These matchups are pretty rare. Some recent ones that come to mind are PW vs Martinez, Quintana, and Wright and Pacquiao vs D.Diaz. Who are the southpaw fighters who really excel against other southpaws? Active or inactive.
Juanma. 2 big KO victories against Daniel Ponce de Leon and Steven Luevano. Though, you could say that Luevano is really a right handed fighter fighting with a southpaw stance.
There's also Antonio DeMarco vs. Edwin Valero coming up in Feb. I think a powerful right hook like Valero's & JuanMa is key to crushing other southpaws and works pretty good even against orthodox fighters just due to the fact that few southpaws have a good one.
