Gordon is slated to start Sunday's game against the Giants at Coors Field, Kevin Henry of The Denver Gazette reports.
After being touched up by the Marlins for five runs in five innings during his return from the injured list Tuesday, Gordon carries a 6.69 ERA and 1.59 WHIP over 40.1 innings across 10 appearances (three starts) this season. Despite that rough outing, the right-hander will be awarded a second turn through the rotation, but his grip on a starting role is tenuous. The Rockies called up one of their top pitching prospects, Gabriel Hughes, from Triple-A Albuquerque on Wednesday, and while he's slated to work out of the bullpen initially, he could get a look as the club's No. 5 starter later this summer.
