Jonah Heim is a catcher for the Athletics. So far in 2026 he has hit 13 home runs and knocked in 43 RBIs, notching 73 hits across 387 plate appearances in 104 games. His batting average is .206, 15.7% lower than the league average of .244. He reached base at a .264 clip and slugged .369, for an OPS of .633, 12.0% lower than the league mark of .719 — 14th of 17 on his team, and 356th of 462 among MLB batters with 100+ plate appearances. He averaged 87.2 mph off the bat, hit 31.9% of balls in play at 95 mph or better, barrelled 5.2% of them and made contact on 78.8% of his swings. Adjusted for his ballpark and league, his 65 wRC+ puts his offence 35% below average. That comes to -0.2 dbWAR — -12.7 runs with the bat, -2.7 for the ballpark, -0.4 on the bases, -1.2 on double plays, +2.9 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.
