The Brewers reinstated Zastrzyny (shoulder/ribs) from the 60-day injured list Sunday.
After spending the first couple months of the season on the shelf due to shoulder and intercostal strains, Zastryzny is ready to join the Brewers after six scoreless rehab appearances. The left-hander covered a career-high 22 frames in the majors last year and had a 2.45 ERA, 1.18 WHIP and 20:10 K:BB.
