Main Card

Manny Pacquiao def. Shane Mosley
(for WBO welterweight championship)

Pacquiao cruises to a unanimous-decision victory over Mosley to retain his title in a successful return to the welterweight division (after defeating Antonio Margarito at super welterweight). The aging Mosley -- outclassed throughout the 12 rounds -- was knocked down in the third round and did not trouble his opponent much at all, although he got credit for a knockdown when Pacquiao slipped in the 10th. Pacquiao has now won his past 14 fights since losing to Erik Morales in 2005. Mosley, fighting at welterweight for the 13th time, had split his past two fights in the division (he lost to Floyd Mayweather Jr. in 2010 and defeated Margarito in 2009).

Jorge Arce def. Wilfredo Vazquez Jr.
(for WBO super bantamweight title)

Arce takes Vazquez's super bantmeweight belt after the bout is stopped in the 12th round, with Vazquez on the ropes following a round of pummeling from Arce. The bout was a back-and-forth affair, with Vazquez able to drop Arce with a left hook near the end of the fourth round, but the Mexican's strength and toughness proved to be the difference late in the fight.

Kelly Pavlik def. Alfonso Lopez (super middleweight bout)

Pavlik takes a majority decision victory on his return to the ring following a 13-month layoff after his loss to Sergio Martinez. Pavlik was scheduled to fight on the undercard of Pacquiao's previous bout, but suffered a rib injury two weeks before the fight and had to pull out. He then checked into the Betty Ford Center to undergo treatment for alcohol abuse. Lopez suffers his first loss after entering the fight 21-0 with 16 knockouts.

Mike Alvarado def. Ray Narh (junior welterweight bout)

Alvarado raises his record to 30-0 after Narh fails to come out after the third round, making it four consecutive fights for Alvarez ending before the fifth round. Narh (25-1) had won 15 consecutive fights since suffering a first-round knockout against Almazbek Raiymkulov in 2004.
