Mason Adams is a starting pitcher for the Colorado Rockies. In 2026 he struck out 31 batters over 29.0 innings across 6 appearances, 6 of them starts, going 0-2. His ERA of 4.03 was 3.5% lower than the league average of 4.18 — 4th of 21 on his team, and 272nd of 539 among MLB pitchers with 20+ innings. Stripping out defence, his 5.00 FIP suggests that his ERA had some help behind him. He missed bats on 22.2% of swings (10.5% of every pitch he threw), walked 9.7% of the batters he faced and struck out 25.0%. His 0.1 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.
