2026 Projections
2026 Fantasy Outlook
Although Zerpa was deployed in the rotation during the minors, he primarily served out of the Royals' bullpen following his major-league debut in 2021. He made just two starts during the 2025 campaign and finished with a 4.18 ERA, 1.38 WHIP, 14 holds and a 58:22 K:BB across 64.2 innings. Zerpa was traded to the Brewers in December, and there is an openness to have the 26-year-old southpaw work out of Milwaukee's rotation in 2026. That'll ultimately depend on whether he is fully stretched out during spring training, though he wouldn't provide much fantasy value in strikeouts given his extremely low whiff rate (16.4 percent) and below average chase rate (26.7 percent). That said, Zerpa's 63.7 percent groundall rate ranked in the top one percentile in the majors in 2025, which could translate nicely into low ERA and WHIP numbers in a relief or starting role.
