Blake Treinen is a relief pitcher for the Los Angeles Dodgers. In 2026 he struck out 31 batters over 29.2 innings across 36 appearances, going 4-1. His ERA of 3.64 is 12.9% lower than the league average of 4.18 — 11th of 18 on his team, and 190th of 538 among MLB pitchers with 20+ innings. Stripping out defence, his 3.74 FIP suggests the ERA was no fluke. He missed bats on 24.9% of swings (11.9% of every pitch he threw), walked 10.0% of the batters he faced and struck out 23.8%. 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.
