Aaron Ashby is a relief pitcher for the Milwaukee Brewers. In 2026 he struck out 116 batters over 89.1 innings across 75 appearances, going 13-3. His ERA of 3.12 was 25.3% lower than the league average of 4.18 — 7th of 15 on his team, and 108th of 539 among MLB pitchers with 20+ innings. Stripping out defence, his 3.11 FIP suggests the ERA was no fluke. He missed bats on 32.2% of swings (13.1% of every pitch he threw), walked 10.7% of the batters he faced and struck out 30.3%. His 1.7 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.
