Zack Greinke was a starting pitcher for the Kansas City Royals. In 2023 he struck out 97 batters over 142.1 innings across 30 appearances, 27 of them starts, going 2-15. His ERA of 5.06 was 16.8% higher than the league average of 4.33 — 14th of 23 on his team, and 407th of 550 among MLB pitchers with 20+ innings. Stripping out defence, his 4.74 FIP suggests he pitched better than his ERA shows. He missed bats on 17.3% of swings (8.1% of every pitch he threw), walked 3.9% of the batters he faced and struck out 16.4%. His 1.1 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.

Opponent batting by the side the hitter bats from, 2023. Counted from play-by-play, so totals can differ from the box-score season line by a plate appearance or two.

Zack Greinke'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.
