Akinori Otsuka was a relief pitcher for the Texas Rangers. In 2007 he struck out 23 batters over 32.1 innings across 34 appearances, going 2-1. His ERA of 2.51 was 44.0% lower than the league average of 4.47 — the best on his team, and 37th of 484 among MLB pitchers with 20+ innings. Stripping out defence, his 2.65 FIP suggests the ERA was no fluke. He missed bats on 20.7% of swings (9.6% of every pitch he threw), walked 6.9% of the batters he faced and struck out 17.6%. 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.

Box-score and rate statistics only. wOBA, wRC+, FIP and dbWAR are measured against a full league season, and a postseason is a few teams playing each other for a month, so they are not computed for October.

Not in the 2007 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.

How these are computed

wOBA uses linear weights measured from this season's own play-by-play rather than published constants, and wRC+ is park-adjusted against that same league. dbWAR is our own open implementation — not fWAR or bWAR — and the full derivation, including its simplifications, is on the methodology page.
