spit decision loss to Robert Helenius in December in Helenius' home country of Finland was one of the worst robberies of the year. All in all, despite the controversy over the fight and reason why it happened -- the unfortunate February brawl -- the fight turned out to be very exciting and good for boxing. It was also nice to see Haye and Chisora bury their bad feelings by embracing after the fight and showing respect for each other at their post-fight news conference, where nobody got glassed.

Saturday at Las Vegas

Anthony Mundine TKO7 Bronco McKart

Middleweight

Records: Mundine (44-4, 26 KOs); McKart (54-10-1, 32 KOs)

Rafael's remarks: Mundine, 37, of Australia, a former two-time second-tier WBA super middleweight beltholder whose hateful anti-American comments following Sept. 11 made him reviled by those in the United States who had heard of him. A decade later, Mundine unfortunately made his American debut in the headline fight of a WealthTV pay-per-view card that was so filled with cliché and hyperbole it was unwatchable with the audio on. The match also wasn't worth a damn as McKart, 41, of Monroe, Mich., is well past his prime. The southpaw was once a very good boxer who held a junior middleweight belt for two months -- all the way back in 1996. But he is best known for losing decisions to Winky Wright three times in one of the most unnecessary trilogies in boxing history. So even though Mundine got the convincing stoppage victory, to hear him talk after the fight about how he had somehow proven something was laughable. In one of the more delusional interviews ever, Mundine called out for Floyd Mayweather Jr. to fight him (with spectator Floyd Mayweather Sr. in the ring after the fight). Who would ever want to see that fight? While he was at it, Mundine also called out Miguel Cotto and Saul "Canelo" Alvarez. In any event, Mundine did his business, as expected, against McKart, landing some solid combinations and taking control early, even if he did spend more time than he should have admiring his work. In the seventh round, Mundine dropped McKart three times to finish the fight. He caught him with a left hand behind the ear and sent him down face first. McKart fought back and landed a few shots, but Mundine dropped him to a knee with a right hand to the side of the head. McKart's legs were gone, so when Mundine landed an uppercut, he was all over the place and went down again as his corner was throwing in the towel, and referee Robert Byrd called it off at 2 minutes, 4 seconds. Now Mundine ought to head back to Australia and not let the door hit him on the way out.

Saturday at Culiacan, Mexico

Hernan "Tyson" Marquez W10 Fernando Lumacad

Junior bantamweight

Scores: 97-94 (twice), 95-95

Records: Marquez (34-0, 25 KOs); Lumacad (26-4-3, 11 KOs)

Rafael's remarks: Marquez, 23, of Mexico, holds a flyweight title but with talks for a mandatory defense against interim titlist Juan Carlos Reveco hitting a snag -- and also with Marquez possibly facing another of the flyweight titleholders, Brian Viloria, later in the year, Marquez, a southpaw, stayed busy with a nontitle bout against Lumacad, 26, of the Philippines. This was a hard-fought and entertaining bout that...
