Jhonny Gonzalez spent all of fight week trying to convince people that he wasn't an old 31-year-old fighter, and that he still had what it took to upset Abner Mares.
Few were willing to give him more than a puncher's chance, and that's all it took.
Gonzalez (55-8, 47 KO) dropped Mares (26-1-1, 14 KO) twice in Round 1, and scored an absolutely stunning knockout to recapture the WBC Featherweight Championship Saturday night in Carson, California.
Mares entered the fight as a huge favorite, but it was a devastating Gonzalez left hand in the bout's opening stanza that stole the show.
In the opening contest, Leo Santa Cruz claimed a share of the WBC Super Bantamweight Championship in extremely impressive fashion by stopping former champion Victor Terrazas in Round 3.
Santa Cruz blew threw his opponent with his customary pressure and aggression, swelling his right eye completely shut, and dropping him twice in the third round.
Terrazas rose from both knockdowns, but informed the referee that he could not see out of his right eye, which forced the stoppage.
