Akinori Iwamura was a second baseman for the Pittsburgh Pirates. In 2010 he hit 2 home runs and knocked in 13 RBIs, notching 34 hits across 229 plate appearances in 64 games. His batting average was .173, 32.6% lower than the league average of .257. He reached base at a .285 clip and slugged .250, for an OPS of .535, 26.5% lower than the league mark of .728 — the worst on his team, and 426th of 442 among MLB batters with 100+ plate appearances. He made contact on 78.2% of his swings. Adjusted for his ballpark and league, his 53 wRC+ puts his offence 47% below average. That comes to -0.5 dbWAR — -12.3 runs with the bat, -0.1 for the ballpark, +0.0 on the bases, -0.2 on double plays, +1.1 for the position he plays, against replacement level. It includes no fielding: defensive runs are proprietary and are not estimated here, so the figure credits playing a demanding position but not playing it well.

Not in the 2010 data: exit velocity and launch angle, first recorded in 2015. 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.
