Right-handed pitcher Kyle Lohse will miss his next start because of elbow soreness, Milwaukee Brewers manager Ron Roenicke said Wednesday.

His place in the rotation Saturday vs. Pittsburgh will be taken by Mike Fiers, a starter last season who is working out of the bullpen this year. Fiers was part of the very effective five-man bullpen effort Tuesday night against the Dodgers.

Roenicke said Lohse's elbow is not serious and that Lohse would take his turn after skipping this start.

"He didn't seem concerned about it," Roenicke said. "We're hoping it's not a big deal."

Fiers, who was a pleasant surprise last season as a rookie, was sent to the minors shortly after the season began and then recalled to strengthen the bullpen.

"Hopefully this will get him back to the way he was the last couple of years," Roenicke said. "(Tuesday night) was huge for him. We'll see how he does."

Starting concerns: As good as the Brewers' bullpen has been lately, Roenicke mentioned the obvious before the 9-2 loss to the Dodgers.

"I don't think we can get by with five innings from our starters," he said.

And it got worse Wednesday when Wily Peralta did not make it out of the second inning.

The three starters Roenicke counted on — Yovani Gallardo, Marco Estrada and Lohse — have not performed the way the Brewers have hoped. That leaves them with two young pitchers at the bottom of the rotation, Hiram Burgos and Peralta.
