BIGGEST WINNER
Shane Mosley: Talk about an easy choice. Mosley went from a faded star facing the end of his career to the talk of boxing at 37. His knockout of Antonio Margarito on Saturday in Los Angeles was one of the most impressive performances in years.

BIGGEST LOSER
Antonio Margarito: Margarito has nothing to be ashamed of. The brawler from Tijuana simply ran into a better, quicker-handed boxer with resilience and determination comparable to his own. That said, all the momentum he had built came to a sudden end.

BIGGEST LOSER II
Antonio Margarito: Well, actually, Margarito might have something to be extremely ashamed of. Officials reportedly found a substance resembling plaster of Paris in the fighter’s hand wraps. If that proves to be true, his reputation will be seriously sullied.

SMARTEST TRAINER
Naazim Richardson: We’re not referring to the fight itself here, although his game plan worked to perfection. Richardson was the one who noticed something odd about Margarito’s hand wraps and had the authorities investigate. He also discovered a problem with Felix Trinidad’s wraps when he fought Bernard Hopkins, another of Richardson’s fighters.

BIGGEST WINNER II
Miguel Cotto: In his next fight, the Puerto Rican is expected to face damaged goods in Margarito. Or, if neither that fight nor Mosley-Floyd Mayweather Jr. can be made, another good option is Mosley, a fighter he has already beaten. Either way, he’ll make a lot of money and have a good chance to win.

MOST ADVANCED
Matt Korobov: The former amateur star is 3-0 after knocking out an overmatched Jose Florentino in the first round on the undercard of Mosley-Margarito but fights like a veteran. Korobov, 27, could be ready for a world title shot after 10 fights.

BIGGEST CROWD
Saturday night at Staples Center: The crowd of 20,820 at the Staples Center was a record for any sport at the 10-year-old downtown Los Angeles arena, which hosts the Lakers and Clippers of the NBA and Kings of the NHL. The place rocked, particularly when Margarito was introduced and when it became clear the fans were witnessing something historic.

BEST FREE PUBLICITY
Pacquiao-Hatton The ridiculous on-again-off-again negotiations between Manny Pacquiao and Ricky Hatton was reported on worldwide, providing the promotion with invaluable free publicity. It was as if Arum concocted the whole thing. Think that’s possible?

BIGGEST DISS
Jorge Arce The super flyweight from Mexico who is scheduled to face Vic Darchinyan on Feb. 7 in Anaheim, Calif., failed to show up at a news conference on Saturday to promote the fight.

BIGGEST DISS II
Darchinyan: Darchinyan, as outspoken as any fighter, used Arce's absence to diss him right back. “There is only one reason he is not here: He is scared. He's a tough fighter, but I don't expect much of a challenge. I'm going to demolish him.”

BEST QUOTE
Margarito: “I feel OK. I was just getting caught over and over.” Yeah, no kidding.
