Embattled pitcher Jason Grimsley was suspended for 50 games by Major League Baseball on Monday, less than a week after federal agents raided his home during an investigation into performance-enhancing drugs.

Grimsley was suspended for violating baseball's Joint Drug Prevention and Treatment Program. The Arizona Diamondbacks released the reliever last Wednesday and his agent said he did not expect Grimsley to play again.

If he returns, the penalty would take effect when he's placed on a 40-man roster.
