Kubel was arguably the team's best offensive performer through July, but he hit just .159 in August and so far in September he's hitting .140.
"Just trying to give everybody playing a little bit so he sat out a little," D-backs manager Kirk Gibson said. "He struggled in August and really this month has been hot and cold. Ever since Eaton's been here, I've wanted to play Eaton every day and put him at the top of the order and it's just trimmed people's time out. He's in there tonight, we know what he's capable of doing and we'd like to see him finish strong. We'll keep rotating probably."
Kubel snapped the hitless streak in his first at-bat Saturday night, driving in a run on a single to center off Rockies right-hander Jhoulys Chacin.
Kubel is careful not to complain about a lack of playing time given his struggles, but he also feels like he has hit into some tough luck.
"It's getting better," Kubel said of his approach at the plate. "It's just timing. You're not going to fix that by not playing. It's tough, but like I said there will be times where it will come back and click, just a better feeling. That's just the way it's going right now. We've got a lot of guys here so that's just the way it is."
