Colorado loaded the bases on two walks and Michael McKenry's third hit of the game before Barnes singled to left with one out against Wesley Wright (0-2). Drew Stubbs then scored on a wild pitch, helping the Rockies stop a three-game slide.
Rob Scahill (1-0) pitched a scoreless inning for his second major league win and Adam Ottavino got three outs for his first career save. Scahill was recalled from Triple-A Colorado Springs before the game, bolstering Colorado's bullpen after it used eight relievers in Tuesday night's 16-inning loss.
