San Francisco Giants pitcher Guillermo Mota has been suspended for 100 games after testing positive for a performance-enhancing drug. In the 2006 season, Mota received a 5-game suspension for a similar performance-enhancing substance. The MLB Commissioners office claims that Mota tested positive for Clenbuterol.
In his 14th season in the MLB, the Giants relief pitcher is 0-1, with nine strikeouts, and 5.01 ERA. Over Mota’s career he is 39-45 with 681 strikeouts, and 3.92 ERA.
Clenbuterol has a history of usage in Major League Baseball. Kirk Radomski, who was the New York Mets clubhouse employee, admitted to distributing clenbuterol to numerous current and former MLB players during his plea deal.
In September 2010, a similar clenbuterol incident occurred with St. Louis Cardinals minor league shortstop Lainer Bueno. Bueno received a 50-game suspension in the 2011 season for testing positive for clenbuterol.
