Mariot (ankle) is set to begin his rehab assignment Friday at High-A Clearwater, Meghan Montemurro of The News Journal reports.

Analysis:

Mariot began the season on the disabled list after suffering a sprained ankle early on in spring training. He'll get back on the mound and face live batters Friday at High-A, but it's unclear how many rehab appearances the Phillies want him to make before they're comfortable with activating him from the disabled list. Once activated, Mariot will likely be optioned to Triple-A Lehigh Valley.
