Playing career Anaheim Angels On June 5, 1999, he was signed by the Anaheim Angels as a nondrafted free agent. His first professional year started out a little bumpy-in 63 games with the Angels of the Dominican Summer League, he hit only .252 with two home runs and 33 RBI.

Contreras' next season-2000 with the Butte Copper Kings-was a complete opposite of his first. In 45 games, he showed great contact by hitting .399. He managed to hit three home runs and drive in 28 runs as well. At one point in his 2000 season, Contreras had scored a run in 13 consecutive games.

In 2001, Contreras played both American and Mexican baseball. With the Rancho Cucamonga Quakes, he hit .271 with three home runs and 37 RBI. His 15 stolen bases showed that he was developing more as a base-stealer than anything else.

In 2002, Contreras played with Rancho Cucamonga again, appearing in 81 games and hitting .271. 2003 was an off-year for Contreras; 12 games with the Cedar Rapids Kernels, he hit only .176.
