Robert Gasser is a starting pitcher for the Milwaukee Brewers. In 2026 he struck out 103 batters over 109.1 innings across 21 appearances, 20 of them starts, going 5-5. His ERA of 3.87 was 7.5% lower than the league average of 4.18 — 10th of 15 on his team, and 241st of 539 among MLB pitchers with 20+ innings. Stripping out defence, his 4.24 FIP suggests that his ERA had some help behind him. He missed bats on 22.5% of swings (11.1% of every pitch he threw), walked 7.6% of the batters he faced and struck out 22.2%. His 1.2 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.

Robert Gasser'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.
