Luke Jackson was a relief pitcher for the Texas Rangers. In 2025 he struck out 38 batters over 51.0 innings across 52 appearances, going 2-5. His ERA of 4.06 was 2.4% lower than the league average of 4.16 — 12th of 15 on his team, and 284th of 542 among MLB pitchers with 20+ innings. Stripping out defence, his 4.49 FIP suggests that his ERA had some help behind him. He missed bats on 22.7% of swings (10.6% of every pitch he threw), walked 12.8% of the batters he faced and struck out 17.4%. His 0.0 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.

Box-score and rate statistics only. wOBA, wRC+, FIP and dbWAR are measured against a full league season, and a postseason is a few teams playing each other for a month, so they are not computed for October.

Luke Jackson'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.
