Three-division, five-time champion, Shane Mosley (46-6-1, 39 KOs) is very confident about his ability to score a knockout victory over Manny Pacquiao (52-3-2, 38 KOs) on May 7 at the MGM Grand in Las Vegas. Mosley believes that he needs to redeem himself for his two prior performances, a May decision loss to a Floyd Mayweather Jr., and September's draw with Sergio Mora. Pacquiao is coming off November's dominating twelve round decision over ex-titlist Antonio Margarito.

In the second round of his fight with Mayweather, he was able to land a punch that probably hurt the unbeaten fighter worse than any fighter he has ever faced in the past. If Mosley hurts Pacquiao that way, Mosley believes that he will finish him. Looking over Pacquiao's record, he doesn't see a harder puncher on the list.

"I hit [Ricardo] Mayorga on the chin with a left hook at the last bell, and he looked at me like he was in awe with the punching power that I had. I don't think that he had been hit by anybody that hard in his entire boxing career. I hit extremely hard. Even some cruiserweights that I've sparred with They will tell me how heavy and how hard my shots are," said Mosley to FanHouse.

"It's a different shot. I mean, you saw that Margarito took a beating from Pacquiao. His eyes were closed and everything. But Pacquiao couldn't rock him on the chin. He hurt him to the body, but couldn't rock him on the chin. So it's going to be a different sort of shot that Pacquiao has never felt before."
