Jaime Munguia TKO11 Spike O'Sullivan... In San Antonio, Texas, former WBO 154-pound title holder Jaime Munguia (35-0) won his middleweight debut, stopping Ireland's Gary "Spike" O'Sullivan in round eleven. O'Sullivan performed respectably, makingit a competitive fight early on, but Munguia began to dominate as the rounds wore on. In round eleven, Munguia was pummeling O'Sullivan against the ropes, and a white towel of surrender came flying in from O'Sullivan's corner just as their man went down. O'Sullivan is now 30-4 and by way of comparison, he lost to David Lemieux in one round, Chris Eubank in seven and dropped a twelve-round decision to Billy Joe Saunders.   source: dazn
