GLENDALE, Ariz. - Ronald Belisario spent last season in Venezuela instead of with the Los Angeles Dodgers due to visa problems. The reason? A positive test for cocaine.

Belisario says he only used the drug once, but doesn't remember when he tried it, when he tested positive or who administered the test. He said he must serve a 25-game suspension. Major League Baseball has not announced any disciplinary measures.

"I don't have a problem with drugs, I'm good," Belisario said yesterday, the first day of workouts for Dodgers pitchers and catchers at spring training.

Belisario has had a checkered past, derailing what was once a promising career. As a rookie in 2009, he had a 2.04 ERA in 69 appearances despite getting a late start to the season due to visa problems.

Belisario again had visa issues the following year, in part because of a DUI arrest in Pasadena, California, in 2009. After his superb rookie season, Belisario's ERA ballooned to 5.04 in 59 games during his troublesome 2010 season.

He spent last season playing in Venezuela after the positive test for cocaine prevented him from obtaining the necessary paperwork to enter the United States.
