Jonah Tong is a relief pitcher for the New York Mets. In 2026 he struck out 25 batters over 25.2 innings across 6 appearances, going 2-2. His ERA of 4.21 is 0.7% higher than the league average of 4.18 — 11th of 22 on his team, and 296th of 538 among MLB pitchers with 20+ innings. Stripping out defence, his 3.80 FIP suggests he pitched better than his ERA shows. He missed bats on 26.9% of swings (13.5% of every pitch he threw), walked 11.4% of the batters he faced and struck out 21.9%. 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.
