BALTIMORE — Orioles slugger Chris Davis was suspended 25 games without pay on Friday following a positive test for an amphetamine, a punishment that will extend into the postseason and perhaps 2015.

Baltimore started Friday leading the AL East by 10 games with 17 left, so the team will be without the 2013 home run champion into the playoffs.

“I apologize to my teammates, coaches, the Orioles organization and especially the fans,” Davis said. “I made a mistake by taking Adderall. I had permission to use it in the past, but do not have a therapeutic use exemption this year.”

Adderall is a drug often used in the treatment of attention deficit hyperactivity disorder and narcolepsy, and 119 TUEs were issued for 40-man roster players in the year ending with the 2013 postseason. It is, however, also known as a performance and cognitive enhancer.
