Humberto Mejía is a pitcher for the Arizona Diamondbacks. In 2021 he hit 0 home runs and knocked in 0 RBIs, notching 1 hit across 8 plate appearances in 5 games. His batting average was .143, 41.4% lower than the league average of .244. He reached base at a .143 clip and slugged .286, for an OPS of .429, 41.1% lower than the league mark of .728. He averaged 71.2 mph off the bat, hit 16.7% of balls in play at 95 mph or better and made contact on 77.3% of his swings. Adjusted for his ballpark and league, his 4 wRC+ puts his offence 96% below average. That comes to -0.1 dbWAR — -0.9 runs with the bat, +0.0 on the bases, +0.0 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.

Head to head
Put Humberto Mejía 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.
