When he was young and he walked into a gym for the first time, the way he hit opponents that day impressed his trainers, Chava Mendoza and Gilbert Marquez.

Campas, who had been considered by many Mexicans to be the next Chávez, dropped Trinidad in round two, but he lost by a fourth-round technical knockout for his first professional defeat in 57 bouts.

[3] Campas came back with seven straight wins, including one that gave him the WBO's regional NABO welterweight title, when he knocked out former world champion Genaro Leon in three rounds on August 7, 1995.

After one more knockout win, he tried to gain the WBC and WBA light middleweight titles against Oscar De La Hoya on May 3, 2003, again in Las Vegas.

Campas then suffered a mild upset when he was beaten by the relatively unknown Eric Regan by decision in twelve rounds at Oroville, California.
