Kaz Ishii was a starting pitcher for the New York Mets. In 2005 he struck out 53 batters over 91.0 innings across 19 appearances, 16 of them starts, going 3-9. His ERA of 5.14 was 19.9% higher than the league average of 4.29 — 12th of 15 on his team, and 323rd of 442 among MLB pitchers with 20+ innings. Stripping out defence, his 5.43 FIP suggests the ERA was no fluke. He missed bats on 20.8% of swings (9.0% of every pitch he threw), walked 12.3% 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.

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.
