Jeferson Quero is a catcher for the Milwaukee Brewers. In 2026 he hit 0 home runs and knocked in 0 RBIs, notching 0 hits across 2 plate appearances in 1 game. His batting average was .000, 100.0% lower than the league average of .244. He reached base at a .500 clip and slugged .000, for an OPS of .500, 30.5% lower than the league mark of .719. He averaged 85.6 mph off the bat and made contact on 50.0% of his swings. Adjusted for his ballpark and league, his 132 wRC+ puts his offence 32% above average. That comes to 0.0 dbWAR — +0.1 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 Jeferson Quero 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.
