Jahmai Jones is a designated hitter for the Detroit Tigers. So far in 2026 he has hit 6 home runs and knocked in 16 RBIs, notching 33 hits across 179 plate appearances in 92 games. His batting average is .209, 14.4% lower than the league average of .244. He reached base at a .302 clip and slugged .373, for an OPS of .675, 6.0% lower than the league mark of .719 — 12th of 18 on his team, and 284th of 462 among MLB batters with 100+ plate appearances. He averaged 90.6 mph off the bat, hit 44.4% of balls in play at 95 mph or better, barrelled 10.1% of them and made contact on 65.2% of his swings. Adjusted for his ballpark and league, his 92 wRC+ puts his offence 8% below average. That comes to -0.0 dbWAR — -2.1 runs with the bat, +0.2 for the ballpark, -0.5 on the bases, +0.2 on double plays, -3.5 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.
