Baltimore Orioles pitcher Troy Patton was suspended 25 games after testing positive for an undisclosed amphetamine, Major League Baseball (MLB) said on Friday.
The 28-year-old lefthander, a one-inning reliever in the middle of a bullpen, went 2-0 with a 3.70 earned-run average (ERA) in 56 games last season.
Patton, who broke into the majors in 2007 with the Houston Astros, has compiled a 5-1 record and 3.04 ERA since getting his first action with Baltimore in 2010.
The suspension will be effective from the start of the 2014 regular season, MLB said in a statement.
