Manny Pacquiao defeated Juan Manuel Marquez in a split decision last night in Las Vegas that is already controversial. It was an action-packed fight, but given the potential payday for a fight between Pacquiao and Floyd Mayweather Jr., it’s not surprising that the decision will be questioned by many.

The reaction from Dan Wetzel of Yahoo! Sports will likely be typical from the boxing world:

When the final bell rang, 12 rounds of furious fighting complete, Juan Manuel Marquez lifted his right fist high into the air, turned to the ringside crowd and offered a knowing wink through an eye nearly swollen shut.

Standing in front of him at that very moment, his opponent, Manny Pacquiao, let his head sag as he turned to walk to his corner. Seconds later Marquez was carried around the ring on the shoulders of two of his corner men. Pacquiao was on his knees in prayer.

What Pacquiao lost was clearer – his cloak of invincibility, his reputation for destruction, even, in some ways, a measure of his credibility.

Marquez is 38 years old and was dominated in his fight with Mayweather.

Attention will now turn to that potential blockbuster fight, and this close call probably won’t dampen excitement for that fight too much.
