"It's August, there should be some sort of concern," Upton said. "We feel like we're a team that can win ballgames, but we're not doing anything great right now and if we're going to make a push we're going to have to start playing great and putting together some runs."
All season, it seems, the D-backs have been talking about going on a prolonged winning streak -- something they did in May 2011 and are convinced they can do again.
"Every day we come in here and we hold onto the fact that we're capable of doing that," D-backs manager Kirk Gibson said.
The D-backs entered play Wednesday night 5 1/2 games behind the first-place Dodgers in the National League West.
"We have to just keep grinding," catcher Miguel Montero said. "It's frustrating because we had real high expectations for this year. That's just the way the game goes sometimes. We still have time, but time is getting shorter."
