Kyle Backhus is a relief pitcher for the Philadelphia Phillies. In 2026 he struck out 20 batters over 20.0 innings across 21 appearances, going 2-1. His ERA of 4.95 is 18.5% higher than the league average of 4.18 — 10th of 17 on his team, and 403rd of 538 among MLB pitchers with 20+ innings. Stripping out defence, his 4.25 FIP suggests he pitched better than his ERA shows. He missed bats on 19.6% of swings (8.5% of every pitch he threw), walked 6.4% of the batters he faced and struck out 21.3%. 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.

Kyle Backhus'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.
