Giants P Mota gets 100-game ban

San Francisco Giants pitcher Guillermo Mota has been suspended 100 games after testing positive for a performance- enhancing substance, the office of the commissioner of Baseball announced Monday.

Mota, who received a 50-suspension for a performance-enhancing substance violation on November 1, 2006, tested positive for Clenbuterol, which is on the list of substances that violate Major League Baseball's joint drug prevention and treatment program.

"The Giants are disappointed to learn of Guillermo Mota's suspension," the Giants said in a statement. "We support Major League Baseball's drug prevention and treatment program."

The 14-year veteran has made nine appearances with the Giants this season, recording an 0-1 record with a 5.06 earned run average in 10 2/3 innings out of the bullpen. His suspension is effective immediately.
