For the second time this year, a Tampa Bay Rays minor-league pitcher has been suspended for violating the Drug Prevention program.

Right-hander Steve Geltz was suspended 50 games Monday by the Office of the Commissioner of baseball for a second positive test for a drug of abuse.  A statement released by the Commissioner's Office did not specify the drug Geltz tested positive for.

The reliever was 2-2 with a 3.86 earned run average in 11 games for Tampa Bay's Triple-A affiliate, the Durham Bulls.  

Geltz was acquired in in March 2013 from the Los Angeles Angels in exchange for reliever Dane De La Rosa.  According to the Commissioner's Office, he is the 23rd player to be suspended for violating the Minor League drug program this season.

Meanwhile, Triple-A starter Alex Colome, who was suspended on March 24 after testing positive for a performance-enhancing substance, participated in his first rehab game since his suspension Monday.  

Pitching for the single-A Charlotte Stone Crabs against the New York Mets' single-A affiliate from Port St. Lucie, Colome struck out the first two batters he faced Monday, and reached 96 miles per hour with his fastball in the first inning.  However, he allowed a pair of runs in the second on a wild pitch and a run-scoring single.  He finished with two hits allowed, two wild pitches, three walks and four strikeouts.

Colome has served 31 of his 50-game suspension.
