J.D. Martin was a starting pitcher for the Washington Nationals. In 2010 he struck out 31 batters over 48.0 innings across 9 appearances, 9 of them starts, going 1-5. His ERA of 4.13 was 1.1% higher than the league average of 4.08 — 12th of 20 on his team, and 244th of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 4.97 FIP suggests that his ERA had some help behind him. He missed bats on 14.4% of swings (6.1% of every pitch he threw), walked 5.2% of the batters he faced and struck out 14.6%. His 0.0 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.
