Will Klein is a relief pitcher for the Los Angeles Dodgers. In 2026 he struck out 49 batters over 41.2 innings across 36 appearances, going 3-4. His ERA of 3.67 was 12.2% lower than the league average of 4.18 — 13th of 18 on his team, and 200th of 539 among MLB pitchers with 20+ innings. Stripping out defence, his 3.42 FIP suggests the ERA was no fluke. He missed bats on 23.9% of swings (10.4% of every pitch he threw), walked 11.1% of the batters he faced and struck out 25.9%. His 0.6 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.

Box-score and rate statistics only. wOBA, wRC+, FIP and dbWAR are measured against a full league season, and a postseason is a few teams playing each other for a month, so they are not computed for October.
