BALTIMORE (AP) Opening day will have a different meaning this year for Baltimore Orioles reliever Troy Patton.

When the Orioles launch the 2014 season at Camden Yards on March 31 against the defending champion Boston Red Sox, Patton will start serving the 25-game suspension he received in December for testing positive for a banned amphetamine.

Patton took Adderall, a drug commonly used to combat Attention Deficit Hyperactivity Disorder, late in the 2013 season and then was given a random drug test. Because Patton did not have a therapeutic use exemption for Adderall and it was his second positive test for a banned stimulant, Baltimore's left-handed relief specialist was suspended and will lose $174,180 of his $1,275,000 salary.

Patton says "it was a stupid mistake, especially having failed one prior test."
