1987-11-21 Julio Cesar Chavez w rtd 11 (12) Edwin Rosario, Hilton Hotel, Las Vegas, Nevada, USA - WBA. Referee: Richard Steele. Strong and tireless, right from the opening bell the challenger walked through Rosario (135) as if he was not there, and even when he was hit he merely came back with something better to dishearten the champion. From the fifth round onwards it was all Chavez (134¾), even though Rosario was fighting back, and it was the left hook to the body that was gradually draining all of the champion’s resistance. In the tenth when Rosario’s left eye began to close it looked as though the fight was nearing its end, but somehow he got through the round before coming out to face his tormentor for the 11th. However, there was no respite, Rosario being hammered around the ring non-stop. The finish, timed at 2.36, came when Rosario's corner threw in the towel after his gumshield had been knocked out.
