Francisco Del Rosario was a relief pitcher for the Philadelphia Phillies. In 2007 he struck out 25 batters over 26.1 innings across 23 appearances, going 0-3. His ERA of 5.47 was 22.2% higher than the league average of 4.47 — 12th of 17 on his team, and 365th of 484 among MLB pitchers with 20+ innings. Stripping out defence, his 4.76 FIP suggests he pitched better than his ERA shows. He missed bats on 22.3% of swings (9.6% of every pitch he threw), walked 10.2% of the batters he faced and struck out 19.7%. 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 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.
