Matt Mantei was a relief pitcher for the Boston Red Sox. In 2005 he struck out 22 batters over 26.1 innings across 34 appearances, going 1-0. His ERA of 6.49 was 51.3% higher than the league average of 4.29 — the second worst on his team, and 403rd of 442 among MLB pitchers with 20+ innings. Stripping out defence, his 5.15 FIP suggests he pitched better than his ERA shows. He missed bats on 16.7% of swings (6.5% of every pitch he threw), walked 19.2% of the batters he faced and struck out 17.6%. 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.

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.
