San Francisco Giants reliever Guillermo Mota was suspended for 100 games on Monday, becoming the third major-league player penalized twice for positive drug tests.

The commissioner's office said the 38-year-old righthander tested positive for Clenbuterol. Mota also was suspended for the first 50 games of the 2007 season while with the Mets.

The Players Association filed a grievance challenging the suspension. An arbitrator will hear the grievance.

Outfielder Manny Ramirez and catcher Eliezer Alfonzo are the only previous players to twice test positive.

No player ever has tested positive three times, which earns a lifetime ban.

Clemens trial goes on

A short clip from Mike Wallace's 60 Minutes interview with Roger Clemens in 2008 provided just enough ambiguity for the judge to rule it out, hurting the government's hopes of proving one piece of its case against the 11-time all-star pitcher.

Lawyers for Clemens also entered their reasons to strike testimony from former teammate Andy Pettitte.

The trial focuses on whether Clemens lied to Congress in 2008 when he said he had never used human-growth hormone and steroids.

A trial last year ended in a mistrial.
