MGM Grand, Las Vegas - The weights are in for Saturday's anticipated trilogy showdown between Manny Pacquiao (53-3-2, 38KOs) and Juan Manuel Marquez (53-5-1, 39KOs). The fight takes place at a catch-weight of 144-pounds, and Pacquiao's WBO welterweight title is on the line. Photos by Chris Farina/Top Rank.

Pacquiao was shredded and weighed 143-pounds. Marquez was beefed up, with a lot of muscle, and weighed 142-pounds.

Making his Top Rank debut, WBO welterweight champion Timothy Bradley (27-0, 11KOs) was shredded and ripped up as usual, coming in at 140-pounds. Joel Casamayor (38-5-1, 22KOs) was a little dry and had to strip down. Even after stripping down, he was still one pound over, at 141-pounds, and has two hours to make the weight. Losing one pound is usually not a problem.

In a junior welterweight clash, Breidis Prescott (24-3, 19KOs) weighed in at the limit of 140-pounds. Undefeated Mike Alvarado (31-0, 22KOs) was in top form as well, also coming in at 140.

The first boxers to step on scale, were junior lightweights. Juan Carlos Burgos (27-1, 19KOs) came in at 129-pounds, while Luis Cruz (19-0, 15KOs) came in at the limit of 130-pounds. Burgos vs. Cruz opens up the live HBO pay-per-view card.

Undefeated Top Rank prospect Jose Benavidez Jr. came in at 141-pounds, and Sammy Santana was 140. The untelevised fight is scheduled for six rounds of action.
