Carmen Mlodzinski is a relief pitcher for the Pittsburgh Pirates. In 2026 he struck out 97 batters over 123.0 innings across 37 appearances, going 8-7. His ERA of 3.95 was 5.5% lower than the league average of 4.18 — 8th of 15 on his team, and 257th of 539 among MLB pitchers with 20+ innings. Stripping out defence, his 3.75 FIP suggests the ERA was no fluke. He missed bats on 20.9% of swings (9.4% of every pitch he threw), walked 8.2% of the batters he faced and struck out 18.1%. 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.

Carmen Mlodzinski'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.
