"Back with the Dodgers after a yearlong absence, reliever Ronald Belisario said Wednesday that he was prevented from entering the United States last year because he tested positive for cocaine.

The positive drug test also resulted in a 25-game suspension issued by Major League Baseball that Belisario will serve at the start of the upcoming season.

Standing in front of his locker before the pitchers and catchers' first workout of the spring, Belisario said he didn't have a cocaine problem and that he had ingested the drug only once.

"I don't have a problem with any drugs," he said."
