Jack Dreyer is a relief pitcher for the Los Angeles Dodgers. In 2026 he struck out 54 batters over 47.0 innings across 48 appearances, going 4-1. His ERA of 2.87 was 31.2% lower than the league average of 4.18 — 5th of 15 on his team, and 94th of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 3.34 FIP suggests that his ERA had some help behind him. He missed bats on 28.4% of swings (13.8% of every pitch he threw), walked 7.1% of the batters he faced and struck out 29.3%. His 0.7 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.

How these are computed

wOBA uses linear weights measured from this season's own play-by-play rather than published constants, and wRC+ is park-adjusted against that same league. dbWAR is our own open implementation — not fWAR or bWAR — and the full derivation, including its simplifications, is on the methodology page.
