Worth noting

• After a red hot spring, third baseman Martin Prado was hitting just .120 after the D-backs dropped three of four this week to the Giants, but manager Kirk Gibson wasn't going to take him out of the cleanup spot.

"I'm not going to overthink that," Gibson said. "I put him there for a reason. I believe in him and I want him to know that I do. I feel confident that he's fine. The numbers don't show he's fine, but he's fine. We didn't lose that series because Prado didn't do his job in the four-hole. I think he had good at-bats. They didn't fall for him. Guys made some decent plays on him."

• Gibson said that he has yet to decide who will primarily serve as the team's eighth-inning setup man. Will Harris pitched in the role twice in the Giants series, and he was effective the first time before allowing five runs in the eighth inning on Thursday.

"We're just kind of finding our way into roles," Gibson said. "Hopefully we'll get into a rhythm here. You need your starters to go six innings, for sure. You get them doing that, then it kind of makes it a lot easier to manage your bullpen and give guys more defined roles."

David Hernandez had been pegged to fill the setup role, but he had season-ending Tommy John surgery this week.

• Outfielder Cody Ross went 2-for-2 with an RBI while playing five innings in left field for Triple-A Reno on Thursday night.

It was Ross' first rehab game. He is expected to be with Reno anywhere from seven to 10 days.
