Adrián Martinez was a relief pitcher for the Oakland Athletics. In 2023 he struck out 47 batters over 55.0 innings across 22 appearances, going 0-2. His ERA of 4.75 was 9.6% higher than the league average of 4.33 — 9th of 18 on his team, and 365th of 550 among MLB pitchers with 20+ innings. Stripping out defence, his 4.75 FIP suggests the ERA was no fluke. He missed bats on 23.1% of swings (10.5% of every pitch he threw), walked 7.9% of the batters he faced and struck out 19.5%. His 0.1 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.

Adrián Martinez'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.
