PHOENIX -- When Wily Peralta started for Triple-A Nashville on Sunday, the Brewers' choice for their rotation vacancy became clear: Barring a last-minute change, it looks like right-hander Mike Fiers will pitch on Tuesday at Dodger Stadium.
The Brewers need a replacement starting that day for Marco Estrada, who went to the 15-day disabled list after straining his quadriceps last week in Milwaukee. The primary candidates were Peralta, Fiers or left-handed reliever Manny Parra, though manager Ron Roenicke has expressed a desire to preserve Parra's role in the bullpen.
On Sunday morning, Roenicke stopped short of officially naming Fiers his starter for Tuesday. If Fiers is the choice, he would be pitching on regular rest.
"We're going to need two starts for sure, we feel," Roenicke said. "We don't know how quickly Estrada is going to come; initially it was probably a little longer than just two starts, but he's coming along pretty good."
Fiers, who made two relief appearances for the Brewers in September, is 1-3 with a 4.42 ERA in 10 starts this season for Triple-A Nashville. The 26-year-old command specialist was a 22nd round Draft pick in 2009 and has a 2.80 ERA in four Minor League seasons, with 370 strikeouts vs. 91 walks in 346 2/3 innings.
Fiers would be the Brewers' seventh starting pitcher. In 2011, they used only six starters all year.
And general manager Doug Melvin remains on the lookout for more. The Milwaukee Journal Sentinel reported that the Brewers checked in on free agent Roy Oswalt but found his asking price too high for a half-season.
