Hyeon-Jong Yang was a relief pitcher for the Texas Rangers. In 2021 he struck out 25 batters over 35.1 innings across 12 appearances, going 0-3. His ERA of 5.60 was 31.4% higher than the league average of 4.27 — 19th of 22 on his team, and 456th of 567 among MLB pitchers with 20+ innings. Stripping out defence, his 6.51 FIP suggests that his ERA had some help behind him. He missed bats on 20.1% of swings (10.0% of every pitch he threw), walked 10.0% of the batters he faced and struck out 15.6%. 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.
