Tigers' infielder Neifi Perez was suspended for 80 games Friday after testing positive for a third time for a banned stimulant, a penalty that finishes his season. Perez was suspended for 25 games on July 6 when he tested positive for a second time. Under baseball's labor contract, a player who tests positive for the first time is sent for counseling. Perez has been the only player suspended by baseball for stimulants since they were banned before the 2006 season.
