Oakland's Colon suspended 50 games after positive drug test

New York, NY – Oakland Athletics pitcher Bartolo Colon has been suspended 50 games for violating baseball's drug policy.

The Office of the Commissioner of Baseball said Colon tested positive for testosterone.

It's the second such suspension in a week. San Francisco All-Star outfielder Melky Cabrera was hit with a 50-game penalty last week after also testing positive for testosterone.

"I apologize to the fans, to my teammates and to the Oakland A's," said Colon in a statement through the MLB players union. "I accept responsibility for my actions and I will serve my suspension as required by the Joint Drug Program."

Colon is 10-9 with a 3.43 earned run average in 24 starts this season. He led the Oakland pitching staff in victories and ERA, and was slated to start Thursday in the opener of a big series against fellow wild card contending Tampa Bay.

"The Oakland Athletics are disappointed to learn of today's suspension of pitcher Bartolo Colon," the team said in a statement Wednesday. "The organization fully supports Major League Baseball's Joint Drug Prevention and Treatment Program and its efforts to eliminate performance-enhancing substances from our game. Per the Basic Agreement, the A's will have no further comment."

The 39-year-old right-hander has rejuvenated his career after missing all of the 2010 season because of injury. He returned with the New York Yankees in 2011 and posted a mark of 8-10 with a 4.00 ERA in 29 games.

Colon won the AL Cy Young in 2005 with the Angels. The two-time All-Star has also pitched for the Indians, Expos, White Sox and Red Sox.
