Rafael Montero was a relief pitcher for the Atlanta Braves. In 2025 he struck out 58 batters over 60.1 innings across 59 appearances, going 1-2. His ERA of 4.48 was 7.6% higher than the league average of 4.16 — 14th of 17 on his team, and 348th of 542 among MLB pitchers with 20+ innings. Stripping out defence, his 4.13 FIP suggests he pitched better than his ERA shows. He missed bats on 29.3% of swings (13.8% of every pitch he threw), walked 14.6% of the batters he faced and struck out 22.9%. His 0.4 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.
