MOSLEY (44-5, 37 KO's), the -800 favorite in the BetUS boxing betting odds, has had a flurry of great fights through the years. He first won a world title (IBF lightweight) in August of 1997 against Phillip Holiday, and defended eight times before moving up tot he welterweight division. In June of 200 he scored a 12-round split decision over Oscar De La Hoya to win the WBC welterweight crown, and at that point he was considered by some to be the world's top pound-for-pound fighter. But after three defenses of that crown, Mosley became a victim of styles when he was beaten by Vernon Forrest, who had also beaten him in the 1992 Olympic Trials, in January of 2002. Five months later he lost a rematch to Forrest, but got some redemption when he won the rematch over De La Hoya in September 2003, although that decision was hotly disputed. Mosley's career took a decided downturn when he lost a pair of fights to Winky Wright, and it wasn't until scoring a couple of stoppages over Fernando Vargas in 2006 that anyone paid attention to him again. This all led to a shot at WBA welterweight champ Miguel Angel Cotto last November. It was a great fight, but the younger, stronger Cotto pounded out a decision.

MAYORGA (29-6-1, 23 KO's), the +550 underdog at BetUS, had most of his early fights in Nicaragua and Costa Rica and became known to American audiences when he stopped Andrew "Six Heads" Lewis to win the WBA welterweight title in March of 2002. But it was his third-round TKO of Vernon Forrest in July 2003 that really made some heads turn. Mayorga then scored a majority decision in the rematch, but was frustrated by Cory Spinks, who beat him in a unification fight in December 2003. A comeback fight against Felix Trinidad did not work out well, as he was taken out in eight brutal rounds, but Mayorga did beat Michele Piccirillo for the vacant WBC crown at 154 pounds in August '05. Mayorga was himself a comeback opponent for Oscar De La Hoya two years ago and was almost knocked out in one round before rebounding and lasting eight rounds. Last time out, in November, he scored a majority decision over Vargas.

If Mosley has anything left, he will probably have too much class for Mayorga here. He ought to be able to sit back and counter-punch. And he throws straight punches, which are a good counter-attack for a guy like Mayorga, who throws 'em wide. But that doesn't always work with a guy like Mayorga, who is so highly unorthodox that he can take a guy off his game. He took Forrest by surprise the first time, but I wonder if there is a whole lot of preparation that can be done for him, other than to go in there and fight one's fight.

So you have the boxer against the wide-open brawler. I think the boxer should win, but Mosley is 37 years old, so I don't know I feel strongly enough about it to justify the -800 price. However, there may be some value in the rounds proposition. Mayorga proved himself somewhat resilient against both Trinidad and De La Hoya, although he was pounded pretty hard by both of them. He lasted six against DLH and eight against Trinidad, and Mosley doesn't hit as hard as those guys. So unless Mayorga is so shot that he is going to crumble when he goes out there, I would count on him going some rounds. So it's OVER the 9.5 rounds, as posted in the BetUS boxing betting odds.
