Baseball notes: Padres’ Cameron Maybin tests positive for amphetamine

San Diego Padres outfielder Cameron Maybin was suspended 25 games by Major League Baseball on Wednesday for testing positive for an amphetamine.

Maybin said in a statement released by the players’ union that the failed test was the result of a change in the medication he was using to treat attention deficit disorder.

Under the drug agreement between MLB and the union, 25 games is the penalty for a second positive amphetamine test. A first positive results in six unannounced follow-up tests over the next year.

Maybin, 27, is batting .247 with one home run and nine RBIs in 62 games.

“I understand that I must accept responsibility for this mistake and I will take my punishment and will not challenge my suspension,” Maybin said. “I apologize to my family, friends, fans, teammates, and the entire Padres organization.”
