Colon, 39, had struggled with injuries since the 2005 season and even missed the entire 2010 season due to injury. The Yankees signed him in 2011, and he went 8-10 with an ERA of 4.00. This season Colon has been even better, going 10-9 with an ERA of 3.43 for Oakland.
Before the positive test for testosterone, there was scrutiny over the stem cell procedure Colon had out of the country in 2011 which helped him in his comeback. Colon is the fifth major league player to be suspended for a positive test this season.
Colon said in a statement:
"I apologize to the fans, to my teammates and to the Oakland A's," he said in a statement released by the players' association. "I accept responsibility for my actions and I will serve my suspension as required by the Joint Drug Program."
