According to New York Newsday, Floyd Mayweather Jr. is open to a possible move to middleweight for a fight with WBC/WBO champion Sergio Martinez. Mayweather returned to action on Saturday night, dominating Shane Mosley over twelve rounds to win a unanimous decision.

After the fight was over, Mayweather was asked about some possible options - if a fight with Manny Pacquiao is not made. One reporter asked Mayweather about the possibility of moving up to 160-pounds to fight Martinez, who recently beat Kelly Pavlik for the titles. Mayweather surprised everyone by stating "it's possible."

Mayweather has won titles at 130, 135, 140, 147 and 154. Martinez is not a big middleweight, but he is a lot bigger and stronger than Mayweather. Mayweather could be bluffing to make a deal with Pacquiao. Several years ago, when Mayweather was fighting at 140-pounds, he was demanding a fight with Winky Wright, who at the time was the unified champion at 154. When it came time to make the deal, Mayweather's demands were so one-sided that he couldn't have been serious.
