EDGE Analysis

Marsh suffered a cramp in his right hamstring at Lehigh Valley on Sunday, which is the same hamstring in which he suffered the strain that sent him to the injured list. However, after three days of rest, Marsh will play Thursday and Friday before being evaluated for a potential return to the Phillies' active roster.
