Juan Morillo is a relief pitcher for the Arizona Diamondbacks. In 2026 he struck out 56 batters over 47.1 innings across 51 appearances, going 3-4. His ERA of 2.47 was 40.8% lower than the league average of 4.18 — the third best on his team, and 47th of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 2.41 FIP suggests the ERA was no fluke. He missed bats on 32.0% of swings (15.7% of every pitch he threw), walked 8.5% of the batters he faced and struck out 29.6%. His 1.2 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.

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.
