Philadelphia Phillies rookie infielder Freddy Galvis has been suspended 50 games by Major League Baseball for using a banned substance.
Galvis is currently on the disabled list with a back injury and will begin serving his suspension immediately. MLB says Galvis tested positive for a metabolite of Clostebol, a performance-enhancing substance.
Galvis says a ''trace amount'' of the substance was found in his urine and he can't understand how it got there.
Galvis had filled in nicely for injured second baseman Chase Utley before getting hurt. He was batting .226 with three homers, 15 doubles and 24 RBIs. It's likely Galvis will be on the DL for the duration of his suspension.
