Rob Zastryzny is a relief pitcher for the Milwaukee Brewers. In 2025 he struck out 20 batters over 22.0 innings across 26 appearances, going 2-1. His ERA of 2.45 was 41.0% lower than the league average of 4.16 — 4th of 17 on his team, and 52nd of 542 among MLB pitchers with 20+ innings. Stripping out defence, his 4.59 FIP suggests that his ERA had some help behind him. He missed bats on 31.8% of swings (15.7% of every pitch he threw), walked 10.8% of the batters he faced and struck out 21.5%. His 0.0 dbWAR is built from that FIP rather than runs allowed, so it credits him for what he controls and not for the defence behind him.
