ATLANTA (AP) -- Milwaukee ace Ben Sheets is questionable for his next start Sunday because of a strained left hamstring.
Sheets (12-5, 3.82 ERA) left Tuesday night's game in Houston after one inning.
The team says an MRI exam found a mild strain.
Sheets rejoined the club for its four-game series in Atlanta to undergo treatment.
Manager Ned Yost said Sheets was "50-50" to make his next start, the last game of the series in Atlanta.
If Sheets can't go, the Brewers likely would start either Claudio Vargas or Chris Capuano.
Vargas relieved Sheets against the Astros and pitched four scoreless innings in Milwaukee's 9-1 win.
