Capellan, who has pitched in the Majors for the Brewers and the Tigers, was acquired from the Tigers in a trade for right-hander Denny Bautista during the winter. But Capellan suffered an ankle injury early in Spring Training and didn't have much of a chance to impress.
The Rockies made him a starter at Triple-A Colorado Springs, and he did well enough in three starts (2-0, 3.94 ERA in 16 innings) to earn a call up to help a depleted bullpen. In a relief appearance during Saturday night's 11-3 loss to the Dodgers, Capellan gave up a run on three hits in his first inning, then pitched a scoreless eighth, striking out two.
"I felt good," Capellan said. "They got a couple of hits in the first inning but I felt good. I wasn't too excited or anything like that. I just went out there to make the outs, that's it."
