Riley Smith was a relief pitcher for the Arizona Diamondbacks. In 2021 he struck out 36 batters over 67.1 innings across 24 appearances, going 1-4. His ERA of 6.01 was 41.0% higher than the league average of 4.27 — 17th of 22 on his team, and 485th of 567 among MLB pitchers with 20+ innings. Stripping out defence, his 4.88 FIP suggests he pitched better than his ERA shows. He missed bats on 13.8% of swings (6.5% of every pitch he threw), walked 5.0% of the batters he faced and struck out 12.0%. His 0.1 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.
