Round two: Frustrated, Pacquiao came out and missed wildly and started to chase Mayweather early. He trapped him in the corner 90 seconds in, but didn't appear to do significant damage. Mayweather landed a solid right hand that appeared to back up Pacquiao, who responded with a left. Another flurry at the end and a much better round for "Pac Man." Lederman 9-10, Farhood 10-9,

Round three: Mayweather continues to fling the jab and Pacquiao is just lunging trying to land something in response. Pacquiao gets him up against the ropes, but Mayweather escapes.

Round four: Pacquiao starts to find Mayweather, who just guards up on along the ropes and let's him go nuts. Hard hook from Pacquiao, but Mayweather seems to have weathered Pacquiao's first storm. Mayweather shoulder rolls, as if nothing big happened, but that was a huge round for Pacquiao on the judges scorecards and for his confidence. Lederman 9-10, Farhood 9-10.

Round five: Mayweather comes out, once again, working the jab and pushes him back into the ropes. Another head lock from Mayweather. Pacquiao, after a big round, appears to be taking one off. Announcers said he only threw 15 punches. Strange. Lederman 10-9, Farhood 10-9.

Round six: Pacquiao now back, ripping punches and combinations, but Mayweather blocked most of them. The two get tangled up and exchange words. Pacquiao lands a nice left and gets Mayweather up against the ropes and all he does is shake his head -- nothing is getting through. Mayweather beats him back with that stiff jab.

Mayweather is really starting to find his mark and all Pacquiao can do is bully him into the corner with 10 seconds remaining and try to land something in a wild exchange. Seems too little, too late. Mayweather is starting to pull away. Lederman 10-9, Farhood 10-9

Round 10: Pacquiao lands a solid left hand to get things going. He's starting to give chase, but nothing effective still. Pacquiao can't get past the jab, landing just 18 percent of his punches so far. Mayweather might be taking this round off -- he didn't really do much but play keep away. Pacquiao might have just won that round by default because he once again didn't do much, was just busier. Lederman 10-9, Farhood 10-9

Round 11: Mayweather storms out of the gate with a huge right hook, like he wants to finish the Filipino. He's really starting to tee off. Pacquiao still can't find Mayweather consistently. Pacquiao gets him in the corner again, but Mayweather slips out undamaged. He did it again and Mayweather bops him with two clean jabs. Mayweather gives a rare chase and then a straight right at the bell. Lederman 10-9, Farhood 10-9

Round 12: Final round and it appears Pacquiao needs a stop to win. But, he can't put anything together in the first two minutes. With 45 seconds to go, Pacquiao starts to go for broke but still can't find Mayweather, who is just "toying" with him as he raises his glove to the rafters and begins an early celebration. Pacquiao faded down the stretch and Mayweather only got stronger. Lederman 10-9, Farhood 10-9.
