1987-08-15 Louie Espinoza w co 9 (15) Mike Ayala, Freeman Coliseum, San Antonio, Texas, USA - WBA. Referee: Bobby Ferrara. Espinoza (121½) proved too strong for his veteran challenger, who despite fighting with skill and courage over the first eight rounds was unable to make his best punches tell. Cut over the right eye in the fifth, Ayala (122) continued to rally but it was Espinoza who was getting the better of it as the local man began to get worn down. In the ninth, from out of the blue came the finish as a left hook to the body saw Ayala drop to his knees to be counted out after 37 seconds of the round had elapsed.
At their convention, in October, it was announced by the WBA that in future the weight class would be contested over 12 rounds if held under their auspices.
