Review: 2012-09-15, even with two knockdowns, the fight between Guillermo Rigondeaux and Robert Marroquin has not been very exciting: two stars. The undefeated Guillermo Rigondeaux (10-0-0) entered as the No.4 super bantamweight in the world while Robert Marroquin (22-1-0) entered as the No.46. Rigondeaux vs Marroquin is valid for the WBA World super bantamweight title; undercard of Julio Cesar Chavez Jr vs Sergio Gabriel Martinez. Watch the video!
