Gerardo Parra is a left fielder for the Washington Nationals. In 2021 he hit 2 home runs and knocked in 10 RBIs, notching 23 hits across 107 plate appearances in 51 games. His batting average was .237, 2.7% lower than the league average of .244. He reached base at a .292 clip and slugged .351, for an OPS of .643, 11.7% lower than the league mark of .728 — 17th of 20 on his team, and 355th of 463 among MLB batters with 100+ plate appearances. He averaged 86.9 mph off the bat, hit 29.0% of balls in play at 95 mph or better, barrelled 1.4% of them and made contact on 73.9% of his swings. Adjusted for his ballpark and league, his 78 wRC+ puts his offence 22% below average. That comes to -0.1 dbWAR — -3.0 runs with the bat, -0.3 on the bases, -1.6 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.

A barrel is a batted ball whose exit velocity and launch angle have historically produced at least a .500 average and 1.500 slugging — 98 mph within 26–30°, widening to 8–50° by 116 mph. Reconstructed from Statcast's published anchor points, which reproduces them exactly; the interior is within a degree. Sweet spot (8–32°) is an exact definition.

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.
