Hyun Jin Ryu was a starting pitcher for the Toronto Blue Jays. In 2023 he struck out 38 batters over 52.0 innings across 11 appearances, 11 of them starts, going 3-3. His ERA of 3.46 was 20.1% lower than the league average of 4.33 — 7th of 16 on his team, and 146th of 550 among MLB pitchers with 20+ innings. Stripping out defence, his 4.91 FIP suggests that his ERA had some help behind him. He missed bats on 21.1% of swings (10.1% of every pitch he threw), walked 6.3% of the batters he faced and struck out 17.0%. His 0.3 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.

Hyun Jin Ryu'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.
