Bryan Petersen was a left fielder for the Miami Marlins. In 2012 he hit 0 home runs and knocked in 17 RBIs, notching 47 hits across 273 plate appearances in 80 games. His batting average was .195, 23.4% lower than the league average of .255. He reached base at a .272 clip and slugged .257, for an OPS of .530, 26.9% lower than the league mark of .724 — 17th of 19 on his team, and 434th of 459 among MLB batters with 100+ plate appearances. He made contact on 79.9% of his swings. Adjusted for his ballpark and league, his 49 wRC+ puts his offence 51% below average. That comes to -1.0 dbWAR — -15.8 runs with the bat, -0.0 for the ballpark, +0.5 on the bases, +0.6 on double plays, -1.7 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.

Pitch arsenal

What he throws, how hard, how often it misses, and what hitters do with it.

Four-Seam Fastball55.6%1089.61,86950.0%0.0%2——
Bryan Petersen'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.

Not in the 2012 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.
