Ian Kennedy was a relief pitcher for the Texas Rangers. In 2023 he struck out 21 batters over 16.1 innings across 16 appearances, going 0-1. His ERA of 7.16 was 65.4% higher than the league average of 4.33. Stripping out defence, his 5.52 FIP suggests he pitched better than his ERA shows. He missed bats on 34.0% of swings (16.2% of every pitch he threw), walked 9.3% of the batters he faced and struck out 28.0%. 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.

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.

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.
