Josh Naylor Just Keeps Getting Better

There have always been fairly high expectations for Guardians first baseman Josh Naylor. He entered the 2015 draft considered one of the 60 or so best talents available and instead vaulted to the No. 12 overall selection when the Marlins took him and cut an under-slot deal with him, signing him for a $2.25MM bonus that clocked in shy of his $3.05MM slot value.

As if the draft stock wasn’t enough, Naylor was soon included in a pair of relatively high-profile trades. Miami sent him to the Padres alongside Carter Capps, Jarred Cosart and, ahem, Luis Castillo (whoops) in exchange for Andrew Cashner, Colin Rea and Tayron Guerrero. Naylor ranked among the game’s top-100 prospects heading into the 2019 season and made his debut with San Diego that season before being packaged with Owen Miller, Austin Hedges, Joey Cantillo, Gabriel Arias and Cal Quantrill to acquire Mike Clevinger, Greg Allen and Matt Waldron from Cleveland (again… whoops).

For the first three seasons of Naylor’s career, he was an up-and-down first baseman/outfielder/designated hitter who didn’t do much hitting. In his first 633 plate appearances, he posted an anemic .250/.306/.389 batting line (88 wRC+). His 19.1% strikeout rate was lower than the league average, but so was his 7% walk rate. Naylor hit the ball on the ground at a huge 51.6% clip, which is far from ideal for a hitter who drew 20- and 30-grade marks for his speed as a prospect. He was borderline passive at the dish, only swinging at 48% of pitches thrown.

In what amounted to roughly a full season’s worth of plate appearances (603) over that three-year span, Naylor was more or less a replacement-level player. He made plenty of contact but didn’t do much damage with it and didn’t really contribute defensively. Naylor posted below-average grades from both Defensive Runs Saved and Outs Above Average in the outfield corners and only saw sparse action at first base (106 innings).

In 2022, the Guardians moved Naylor to first base full time. Whether he felt more comfortable there and thus at the plate, or whether he simply adapted to big league pitching after getting a few hundred plate appearances under his belt, a corner was clearly turned. Naylor took a huge step forward at the dish, smacking a career-best 20 homers while hitting .256/.319/.452 in 498 plate appearances. His walk rate crept up from 5.6% to 7.6% His strikeout rate dipped from 18% to 16.1%. Things continued trending in a positive direction in 2023, with Naylor cutting the strikeout rate all the way to 13.7% as he turned in an even better .308/.354/.489 slash.

This season, Naylor’s gone from a solid middle-of-the-order hitter behind star teammate Jose Ramirez to a star-caliber bat himself, however. He’s out to a blistering .295/.366/.557 start, and it’s not the type of early-season fluke that’s propped up by a .400-something average on balls in play. Naylor’s .274 BABIP is actually 21 points lower than the .295 mark he…
