Jason Giambi is free to drop as many pop-ups as Joe Torre will allow, but yet another non-household name finds himself facing suspension writes the Denver Post’s Troy E. Renck.

Jorge Piedra (above), an outfielder on the Rockies’ 40-man roster, expects to be suspended today for violating baseball’s new drug policy. He would become the second major-league player publicly identified, joining Tampa Bay’s Alex Sanchez.

Contacted Sunday by The Denver Post, Piedra said he would discuss his situation after today’s announcement from the commissioner’s office. When asked what could have resulted in a positive test, the 24-year-old indicated he took some pills for a previous injury.

Even though Piedra is a member of the Colorado Springs Sky Sox, he’s on the Rockies’ 40-man roster, and under the new rules, such players are subject to a 10-game suspension without pay.

Piedra played Wednesday for the Rockies, singling in his only at-bat as a pinch hitter in a 14-6 loss to the San Diego Padres. He was called up for one game to replace injured outfielder Dustan Mohr.

Piedra hit .297 with three homers and 10 RBIs in 38 games for the Rockies last season.
