"It's getting there," Counsell said. "We're going to have to have those conversations. But we haven't as of yet."
Peralta threw 74 pitches and allowed one run on three hits, with a walk and five strikeouts. The Brewers could bring him back to start during the team's upcoming road trip to Arizona and San Francisco, or leave him in the Minors for one more outing, buying time to figure out how to fit him into a crowded starting rotation.
Opening a spot for Peralta could be complicated. Rookie right-hander Taylor Jungmann is 5-1 with a 2.04 ERA since being recalled from Triple-A, and it is difficult to see the Brewers sending him back down. Likewise, Mike Fiers has a 2.25 ERA in July, and Jimmy Nelson has a 3.32 ERA for the month. Both are earning salaries near the minimum and are considered part of the Brewers' future.
That leaves veterans Matt Garza and Kyle Lohse. Garza returned from the disabled list to start against the Indians on Tuesday and pitched six scoreless innings to lower his ERA to 5.23. He's signed for two more seasons, and would be difficult to move. Lohse, a free agent at season's end, is 5-10 with a 6.17 ERA entering his Wednesday start against the Indians.
If the Brewers give Peralta one more Minor League start to build up his pitch count, it would bide some time.
"That's what we have to figure out," Counsell said.
