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 carried into the season, in fact. So what’s changed?

For starters, the K-BB profile has only continued to get better. He’s walking at an 8.9% clip that’d be right in line with his 9% career-best mark from back in his rookie season. His 10.9% strikeout rate isn’t just a career-best — it’s tied with Mookie Betts for the eighth-lowest in MLB. Naylor has always been a free swinger who’s chased off the plate a lot; he swung at 38.4% of pitches off the plate in his career prior to 2024. This year, he’s at 32.6%. His overall contact rate is actually down a tick, but that’s easier to stomach when he’s laying off more bad balls and working himself into better counts.

It’s also in part due to what appears to be a conscious effort to do more damage at the plate. More than half of Naylor’s batted balls (50.4%) were hit on the ground through his first four seasons. He lowered his ground-ball rate in each of his first four MLB seasons but took a major jump in 2023, cutting that grounder rate from 48.9% in ’22 to 42.7%. This year, Naylor is only putting 40.5% of his batted balls on the ground. Both his 22.8% line-drive rate and 36.7% fly-ball rate are career-high marks.

As one would expect, elevating the ball more regularly is leading to considerably more damage. Naylor may be sacrificing a bit of contact, but he possesses such strong bat-to-ball skills that you’ll rarely see him swing through multiple pitches in the same at-bat. And the extra oomph in his swing is producing better results not just in his rate stats but in the under-the-hood numbers as well. Naylor’s 90.7 mph average exit velocity, 12.7% barrel rate and 44.3% hard-hit rate — as measured by Statcast — are all easy career-highs. He’s seen 20.7% of his fly-balls clear the fence for home runs — a major improvement over his career 13% mark and the single-season career-high of 15.9% he established in 2022.

For years, the Guardians have forged an identity as a team full of pesky, tough-to-strike-out hitters who put the ball in play but also generally lacked pop. Ramirez was a true heart-of-the-order slugger who managed to embody that contact-driven focus while still hitting for power, but Cleveland lacked anyone else who fit that profile. It’s early in 2024, but Naylor looks to be figuring out the recipe for toeing that same line. The six homers he’s hit in 101 plate appearances is already one shy of his 2021 total in 250 plate appearances and already 30% of the way to his career-high in only 20% the playing time.

Still just 26 years old, Naylor remains in his physical prime and is refining an already strong approach and plan at the plate in a way that’s letting him tap into the 60- to 70-grade marks that scouts put on his power during his prospect days. In doing so, he appears on the cusp of breaking out as a potentially elite hitter.

Heading into the season, with questions about how the Guardians would fare coming off a disappointing 2023 season, it was reasonable to view Naylor as a possible summer trade candidate. Multiple clubs expressed interest him over the winter. He’s expensive by Cleveland standards, earning $6.55MM this year, and will very likely command a raise to north of $10MM in 2025 — his final season of club control. The Guardians have a habit of trading players before the get to the point where they could test free agency.

But Cleveland’s excellent start to the season, even in the midst of a severe slate of pitching injuries, should have fans of other clubs pumping the brakes on the idea of prying Naylor from the Guardians’ grasp. If the wave of pitching injuries proves to be too difficult to withstand and the Guards eventually fall out of the race, it could still be a possibility. But right now, Naylor is one of the driving factors in Cleveland’s hot start to the season and breaking out as a critical cog in a lineup that’s vastly exceeding expectations.
