Grant Koch is a catcher for the Pittsburgh Pirates. In 2024 he hit 0 home runs and knocked in 0 RBIs, notching 0 hits across 8 plate appearances in 3 games. His batting average was .000, 100.0% lower than the league average of .243. He reached base at a .125 clip and slugged .000, for an OPS of .125, 82.4% lower than the league mark of .711. He averaged 89.1 mph off the bat and made contact on 64.3% of his swings. Adjusted for his ballpark and league, his -56 wRC+ puts his offence 156% below average. That comes to -0.1 dbWAR — -1.5 runs with the bat, -0.0 on the bases, +0.1 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.

Head to head
Put Grant Koch beside up to three others.
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.
