Pomeranz (1-0) gave up only two hits while fanning two and walking two for the Rockies, who won the final two games of the set. Jason Hammel gave up one run in four innings of relief to close out the victory and earn his first save of the year.
"He has a very quick arm and he competed very well," Rockies manager Jim Tracy said of his starter.
Edinson Volquez (5-5) was tagged with the loss, giving up two runs on four hits over five frames. He walked four and struck out three.
"He had good tempo and threw the ball better," Reds manager Dusty Baker said of Volquez. "He had a few walks, but we just didn't have a bunch of offense."
