The Rockies recalled left-hander Drew Pomeranz to start against the Diamondbacks on Sunday afternoon. Colorado optioned infielder-catcher Jordan Pacheco to Triple-A Colorado Springs to make room on their 25-man roster. Pomeranz, who came over from Cleveland in the Ubaldo Jimenez trade last summer, had a solid spring, going 3-0 with a 0.53 ERA in five starts. He struggled against Arizona, allowing five runs on nine hits in 4 1/3 innings. He struck out three and walked two batters.
