I don't know why it was stopped, Cotto wasn't in anymore trouble than he has been already, he should have been allowed to finish the fight.
Pacman was superb, yet again.

Has to be?1. Manny Pacquiao (140)
2. Floyd Mayweather Jr. (147)

I think Pacman was offering the corner a way out, throw the towel in, he showed a different intent this round, had the ref not stopped it, it would have been round 9 all over, was the right call. Pacman started that round looking for blood and there was zero reply when Cotto was cornered.
That was a truly awesome display, that performance was so completely dominant its really the first time I've considered Pacman having a really good chance at Mayweather, that fight I would pay a lot to see.
EDIT:_, the ref's m8 probably had a big bet on the 12th round aswell![]()

This.Mayweather is the only guy who has hand speed and agility to match Pacquiao. I would love to see Pacquiao take Mayweather apart, surely this would be the most eagerly anticipated fight of the past decade, of any division

Did Mayweather 'retire' again, after fighting Marquez? Or is he back on the scene again properly now?![]()

That should have been stopped in the 9th or 10th, by the ref or from Cottos corner.
Big Kev, I think Kenny was right to stop it, even in the 12th. As the commentators said, "It can only take one punch".
Wtf ref? He decides to stop it in the final round? Maybe he missed all the punishment Cotto has been taking in the previous few rounds
Strange point to stop it, but Cotto was outclassed. Mayweather for next May I hope.
This.
I'd love to see pacman destroy pretty boys perfect record along with his smugness!
The guy fought flawlessy tonight![]()
