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 was 12.9% lower than the league average of 4.18 — 11th of 18 on his team, and 187th of 539 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.

Blake Treinen's arsenal by usage. Velocity is average release speed in mph, spin in rpm, and whiff rate is misses per swing — the cleanest single measure of whether a pitch beats hitters. BAA and OPS are what hitters did against each pitch, credited to the one that ended the plate appearance, and are left blank under 15 at-bats.

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.
