Juan Pierre was originally slated to miss six weeks with a sprained knee but was reinstated from the DL on Friday after sitting out just 20 games. He injured it sliding into second on June 29.

To make room for Pierre on the 25-man roster, outfielder Delwyn Young, a former State Championship MVP at Riverside Community College, was placed on the DL with an oblique strain.
Young injured the oblique on Wednesday in a pinch-hitting performance at Colorado.
