The Major League Baseball has announced that Baltimore Orioles relief pitcher Troy Patton was banned for 25 games for a second positive amphetamine test.
Under the drug agreement between MLB and its players' union, a first positive test only results in follow-up testing, Xinhua reported Friday.
Patton, 28, became the 15th player suspended this year under the big league drug program as a result on MLB's Biogenesis investigation.
Patton was 2-0 with a 3.70 Earned Run Average (ERA) this year in 56 relief appearances.
