Pollock returns to lineup, starts in left field

MILWAUKEE -- A.J. Pollock, held out of the starting lineup for five games, started in left field on Tuesday night against the Brewers rather than his customary center field spot to hopefully lessen the strain on his injured groin.

Rookie Ender Inciarte, who made his Major League debut on Friday, was in center field for the fifth consecutive game.

"That's one of the reasons. Pollo, he's been nursing that a lot. I think it kind of minimizes how far he's got to go," D-backs manager Kirk Gibson said before Tuesday night's game. "I think Pollo's probably going to be our center fielder. Inciarte can play anywhere, as well. But for right now, his first game back, I decided to put him out there."

Pollock, hitting .256 , grounded out as a pinch-hitter in Monday night's 8-3 loss to the Brewers and appeared as a pinch-runner on Sunday against San Diego, staying in to play left field for one inning.

Gibson unsure who will replace Bolsinger in rotation

MILWAUKEE -- With the demotion of right-hander Mike Bolsinger to Triple-A Reno on Tuesday, D-backs manager Kirk Gibson said he is not yet sure who will take his spot in the starting rotation.

"As far as a starter in Bolsinger's place, we really don't need to decide that until next Tuesday," Gibson said. "We'll just wait and see how we get through the next two days."

Bolsinger, who allowed four runs on seven hits in five innings in Monday's 8-3 loss to the Brewers, was 1-2 with a 6.08 ERA in five games, including four starts, with the D-backs

The D-backs have an off-day on Thursday, followed by a three-game series at the Chicago White Sox, before returning home on Monday against the Washington Nationals.

Josh Collmenter, who started Tuesday night's game against the Brewers, could start again on Sunday. Gibson added that Chase Anderson, called up from Double-A Mobile on Tuesday to take Bolsinger's roster spot, also could be an option.

"Colie could throw that game," Gibson said. "We really wouldn't need anybody until Tuesday. Or, we could put somebody else in there. We're considering our options."
