<img alt= right-handed reliever Guillermo Mota has received a 100-game suspension for testing positive for clenbuterol, which is classified as a performance-enhancing drug, Major League Baseball announced.

Mota's agent, Adam Katz, released a statement saying his client tested positive because he took 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 Major League Baseball Players Association has already filed a grievance on Mota's behalf, the AP reports. The grievance will be heard by an arbitrator.

Mota, 38, was suspended 50 games in December of 2006 for a positive drug test. He missed the first 50 games of the 2007 season while a member of the Mets because of the suspension.

Mota has a 5.06 ERA in nine games for the Giants this season, allowing six earned runs in 10 2/3 innings.

The Giants released the following statement:
"The Giants are disappointed to learn of Guillermo Mota’s suspension.  We support Major League Baseball's Drug Prevention and Treatment Program.”
