LOS ANGELES (CBS/AP) — Reigning NL batting champion Dee Gordon of the Miami Marlins says he unknowingly took the performance-enhancing drug that led to his 80-game suspension.

The startling announcement of the suspension by Major League Baseball came shortly after the Marlins’ victory at Los Angeles on Thursday night. MLB said Gordon tested positive for exogenous Testosterone and Clostebol.

The big season helped him earn a $50 million, five-year contract he signed in January. He had been traded to the Marlins by the Los Angeles Dodgers in 2014.

Marlins president David Samson said the Marlins “completely support the drug prevention program in every way.”
