Cordero has pitched in only six games, allowing one run in 4 1-3 innings. Jon Rauch has been serving as the closer in Cordero's absence.

Cordero, who has been on the disabled list since April 30, was diagnosed early in the season with tendinitis in his throwing shoulder. The few times he did pitch, he lacked his usual velocity. Later, doctors discovered a torn lat muscle just below his pitching shoulder. Attempts at rehabilitation failed to improve the shoulder, and another examination on Monday revealed the torn labrum.

Cordero led the majors with 47 saves in 2005, then had 29 in 2006 and 37 last year.
