He debuted on April 1, 2005 in the Chivas' loss against CF UAG 3-2, but was praised by the then coach Benjamín Galindo. After the loss of 6 players before the FIFA World Cup 2006, Chivas played with a lot of young players, some of them with absolutely no experience in First Division and they managed to reach the semifinals, losing to C.F. Pachuca with a last minute goal.
"El Gauchito" capped his first goal in the Liguilla (Playoffs) of the Clausura 2006 against Chiapas FC. In Apertura 2006, he only played 86 minutes in 3 games. He often played for CD Guadalajara's Lower Division club team CD Tapatío. While Efrain Flores was coach he started every game and contributed to his team's efforts with seven goals.
