Austin Gomber or Ryan Feltner?

MINNEAPOLIS — Another change might be in the works for the Rockies’ starting rotation.

Rookie right-hander Ryan Feltner, who struggled Sunday in a 6-3 loss to the Twins, might be replaced in the rotation by lefty Austin Gomber, who’s struggled in his two appearances since being relegated to the bullpen.

The decision could be made in time for next weekend’s series against Arizona at Coors Field.

“This is a temporary thing,” manager Bud Black said about Gomber’s recent stint in the bullpen. “This is more about giving him a little bit of a break and allowing him to take a step back.”

Black said he liked the way Feltner had been pitching, and he also liked how Feltner matched up against the Marlins and Twins on the just-completed road trip. Feltner, however, gave up five runs on eight hits in four innings Sunday.

“The (Twins) had a good approach and were relatively patient, as evidenced by (Feltner’s) 35-pitch first inning,” Black said. “Ryan really couldn’t get his breaking ball going — curveball or slider. He was ineffective with those two pitches and the fastball command was a little spotty. The ball was in the middle of the plate and they drove them in the first couple of innings.”

Gomber, who gave up a run on two hits and a walk in 2 2/3 innings Sunday, has a 6.55 ERA. Last year, he was 9-9 with a 4.53 ERA that included excellent numbers at Coors Field (5-1, 2.09 ERA in nine starts).

Gomber said he’s been frustrated by his demotion to the bullpen, but he understands why the move was made.

“Over the past three weeks or past month, I haven’t been pitching up to my capability,” Gomber said. “It’s frustrating for myself and for the team. I felt like the starting rotation was going to be a strength for our team and I was a part of that.”
