Montas is scheduled to make his first start with the Brewers on Friday against the Nationals in Washington, Adam McCalvy of MLB.com reports.
The right-hander was acquired from Cincinnati on Monday, and he'll get a few days to settle in for his new team before debuting this weekend. Montas hasn't been particularly effective this season with a 5.01 ERA, 1.44 WHIP and 78:41 K:BB over 93.1 innings, but in recent years, the Brewers have been one of the better teams in the majors when it comes to getting the most out of their pitchers.
