Clenbuterol or children's cough medicine?

Either way, San Francisco Giants reliever Guillermo Mota was suspended 100 games for testing positive for Clenbuterol, according to Major League Baseball, but Mota swears it was cough medicine.

Mota's agent, Adam Katz, said Mota simply took cough medicine with a tiny amount of the banned substance. Katz said the suspension is "severe and unfair and does not reflect the intention of the Joint Drug Prevention and Treatment Program. We will appeal it."

In the meantime, Mota is ineligible.

MLB isn't budging for now. The suspension was effective immediately, and the Giants' bullpen was short-handed Monday, and it showed in a 9-1 loss to the Los Angeles Dodgers in which starter Barry Zito gave up three runs in six innings.

Mota usually is the first reliever behind Zito, but manager Bruce Bochy had to go elsewhere, so he used Steve Edlefsen and Travis Blackley in the eighth and ninth, and chaos followed.

Aubrey Huff (anxiety disorder) came off the disabled list to fill Mota's roster spot. The bullpen included six pitchers instead of the regular seven, and fans are wondering if hard-throwing Heath Hembree, the 23-year-old closer at Class AAA Fresno, will get the call.

With closer Brian Wilson, key lefty Jeremy Affeldt and Mota out, the bullpen isn't the same. After all, who could have imagined in spring training Edlefsen and Blackley being used in the seventh and eighth innings of a close game at Dodger Stadium?
