Trevino caused what perhaps could be described as women's boxing's first major upset, technically knocking out the popular and well-known German fighter Regina Halmich ringside doctors stopped the fight after Regina suffered a major cut under her eye from a four-round, knockdown action. Trevino had suffered a broken left hand in the first round worried the fight would be stopped she continued on and became the new WIBF world Flyweight champion.^[3]

On April 16 1997, after being inactive for about a year, Trevino accepted a nationally televised bout on ABC's Wide World of Sports matched against Brenda Rouse, a fighter from the stable of well known professional boxer Tommy Morrison; the bout was stopped in the first round, after Rouse against the ropes failed to respond to a flurry of punches.^[4]
