1975-06-20 Ruben Olivares w rsc 2 (15) Bobby Chacon, Inglewood Forum, Los Angeles, California, USA - WBC. Referee: Larry Rozadilla. Having to get off 16 pounds in ten days left Chacon (124½) so weak that he should not have been allowed to fight. Although the contest started slowly and there was little to talk about in the first round, once the second was underway Olivares (125¼) took over and soon had Chacon on the floor from a left-right combination. Back on his feet but taking a beating, Chacon was then dropped by a vicious left hook. That should have been it, but after scrambling up and being subjected to a hail of blows that left him helpless on the ropes the referee came to his rescue at 2.29.
