Wily Mo Peña was a designated hitter for the Seattle Mariners. In 2011 he hit 7 home runs and knocked in 15 RBIs, notching 23 hits across 120 plate appearances in 38 games. His batting average was .204, 20.2% lower than the league average of .255. He reached base at a .250 clip and slugged .416, for an OPS of .666, 7.5% lower than the league mark of .720 — 7th of 18 on his team, and 301st of 452 among MLB batters with 100+ plate appearances. He made contact on 62.3% of his swings. Adjusted for his ballpark and league, his 86 wRC+ puts his offence 14% below average. That comes to -0.2 dbWAR — -2.3 runs with the bat, +0.2 for the ballpark, -0.1 on the bases, +0.1 on double plays, -2.7 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.

Runners on includes runners in scoring position, which is the convention every reference uses. Rows under 25 plate appearances are marked thin — at that size a rate moves several dozen points on one hit. Counted from play-by-play, 2011.

Not in the 2011 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.
