Walter Silva was a starting pitcher for the San Diego Padres. In 2009 he struck out 11 batters over 24.2 innings across 6 appearances, 6 of them starts, going 0-2. His ERA of 8.76 was 102.6% higher than the league average of 4.32 — the worst on his team, and 478th of 484 among MLB pitchers with 20+ innings. Stripping out defence, his 6.14 FIP suggests he pitched better than his ERA shows. He missed bats on 15.2% of swings (6.6% of every pitch he threw), walked 12.4% of the batters he faced and struck out 9.1%. His -0.3 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.

Walter Silva's arsenal by usage. Velocity is average release speed in mph, spin in rpm, and whiff rate is misses per swing — the cleanest single measure of whether a pitch beats hitters. BAA and OPS are what hitters did against each pitch, credited to the one that ended the plate appearance, and are left blank under 15 at-bats.

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.
