Both Martinez and Cotto are proven hardcore fighters, and a clash of their different styles tonight is of particular interest to boxing fans. Although both fighters may be towards the back end of their careers, they still have enough in their tanks to provide enough excitement to pull in a PPV crowd.

Miguel Cotto comes into this fight with a professional record of 38-4, with 31 KO's. Meanwhile, Martinez has a 51-2-2 record, but with just 28 KO's.

Martinez has put on a mixture of performances in recent years, and fans will be hoping they can see the champ boxer at his best tonight, rather than the one who struggled against Martin Murray. Because of that performance some have put some serious question marks over his name, and believe age has finally caught up with him. Whether that's true or not, may be proven in tonight's bout as Cotto will provide a stern test.

Some believe Cotto is giving up too much size in tonight's bout, but others who know him better believe that he knows how to handle himself and size will not be a factor in the match up. Under Freddie Roach he has expertly perfected his body attack, and he will likely look to utilize that tactic tonight.
