Mauricio Llovera is a relief pitcher for the Boston Red Sox. In 2023 he struck out 29 batters over 35.0 innings across 30 appearances, going 2-3. His ERA of 4.89 was 12.8% higher than the league average of 4.33 — 11th of 20 on his team, and 382nd of 550 among MLB pitchers with 20+ innings. Stripping out defence, his 4.34 FIP suggests he pitched better than his ERA shows. He missed bats on 17.7% of swings (7.6% of every pitch he threw), walked 9.4% of the batters he faced and struck out 18.1%. His 0.2 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.
