Matt Seelinger is a relief pitcher for the New York Mets. In 2026 he struck out 2 batters over 2.0 innings across 1 appearance, going 0-1. His ERA of 31.50 was 654.4% higher than the league average of 4.18. Stripping out defence, his 13.59 FIP suggests he pitched better than his ERA shows. He missed bats on 29.2% of swings (13.5% of every pitch he threw), walked 26.7% of the batters he faced and struck out 13.3%. 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.

Head to head
Put Matt Seelinger beside up to three others.
wOBA uses linear weights measured from this season's own play-by-play rather than published constants, and wRC+ is park-adjusted against that same league. dbWAR is our own open implementation — not fWAR or bWAR — and the full derivation, including its simplifications, is on the methodology page.
