ESPN boxing experts
Teddy Atlas
ESPN/Friday Night Fights
Pacquiao by controversial decision
To beat Mayweather, you must have fast hands, the quick feet to get the hands there, and the attitude of a volume puncher. Manny has all those attributes.
Rafe Bartholomew

Pacquiao by decision
Pacquiao is such a dynamic and creative offensive fighter that when he decides to throw everything in his arsenal at Mayweather, something will work.
Brian Campbell
ESPN.com
Pacquiao by split decision
Pacquiao's hand speed and activity level will limit Mayweather's output early and sway the judges late.
Nigel Collins
ESPN/Friday Night Fights
Pacquiao by decision
Manny is much faster than Maidana and significantly more accurate with his punches, which would allow him to outwork Floyd and win a close decision.
Juan Manuel Marquez
ESPN Deportes
Mayweather by split decision
Mayweather knows how to handle himself in the ring very well and even knows how to get his opponent to fight at his pace and he takes advantage of that.
Wally Matthews

Mayweather by decision
I believe Mayweather will defeat Pacquiao by a fairly easy decision Saturday night.
Carlos Narvaez
ESPNdeportes.com
Pacquiao by decision
Although Mayweather is taller and also a difficult adversary able to give anyone a bad night, I think this time Pacquiao will earn a close decision and force another millionaire rematch.
Carlos Nava
ESPNdeportes.com
Mayweather by split decision
Floyd Mayweather will decide what kind of fight will be between him and Manny Pacquiao.
Brett Okamoto
ESPNdeportes.com
Mayweather by unanimous decision
The crowd will go wild over some Pacquiao flurries that are fun to watch, but won't hurt Mayweather significantly. May runs away at the end.
Bernardo Osuna
ESPN/Friday Night Fights
Mayweather by split decision
I expect some rocky moments early for Floyd, but anticipate a split decision win for a 48-0 record.
Bernardo Pilatti
ESPNdeportes.com
Pacquiao by decision
A highly technical fight. Pacquiao will begin to loosen up in the fifth round and dominate the battle for a unanimous decision.
Dan Rafael
ESPN.com
Mayweather by decision
I always thought it was a fantastic style match and Mayweather would beat Pacquiao by decision.
Eric Raskin
Grantland.com
Mayweather by decision
Floyd doesn't get flustered, he is brilliant at making adjustments, and he'll make enough of them to win a clear, close decision
Salvador Rodriguez
ESPNdeportes.com
Mayweather by decision
Floyd's intelligence, defense and discipline in the ring will be enough to earn a victory by way of points.
Jorge Eduardo Sánchez
ESPN Deportes boxing host
Mayweather by decision
Manny needs many things to happen to win the match, but he's opposite a brilliant fighter who is used to winning no matter what.
Joe Tessitore
ESPN/Friday Night Fights
Majority draw
I predict scores of 115-113 Mayweather, 114-114, 114-114.
