Webster Rivas is a catcher for the San Diego Padres. In 2021 he hit 2 home runs and knocked in 4 RBIs, notching 15 hits across 77 plate appearances in 22 games. His batting average was .221, 9.5% lower than the league average of .244. He reached base at a .303 clip and slugged .338, for an OPS of .641, 12.0% lower than the league mark of .728. He averaged 84.8 mph off the bat, hit 32.1% of balls in play at 95 mph or better, barrelled 3.8% of them and made contact on 79.1% of his swings. Adjusted for his ballpark and league, his 82 wRC+ puts his offence 18% below average. That comes to 0.2 dbWAR — -1.9 runs with the bat, -0.1 on the bases, +1.6 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 Webster Rivas 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.
