Miguel Cotto's trainer Pedro Diaz says he's certain that the Puerto Rican superstar can be the man to take the undefeated record of Floyd Mayweather Jr when the two meet on May 5 in Las Vegas, live on HBO pay-per-view.

Diaz, who joined Cotto's camp for his December win over Antonio Margarito, intrigued many with his no-nonsense approach to boxing training, which we got to see bits of on the Cotto-Margarito edition of HBO's "24/7," and he believes he and Cotto have the right chemistry to take down Mayweather.

"Like everything in life, it takes desire, dedication and discipline to meet expectations. You also need a good head, heart and courage. I think it's an equation that must be present not only for boxing but for life. To everyone who says that Miguel has no chance [to beat Mayweather], I tell them to watch the fight and when the end result is a victory for Miguel - we'll talk."

Cotto (37-2, 30 KO) is currently a pretty heavy underdog, at +450-500 compared to Mayweather's -700, but the odds aren't unreasonable or anything. They seem about right to me: Cotto should be given little chance, and a win should be considered a major upset, but he's not some hack trying to do the impossible.

He's a good fighter trying to do the very unlikely, and that has happened before. Bigger upsets happen every year, at least in terms of flat betting odds. This, of course, would get slightly more fame and media attention than something like Jorge Arce over Wilfredo Vazquez Jr, or Lamont Peterson over Amir Khan.

This fight is now just under one month away. Don't forget that "24/7" premieres this Saturday night on HBO at 9:45 p.m. EDT.
