CHICAGO -- The Padres activated right-handed pitcher Jarred Cosart from the 10-day disabled list before Sunday's game against the White Sox and optioned righty reliever Kevin Quackenbush to Triple-A El Paso.
Cosart went on the DL with a right hamstring strain on April 19, and he made two rehab appearances. He was 0-1 with a 3.24 ERA in three games with San Diego, including two starts. Quackenbush was 0-0 with a 3.68 ERA in six appearances.
