Juan Manuel Marquez weighed in at a sculpted 142 pounds Friday for his third fight against Manny Pacquiao, who came in a pound below the welterweight-title catch-weight limit at 143.

Marquez, 38, flashed an ultimate six-pack abdomen after an 11-week training course under a controversial new strength coach.

Tonight at MGM Grand Garden Arena, Marquez wants to make the punches he lands against Pacquiao have more effect. The two fought to a draw in 2004, and Pacquiao won a split decision in 2008.

Why is Marquez acting so cocky? Doesn’t he know that he’s going to get knocked out?
