Jake Alu is a left fielder for the Washington Nationals. In 2023 he hit 2 home runs and knocked in 16 RBIs, notching 36 hits across 175 plate appearances in 50 games. His batting average was .226, 8.8% lower than the league average of .248. He reached base at a .282 clip and slugged .289, for an OPS of .571, 22.2% lower than the league mark of .734 — the worst on his team, and 419th of 461 among MLB batters with 100+ plate appearances. He averaged 87.8 mph off the bat, hit 33.6% of balls in play at 95 mph or better, barrelled 1.7% of them and made contact on 73.5% of his swings. Adjusted for his ballpark and league, his 56 wRC+ puts his offence 44% below average. That comes to -0.4 dbWAR — -9.2 runs with the bat, +0.2 on the bases, -0.6 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.
