Hoffmann (undisclosed) was activated from the 60-day injured list Friday.
Hoffmann was cut loose by the Diamondbacks on Aug. 20, but it didn't take long for him to find a new landing spot in Philly. He made one rehab appearance at Single-A Clearwater on Sept. 4, when he tossed a scoreless inning, and he's since been reinstated from the MiLB IL. He made his debut for Triple-A Lehigh Valley on Friday, allowing one walk while fanning two over 1.1 frames.
