• Towers continues to work the phones in advance of the July 31 non-waiver Trade Deadline.

"A lot of clubs are probably like us, kind of still trying to wait until the very end to figure out where you're at," Towers said. "We're still within five games, but a lot can happen in a couple of weeks. You could have a big winning streak, you could have a big losing streak and it could change things."

• D-backs right-hander Ian Kennedy, a 21-game winner in 2011, has struggled to find consistency this year.

"Doesn't have quite the location he had last year," Towers said. "I think he was down in the zone a lot more last year, driving the ball down in the zone. His command is just off, he's elevating too many balls and getting too much of the plate."

Kennedy's velocity has been down, but Towers did not sound overly concerned about it.

"It could be the innings of last year," Towers said. "You're just hoping it's a little blip and he's going through an extended kind of dead-arm period, where he just doesn't have the [velocity]. He's a smart pitcher, and there's no reason to believe he's not going to get it back."

• D-backs left fielder Jason Kubel was out of the starting lineup on Saturday, one day after feeling discomfort in his right hamstring while slipping on the wet field.

While the injury is not believed to be serious, it also hadn't improved a lot since Friday and the D-backs plan to be extremely cautious with him.
