Shigetoshi Hasegawa was a relief pitcher for the Seattle Mariners. In 2005 he struck out 30 batters over 66.2 innings across 46 appearances, going 1-3. His ERA of 4.18 was 2.5% lower than the league average of 4.29 — 7th of 14 on his team, and 216th of 442 among MLB pitchers with 20+ innings. Stripping out defence, his 3.76 FIP suggests he pitched better than his ERA shows. He missed bats on 14.1% of swings (5.9% of every pitch he threw), walked 5.7% of the batters he faced and struck out 10.8%. His 0.8 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.

Not in the 2005 data: pitch types, recorded in every park from 2008. The play-by-play goes back to 2005, but the measurements on each pitch and batted ball arrived later, so the panels built from them are left off this season.
