O's prospect Suero suspended

BALTIMORE -- The Commissioner's Office announced the 50-game suspension of two Minor League prospects on Monday, sanctioning Baltimore's Ambiorix Suero and the Yankees' Damien Taveras for testing positive for a performance-enhancing substance in violation of the league's Drug Prevention and Treatment Program.

Suero's suspension will begin on the first day of the 2009 season.

Suero allegedly tested positive for Boldenone, while Taveras apparently tested positive for Stanozolol. Suero, 17, spent last season pitching for Baltimore's affiliate in the Dominican Summer League. Suero has made just six professional appearances, logging a 9.53 ERA and walking 11 batters in 5 2/3 innings.
