Jahmai Jones is a designated hitter for the Detroit Tigers. In 2026 he hit 4 home runs and knocked in 12 RBIs, notching 23 hits across 128 plate appearances in 69 games. His batting average was .198, 18.6% lower than the league average of .244. He reached base at a .273 clip and slugged .353, for an OPS of .627, 12.9% lower than the league mark of .719 — 11th of 15 on his team, and 338th of 417 among MLB batters with 100+ plate appearances. He averaged 90.8 mph off the bat, hit 45.2% of balls in play at 95 mph or better, barrelled 8.2% of them and made contact on 64.8% of his swings. Adjusted for his ballpark and league, his 74 wRC+ puts his offence 26% below average. That comes to -0.4 dbWAR — -4.0 runs with the bat, -0.4 on the bases, -3.4 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.
