The 29-year-old had spent his entire professional career with the Baltimore Orioles, posting a 5.57 ERA, 1.46 WHIP, and 126/36 K/BB ratio in 158 1/3 MLB innings. He's actually the perfect pitcher for the Brewers. Zimmermann throws five pitches at least 10 percent of the time with good command of each one. It just happens that none of them really miss bats. However, the Brewers were able to get the most out of pitchers like Tobias Myers, who have a similar profile, and might be able to do the same for Zimmermann.
