SAN FRANCISCO, CA - San Francisco Giants outfielder Melky Cabrera has been suspended for 50 games without pay after testing positive for testosterone.
 
The commissioner's office says the suspension is effective immediately. Major League Baseball said on Wednesday that Cabrera tested positive for the banned performance-enhancing substance, which violates MLB's joint drug prevention and treatment program.
 
The MVP of the All-Star game last month, Cabrera is batting .346 with 11 home runs and 60 RBIs in his first season with San Francisco.
