Butler pitched just one inning before being removed with "right shoulder fatigue," according to Patrick Saunders of The Denver Post. He allowed a run on two hits, walking a pair and struggling to find the strike zone throughout his inning of work.
Things just went downhill from there for Rockies pitching, as Scott Oberg allowed four runs, three earned, in an inning of work, closer LaTroy Hawkins gave up five runs on five hits while only managing to record one out and Rex Brothers again struggling with control, walking a pair, but managing to escape his inning of work without allowing a run.
Former Rockie Drew Pomeranz, on the other hand, was strong, allowing just two hits in six shutout innings, walking one and striking out six.
The Rockies did get on the board in the seventh against A's reliever Dan Otero when Nick Hundley singled home Wilin Rosario and then scored on a DJ LeMahieu base hit.
The Rockies are back in action tomorrow as lefty Tyler Matzek takes the mound against the division-rival Giants at Scottsdale Stadium. First pitch is set for 2:05 MDT.
