Blake Treinen is a relief pitcher for the Los Angeles Dodgers. In 2026 he struck out 25 batters over 23.0 innings across 29 appearances, going 4-1. His ERA of 3.52 was 15.7% lower than the league average of 4.18 — 9th of 15 on his team, and 171st of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 3.48 FIP suggests the ERA was no fluke. He missed bats on 25.7% of swings (12.3% of every pitch he threw), walked 10.0% of the batters he faced and struck out 25.0%. His 0.3 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.
