Reliever Guillermo Mota was suspended for 50 games Wednesday for violating Major League Baseball's drug policy.

The 33-year-old pitcher finished this season with the New York Mets and filed for free agency Tuesday. His suspension will take effect at the start of next season.

"I have no one to blame but myself," Mota said. "I used extremely poor judgment and deserve to be held accountable."

Mota was 4-3 with a 4.53 ERA this season with Cleveland and the Mets.

This is the third suspension since the penalty for first offenders increased from 10 days to 50 games this year.

Pitcher Yusaku Iriki tested positive while on the New York Mets roster during spring training, and pitcher Jason Grimsley was penalized after authorities tracked a package containing human growth hormone to his home. Grimsley already had been released by Arizona when he was suspended.
