Veteran Ben Zobrist contributed with two hits and three RBIs, and the red-hot Billy Burns notched three more hits to raise his Cactus League average to .409.
A's starter Drew Pomeranz also impressed, bouncing back from a rocky outing to fire six scoreless innings. The lefty, who will likely begin the season as the club's No. 5 starter, allowed just two hits and one walk and struck out six.
"He pitched well. He pitched really good," former teammate Carlos Gonzalez said of Pomeranz. "He was hitting spots. His curveball was effective today, too. He has that big curveball. I've never faced him before. I saw the ball really well coming out of his hands."
Rockies starter Eddie Butler was limited to one inning because of right shoulder fatigue. The right-hander was responsible for one run on two hits with two walks.
"I haven't even talked to him yet," manager Walt Weiss said after the game. "He came out, went up in the training room. It sounds like it's better than it looked like, so we're hopeful he'll be fine."
In the seventh, Colorado's Wilin Rosario doubled and scored on a single by Nick Hundley against righty Dan Otero. DJ LeMahieu also had an RBI single in the inning.
A's up next: Lefty Barry Zito is set to make what could potentially be his final outing with Oakland on Tuesday, a road start against the Angels at 1:10 p.m. PT at Tempe Diablo Stadium. Zito has greatly impressed with a 2.30 ERA this spring, but the A's aren't expected to have room on their Opening Day roster for the comeback hopeful, who will surely be pitching in front of other teams' scouts.
