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.

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.
