J.D. Martinez is a designated hitter for the New York Mets. In 2024 he hit 16 home runs and knocked in 69 RBIs, notching 102 hits across 495 plate appearances in 120 games. His batting average was .235, 3.4% lower than the league average of .243. He reached base at a .320 clip and slugged .406, for an OPS of .725, 2.0% higher than the league mark of .711 — 6th of 15 on his team, and 165th of 455 among MLB batters with 100+ plate appearances. He averaged 91.0 mph off the bat, hit 46.3% of balls in play at 95 mph or better, barrelled 12.9% of them and made contact on 68.5% of his swings. Adjusted for his ballpark and league, his 107 wRC+ puts his offence 7% above average. That comes to 0.5 dbWAR — +3.5 runs with the bat, -0.9 on the bases, -14.4 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.
