Chapman started on Thursday and worked one perfect inning with two strikeouts while throwing 18 pitches (11 strikes) in his first action since being struck in the face by a Salvador Perez line drive on March 19. The injury required surgery to repair fractures above the left eye and nose. He is expected to have three or four rehab appearances.
Price was pleased with the video and reports he saw on Chapman out of Dayton.
"Not just because the velocity was good and he threw strikes, but he was also working on his offspeed pitches -- his slider and his changeup," Price said. "He's smart enough to know not to just go out there to get his arm in shape, but get a good feel for his offspeed pitches, which will be important when he's activated."
