DETROIT -- Minutes before the start of Wednesday's game against the Tigers, the Brewers scratched left-hander Chris Capuano with a strained left groin and right-hander Carlos Villanueva began to warm-up.

The team did not specify how Capuano suffered the injury, but it apparently happened after he began warming up in the bullpen at Comerica Park.

The Brewers had lost each of Capuano's last six starts and he was 0-5 with a 6.89 ERA in that span. When Villanueva took the mound, it ended Milwaukee's distinction as the only Major League team to use only five starting pitchers this season.

Villanueva, who won a spot in the bullpen during Spring Training, entered the game 5-0 this season with a 3.00 ERA in 26 relief appearances. He last pitched two innings at Texas on Sunday, earning the win.
