Turnbull (lat) will pitch in an intrasquad game Wednesday at Citizens Bank Park, MLB.com reports.
Turnbull made a rehab start with Triple-A Lehigh Valley on Sept. 22 and threw 52 pitches in a live batting practice session Sept. 27. If he gets through Wednesday's session without any issues, Turnbull could be included on the Phillies' NLDS roster as a long reliever. He's been sidelined since late June with a right lat strain.
