Guillermo Moscoso was a relief pitcher for the San Francisco Giants. In 2013 he struck out 31 batters over 30.0 innings across 13 appearances, going 2-2. His ERA of 5.10 was 31.9% higher than the league average of 3.87 — 15th of 18 on his team, and 405th of 496 among MLB pitchers with 20+ innings. Stripping out defence, his 5.55 FIP suggests that his ERA had some help behind him. He missed bats on 27.5% of swings (11.7% of every pitch he threw), walked 16.4% of the batters he faced and struck out 24.2%. His -0.4 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.

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.
