Davis was called up from Triple-A Albuquerque on Friday, Patrick Lyons of TheDNVR.com reports.
Davis will return to the big-league roster just two days after he was sent down Wednesday, after Brent Suter (oblique) was placed on the 15-day injured list. Davis has produced an inflated 7.47 ERA and 1.91 WHIP with 14 strikeouts over 15.2 innings (four starts) with the Rockies this season.
