LOS ANGELES -- Giants reliever Guillermo Mota was suspended Monday for 100 games after testing positive for clenbuterol, a performance-enhancing substance, in violation of Major League Baseball's Joint Drug Prevention and Treatment Program, the Office of the Commissioner announced.
The suspension of Mota, who received a 50-game ban for a performance-enhancing substance violation in November 2006, is effective immediately despite his intention to appeal. His agent, Adam Katz, blamed the positive result on a children's cough medicine.
"Players are responsible for what they put in their bodies. Guillermo understands that," Katz said. "A 100-game suspension for taking a children's cough medicine that contains trace amounts of a prohibited substance, which is what happened here, is severe and unfair and does not reflect the intention of the Joint Drug Prevention and Treatment Program. We will appeal it."
The Giants issued a statement that read simply, "The Giants are disappointed to learn of Guillermo Mota's suspension. We support Major League Baseball's Drug Prevention and Treatment Program."
Said manager Bruce Bochy, "It is what it is and you move on. I really don't have any other comment."
Mota, 38, is 0-1 with a 5.06 ERA in nine appearances in his third season with the Giants, the seventh team he has played for in his 14-year Major League career. He pitched in 52 games last season and had a 3.81 ERA in 80 1/3 innings.
The right-hander was with the Mets when he was suspended the first time and missed the first 50 games of the 2007 season. He's the third Major Leaguer to be suspended for 100 games as a two-time offender. Manny Ramirez and ex-Giant Eliezer Alfonzo are the others.
