Josh Naylor is a first baseman for the Seattle Mariners. In 2026 he hit 10 home runs and knocked in 57 RBIs, notching 156 hits across 650 plate appearances in 152 games. His batting average was .261, 7.1% higher than the league average of .244. He reached base at a .317 clip and slugged .350, for an OPS of .667, 7.2% lower than the league mark of .719 — 9th of 16 on his team, and 300th of 465 among MLB batters with 100+ plate appearances. He averaged 86.8 mph off the bat, hit 35.8% of balls in play at 95 mph or better, barrelled 4.1% of them and made contact on 83.2% of his swings. Adjusted for his ballpark and league, his 90 wRC+ puts his offence 10% below average. That comes to 0.2 dbWAR — -10.5 runs with the bat, +1.5 for the ballpark, +1.3 on the bases, -2.5 on double plays, -8.1 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.

Contact rate83.2%

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.
