Ryan Borucki is a relief pitcher for the San Francisco Giants. In 2026 he struck out 15 batters over 23.2 innings across 21 appearances, going 1-1. His ERA of 4.94 was 18.2% higher than the league average of 4.18 — 21st of 25 on his team, and 398th of 539 among MLB pitchers with 20+ innings. Stripping out defence, his 4.88 FIP suggests the ERA was no fluke. He missed bats on 28.2% of swings (13.9% of every pitch he threw), walked 8.7% of the batters he faced and struck out 14.4%. 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.

Ryan Borucki'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.
