Jonah Heim is a catcher for the Athletics. In 2026 he hit 13 home runs and knocked in 43 RBIs, notching 73 hits across 390 plate appearances in 105 games. His batting average was .204, 16.4% lower than the league average of .244. He reached base at a .262 clip and slugged .366, for an OPS of .627, 12.7% lower than the league mark of .719 — 14th of 17 on his team, and 364th of 465 among MLB batters with 100+ plate appearances. He averaged 87.3 mph off the bat, hit 32.4% of balls in play at 95 mph or better, barrelled 5.2% of them and made contact on 78.7% of his swings. Adjusted for his ballpark and league, his 63 wRC+ puts his offence 37% below average. That comes to -0.3 dbWAR — -13.5 runs with the bat, -2.8 for the ballpark, -0.4 on the bases, -1.5 on double plays, +3.0 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.

Contact rate78.7%

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.
