Richard Fitts is a starting pitcher for the Boston Red Sox. In 2025 he struck out 40 batters over 45.0 innings across 11 appearances, 10 of them starts, going 2-4. His ERA of 5.00 was 20.2% higher than the league average of 4.16 — 14th of 16 on his team, and 411th of 542 among MLB pitchers with 20+ innings. Stripping out defence, his 5.80 FIP suggests that his ERA had some help behind him. He missed bats on 25.3% of swings (13.5% of every pitch he threw), walked 8.2% of the batters he faced and struck out 20.5%. 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.
