Brandon Williamson is a starting pitcher for the Cincinnati Reds. In 2026 he struck out 19 batters over 28.0 innings across 6 appearances, 6 of them starts, going 2-3. His ERA of 6.11 was 46.3% higher than the league average of 4.18 — the second worst on his team, and 422nd of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 6.05 FIP suggests the ERA was no fluke. He missed bats on 24.1% of swings (10.4% of every pitch he threw), walked 15.6% of the batters he faced and struck out 14.8%. 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.
