Jakob Junis is a relief pitcher for the Texas Rangers. In 2026 he struck out 37 batters over 53.0 innings across 51 appearances, going 1-3. His ERA of 3.57 is 14.6% lower than the league average of 4.18 — 4th of 16 on his team, and 175th of 538 among MLB pitchers with 20+ innings. Stripping out defence, his 3.82 FIP suggests the ERA was no fluke. He missed bats on 18.1% of swings (8.4% of every pitch he threw), walked 6.6% of the batters he faced and struck out 16.4%. His 0.5 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.

How these are computed

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.
