Mike Gerber is a left fielder for the San Francisco Giants. In 2019 he hit 0 home runs and knocked in 0 RBIs, notching 1 hit across 26 plate appearances in 9 games. His batting average was .042, 83.5% lower than the league average of .252. He reached base at a .115 clip and slugged .083, for an OPS of .199, 73.8% lower than the league mark of .758. He averaged 90.2 mph off the bat, hit 44.4% of balls in play at 95 mph or better, barrelled 11.1% of them and made contact on 41.9% of his swings. Adjusted for his ballpark and league, his -53 wRC+ puts his offence 153% below average. That comes to -0.4 dbWAR — -4.9 runs with the bat, -0.0 on the bases, -0.3 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 Mike Gerber 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.
