Seby Zavala is a catcher for the Seattle Mariners. In 2024 he hit 1 home run and knocked in 2 RBIs, notching 6 hits across 43 plate appearances in 16 games. His batting average was .154, 36.8% lower than the league average of .243. He reached base at a .214 clip and slugged .282, for an OPS of .496, 30.2% lower than the league mark of .711. He averaged 88.0 mph off the bat, hit 41.7% of balls in play at 95 mph or better, barrelled 4.2% of them and made contact on 63.1% of his swings. Adjusted for his ballpark and league, his 39 wRC+ puts his offence 61% below average. That comes to -0.1 dbWAR — -3.2 runs with the bat, -0.0 on the bases, +0.9 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.

A barrel is a batted ball whose exit velocity and launch angle have historically produced at least a .500 average and 1.500 slugging — 98 mph within 26–30°, widening to 8–50° by 116 mph. Reconstructed from Statcast's published anchor points, which reproduces them exactly; the interior is within a degree. Sweet spot (8–32°) is an exact definition.

How these are computed

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.
