Gray (abdomen) will pitch for High-A Modesto on Friday, before presumably rejoining the Rockies' rotation, the Denver Post's Patrick Saunders reports.
Gray is pain free, and Friday's rehab outing should represent his final tuneup before heading back to the big leagues. He would be on track to step into the rotation for next weekend's series at home against the Dodgers. Gray has the stuff to profile near the front of a big league rotation, but it's always risky to use him when the Rockies are at home. That said, he is an excellent streaming option in his road starts.
