San Francisco Giants all-star outfielder Melky Cabrera was suspended 50 games by Major League Baseball on Wednesday after violating the league's Joint Drug Prevention and Treatment Program, according to a tweet from the official account for Major League Baseball.
Cabrera tested positive for testosterone. His suspension is effective immediately.
Batting .346, he currently has the second-best batting average in the National League and has led the Giants to the top of the NL West in a tie with the Los Angeles Dodgers. Cabrera was also the MVP of the 2012 All-Star Game.
