Filipino boxing sensation Manny Pacquiao will take on Puerto Rico’s Miguel Cotto for his WBO title at the MGM Grand Garden Arena in Las Vegas tonight, in another highly-anticipated bout in the welterweight division.

Pacquiao weighed in at 144 pounds, his heaviest ever, while Miguel Cotto came in at 145 pounds for their scheduled 12-round fight.

The entire Philippines and the rest of the boxing world will be hoping Pacman knocks the Puerto Rican out to keep the Filipino on course for next year’s clash against Floyd Mayweather Jr.

Despite the Puerto Rican being the champion, Manny is a strong favorite to beat his opponent. He is bidding for a world title at a fifth different weight and was backed by enthusiastic supporters ahead of the eagerly-anticipated bout.

Qualms about Cotto’s ability to beat Pacquiao stem from a devastating defeat, the only one of his pro career, to Antonio Margarito last year.

A victory for Pacman will bolster his claim to immortality. But win or lose, the 30-year-old has already secured his spot in boxing history. Pacquiao is a household name that everyone knows and he is widely considered to be the best pound-for-pound boxer in the world.

The first three rounds will be crucial for both fighters and Freddie Roach said their plan is to hit Cotto with some big shots from the opening bell.

There are so many ways this fight could go, but one thing’s for sure: it’s going to be a great fight.

UPDATE: Manny Pacquiao is the new WBO Welterweight Champion after dominating the bout against Miguel Cotto. Pacquiao won via TKO in the 12th round.
