Mason Miller is a relief pitcher for the San Diego Padres. In 2026 he struck out 129 batters over 70.0 innings across 66 appearances, going 5-2. His ERA of 1.67 was 60.0% lower than the league average of 4.18 — the best on his team, and 7th of 539 among MLB pitchers with 20+ innings. Stripping out defence, his 1.17 FIP suggests he pitched better than his ERA shows. He missed bats on 45.3% of swings (21.4% of every pitch he threw), walked 9.6% of the batters he faced and struck out 47.4%. His 2.8 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.

Box-score and rate statistics only. wOBA, wRC+, FIP and dbWAR are measured against a full league season, and a postseason is a few teams playing each other for a month, so they are not computed for October.
