Orioles minor league shortstop Alfredo Zambrano, a member of the club's Dominican Summer League team, has been suspended for 50 games for testing positive for metabolites of Nandrolone. Don't know much about them, but they're considered a performance-enhancing substance in violation of the Minor League Drug Prevention and Treatment Program. The suspension begins at the start of next season. Zambrano, 17, batted .140 in 18 games. So much for performance enhancing.
