Jacob Lopez is a starting pitcher for the Athletics. In 2026 he struck out 70 batters over 75.0 innings across 18 appearances, 15 of them starts, going 5-4. His ERA of 5.64 was 35.1% higher than the league average of 4.18 — 12th of 16 on his team, and 404th of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 5.31 FIP suggests he pitched better than his ERA shows. He missed bats on 23.9% of swings (10.7% of every pitch he threw), walked 12.5% of the batters he faced and struck out 20.3%. His -0.3 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.
