Rest-of-Season Projections
Signed a one-year contract with the Yankees in February of 2025. Traded to the Brewers in May of 2025.
Pulled off rehab assignment
The Brewers returned Zastryzny from his rehab assignment with Triple-A Nashville after he suffered a setback in his recovery from a rib injury, Adam McCalvy of MLB.com reports.
Analysis
Zastryzny made two rehab appearances with Nashville, yielding a total of four runs on four hits and two walks over 1.2 innings. The lefty has been out since late June with a rib stress reaction, and his return from the 15-day injured list doesn't appear to be imminent after he was unable to complete the rehab assignment. He's scheduled to undergo further imaging on his rib before the Brewers determine his next steps.

2017 Fantasy Outlook
Zastryzny spent much of 2016 in the minors before emerging as a fairly reliable long-relief and lefty specialist during the Cubs' playoff push. He made his debut on Aug. 19 and would go on to post a 1.13 ERA in 11 appearances while also making Chicago’s NLDS and NLCS roster. Zastryzny had fairly extreme platoon splits, as lefties only hit for a .138 BA against him while righties hit .276. Righties also slugged .310 versus Zastryzny while lefties only slugged .138. While his impressive 2016 numbers will likely regress somewhat with a larger sample size, Zastryzny appears to have solidified a role in Chicago's pen next year. In addition to being a lefty-specialist, he also has long-relief capability and while Mike Montgomery will likely get the first crack at filling in Jason Hammel's spot in the rotation, the 24-year-old will also get a chance in spring training to make his case to be the Cubs' fifth starter.
