Davis was recalled from Triple-A Albuquerque on Sunday.
Kyle Freeland (oblique) and Peter Lambert (biceps) have landed on the injured list the past two days, leaving Colorado with some holes in its starting rotation. Davis has a 10.61 ERA, 2.25 WHIP and 16:10 K:BB across 18.2 major-league innings this season, but he could receive some starts down the stretch given the injuries to Rockies starting pitchers. The Rockies haven't formally clarified whether Davis will immediately slide into the rotation or if he'll be deployed out of the bullpen initially.
