Andres "Jaguar" Gutierrez (34-0-1, 24KOs) and Marco Antonio Periban (24-3-1, 16KOs), both notched notable stoppage wins at the Palenque El Marques in Queretaro.
Super middleweight Periban, who towered over Jose Miguel Torres from Colombia, felled him with a might straight right in round four. Torres bravely got up, but was unsteady, and Referee Jose Medel had no hesitation in stopping it at one minute seven seconds.
Periban has been in the running for several big fights in the last twelve months. He was being scouted as a potential comeback opponent for Andre Ward and also a possible fight for Julio Cesar Chavez Jr.
Undefeated Gutierrez, who fought as a super featherweight in the contest, picked up his win when Manuel Dionisio Echenique from Argentina couldn't come out for the tenth round due to a worsening cut, as a result of an earlier accidental clash of heads. Shorter but more compact Jaguar fought intensely and at close range, building a big points advantage, before the halt.
Gutierrez is on the verge of a world title shot. The Mexican slugger is looking at trying to secure a showdown with WBA world champion Leo Santa Cruz, who defends his title next Saturday night against former IBF beltholder Kiko Martin.
