Snake bites

• Outfielder Jason Kubel has been nursing a sore left quad and was held out of the lineup once again on Friday.

"We've been trying to get it to resolve," manager Kirk Gibson said. "He can run, but I don't think he was moving too good when he was running the bases. It's kind of finicky. Some days it's OK, some days it's not. He hasn't really had resolution on it."

Kubel initially injured the quad in early April and spent two weeks on the disabled list last month as a result.

"When I came back from the DL, it was completely gone, it wasn't there and I had no limitations," Kubel said. "But I think a week into it, I dove for a ball and it kind of came back."

• Outfielder Adam Eaton started in center for Class A Visalia on Friday, the first time he has played in the field since injuring his throwing elbow this spring. Eaton had been serving as the designated hitter.

• Heading into Friday's game, eight of the past nine D-backs games had been decided by two runs or less and the team went 6-2 in those contests.
