Yasuhiko Yabuta was a relief pitcher for the Kansas City Royals. In 2009 he struck out 9 batters over 14.0 innings across 12 appearances, going 2-1. His ERA of 13.50 was 212.4% higher than the league average of 4.32. Stripping out defence, his 6.10 FIP suggests he pitched better than his ERA shows. He missed bats on 19.1% of swings (7.7% of every pitch he threw), walked 9.1% of the batters he faced and struck out 11.7%. 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.

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.
