Josh Naylor is a first baseman for the Seattle Mariners. In 2026 he hit 10 home runs and knocked in 42 RBIs, notching 113 hits across 474 plate appearances in 111 games. His batting average was .263, 7.8% higher than the league average of .244. He reached base at a .328 clip and slugged .372, for an OPS of .700, 2.7% lower than the league mark of .719 — 7th of 15 on his team, and 218th of 417 among MLB batters with 100+ plate appearances. He averaged 87.4 mph off the bat, hit 36.7% of balls in play at 95 mph or better and made contact on 82.3% of his swings. Adjusted for his ballpark and league, his 99 wRC+ puts his offence 1% below average. That comes to 0.6 dbWAR — -2.2 runs with the bat, +1.8 on the bases, -9.9 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.
