Which orthodox fighter beat the highest number of quality southpaws?

I'm sure it is Wlad at HW:
Byrd (twice)
Ibragimov
Chagaev
Tony Thompson (twice)

I think there must be few names from lighter divisions in this thread.

 

Roy beat the most I believe, also I'm pretty sure Roy went a span of 3 years? I think where he only fought southpaws.

High quality...................eh.

 

Wladimir is a good pick heres some others off the top of my head.

Erik Morales = Manny Pacquiao, Paulie Ayala, Daniel Zaragoza, Kevin Kelley, Remigio Molina.

Bernard Hopkins = Antonio Tarver, John David Jackson, Syd Vanderpool, Keith Holmes, Carl Daniels, Robert Allen x3, Winky Wright.

 

BHOP beat some good ones. Winky, Tarver, Holmes, Allen, Jackson.

 

Alexis Arguello: Boza Edwards, Bazooka Limon, Rolando Navarrete, Jose Luis Ramirez, Jim Watt, Andrew Gannigan

Nonito Donaire: Vic Darchinyan, Omar Narvaez, Toshiaki Nishioka, Hernan Marquez, Nordine Oubaali,

James Toney: Michael Nunn, Vassily Jirov, Reggie Johnson

 

You nailed it. I was going to say these two. Mayweather overall, but Wlad in a landslide at heavyweight only.

 

Mayweather: Pac, Guerrero, Judah, Mitchell, Corley, Ortiz.
