"In a companion 10 rounder, unbeaten Jimmy Heair of Glendale, Calif., knocked out Tury Pineda of Mexicali, Mexico, in the 4th round. A left hook staggered Pineda and Heair put him down with a right to the head. The end came abruptly after 1:27 of the 4th round to climax what had been a wild three previous rounds in which both lightweights staged a slugfest from bell-to-bell that had the crowd in a frenzy." -Associated Press
