Mason Adams is a starting pitcher for the Colorado Rockies. In 2026 he struck out 23 batters over 23.0 innings across 5 appearances, 5 of them starts, going 0-1. His ERA of 5.09 is 21.5% higher than the league average of 4.19 — 5th of 20 on his team, and 402nd of 527 among MLB pitchers with 20+ innings. Stripping out defence, his 6.19 FIP suggests that his ERA had some help behind him. He missed bats on 18.9% of swings (8.8% of every pitch he threw), walked 11.9% of the batters he faced and struck out 22.8%. 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.
