Jonah Tong is a starting pitcher for the New York Mets. In 2026 he struck out 34 batters over 30.2 innings across 7 appearances, 4 of them starts, going 2-2. His ERA of 3.82 was 8.8% lower than the league average of 4.18 — 9th of 22 on his team, and 228th of 539 among MLB pitchers with 20+ innings. Stripping out defence, his 3.30 FIP suggests he pitched better than his ERA shows. He missed bats on 30.2% of swings (14.8% of every pitch he threw), walked 10.4% of the batters he faced and struck out 25.4%. His 0.6 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.
