The Mayweather/Guerrero undercard features Abner Mares fighting Daniel Ponce de Leon bout between two tough Mexican boxers. Mares is signed with Golden Boy and probably most famous for his KO victory over Joseph Agbeko, which came via a blatant low blow that the referee did not call. The current odds for Abner Mares to win are -255 with Ponce de Leon at +215.
Even though this fight is being sold as a "war" Abner and Ponce de Leon are friends outside of the ring and Mares might not have the same ferocity he had in his previous fights. The odds maker has set the total rounds at 9.5, with the over being strongly favored at -360.
