2026 Fantasy Outlook
Naylor showed last season that stolen bases are more about instincts and reading the opposing pitcher than anything else, swiping 30 bags in 32 attempts despite ranking near the very bottom of the sprint speed leaderboard. It was a surprising surge in the SB category to say the least for a first baseman that had never previously exceeded 10 steals in a season. Stolen bases aside, Naylor also smacked 20 homers in 147 regular-season games between Arizona and Seattle, hitting above .290 at both stops. The lefty slugger added three homers and a .967 OPS in the playoffs, recording four three-hit games between the ALDS and ALCS. Naylor quickly re-upped with the Mariners, inking a five-year deal to remain in Seattle. The home park is a big negative on paper, but Naylor is clearly comfortable there, and they let him run to his heart's content. At 28 years old, he has surpassed 90 RBI each of the last three years and remains in a great position to produce runs hitting behind the likes of Julio Rodriguez and Cal Raleigh. Read Past Outlooks

Swipes two bags Saturday
1BSeattle Mariners
April 25, 2026
Naylor went 2-for-5 with two stolen bases in Saturday's 11-9 win over the Cardinals.
Analysis
He was one of only two Mariners starters who failed to produce either a run or an RBI in the wild victory, but Naylor still found some fantasy value on the basepaths. The first baseman is doing his best to show that his 30-steal campaign in 2025 was no fluke, and through 26 games this season he's gone a perfect 4-for-4 on stolen base attempts. Naylor's also putting a quiet start to the year at the plate behind him, batting .357 (15-for-42) over his last 11 games with three homers, five runs and nine RBI.

Naylor had a wonderful season of volume as he has embraced the role of hitting cleanup for the Guardians behind the likes of Steven Kwan and Jose Ramirez. Naylor rarely took a day off and remained in the lineup against righties and lefties to set career highs in the run production categories. The overexposure to lefties was part of the reason for his batting average tumble, as he hit .224 against lefties in 174 plate appearances, but the 70-point tumble in his batting average against righties hurt Naylor more. Naylor's contact rate remains one of the better ones for a slugging first baseman, and repeating 30-plus homers could be tough for him, given his historical HR/FB rates, but another season of 600-plus plate appearances will make it possible. He has big shoes to fill after being acquired by the Diamondbacks following the departure of Gold Glove first baseman Christian Walker.
Naylor had a career season at the plate despite missing over a month with an oblique injury. The career year was fueled by a few things Naylor had never done, such as hitting .363 with runners in scoring position and hitting .299 against left-handed pitching. He also fully leaned into the roster trend of better contact as Naylor lowered his strikeout rate for a fourth consecutive full season. He also murdered fastballs hitting .352 (.317 xBA.) The amalgamation of those skills is what allowed him to drive in 90+ runs with fewer than 20 homers, something only Naylor, Abreu, Heim, and Bohm did in 2023 and something last done by Asdrubel Cabrera in 2019. In all, Naylor plated 22% of his baserunners, which was only bested by Heim, Mullins, and Seager last season. All of this is to say this big step forward needs to have that first 500+ plate appearance offseason to offset the regression which is likely coming to his run production.
Naylor was limited to 69 games in 2021 after he underwent surgery to address a broken ankle, which briefly delayed his start to 2022. He appeared in 122 games and served as a platoon option at first base and designated hitter, and he had significant struggles against left-handed pitching with a .512 OPS in 127 plate appearances. Naylor clubbed 20 home runs total and crushed righties with a .283/.334/.522 slash line, which should at least keep him on the strong side of a platoon to open 2023. He also had solid strikeout and walk rates (16.1 percent and 7.8 percent, respectively), which provides a solid floor for his 2023 outlook, especially if he's able to improve when facing southpaws.
Naylor's 2021 season was cut short after a broken ankle in late June required season-ending surgery. Naylor is reportedly making good progress in his recovery from July 3 surgery to address fractures and ligament damage in his right leg, but he's not expected to be cleared for Opening Day. Once he completes his rehab program and is able to play a few games in the minor leagues, Naylor should eventually settle into a strong-side platoon role for the Guardians at either corner-outfield spot, first base or designated hitter. Before sustaining the season-ending leg injury, Naylor supplied a .700 OPS in 249 plate appearances for Cleveland in 2021.
Naylor broke summer camp with the Padres, but he played sparingly and almost exclusively against right-handers. He was sent to the alternate site for 10 days in August before returning. Naylor was slashing .278/.316/.417 when he was dealt to Cleveland on Aug. 31. He played more with Cleveland, but still only against righties, slashing just .230/.277/.279. While it's encouraging Naylor's season-long contact rate was 86.4%, it was mostly weak and on the ground, not conducive for a 70 raw power grade. Naylor's average exit velocity on flyballs was well below average, again not good for homers. Naylor is another case in which it's better to trust the reports and results prior to 2020 over a two-month sample in trying conditions. Cleveland's outfield is in flux, though Naylor should be given a shot at the busier side of a platoon.
Naylor made his debut May 24 and was up and down a few times before settling in for good after the deadline. Some scouts have put a 70 on Naylor's raw power, but he's still working to get to that in games. His ISO with the major-league team was .154, so about league average. He walked at a useful clip but his strikeout rate nearly doubled with the jump from Triple-A to the majors, and in total, Naylor graded out as 11% worse than league average by wRC+. As expected, the lumbering Naylor was a negative on defense, and he was below replacement level by fWAR in his 279 plate appearances. The body is a problem -- he was listed at 5-foot-11, 250 pounds at age 21 -- and that figures to only get worse with age. San Diego would like to trade Wil Myers, but that seems unlikely. There will only be room for two starters between Trent Grisham, Myers and Naylor, with Tommy Pham in the same outfield.
The biggest development for Naylor in 2018 was that most of his starts came in left field. He had previously only played first base. His stats through 170 career games at Double-A (.286/.368/.423, 19 HR, 14.0 K%, 10.7 BB%) are solid for a player who won't turn 22 until June. However, the fact he won't be a good defender anywhere, particularly in the outfield, means he will have to do a ton of damage at the plate to get playing time in the National League. The 70-grade raw power that led to him getting selected in the first round in 2015 has not consistently shown up in games, but he has been a better pure hitter than originally anticipated. Eric Hosmer signed an eight-year deal last offseason and the Padres already have a couple bat-first, below-average defenders competing for time in the outfield corners (Franmil Reyes and Hunter Renfroe), so Naylor feels like a spare piece who may not make his big-league debut as a member of this organization.
For each of Naylor's intriguing fantasy-relevant qualities, he does something else that subtracts from his potential value. He has huge raw power, but doesn't make much of an effort to get to it consistently in games. One of pro sports' modern marvels is how well Naylor runs, given his pear-shaped physique. But he won't remain this nimble as he gets into his mid-20s. Prior to 2017, he hardly walked -- a red flag for a bad-body first baseman. However, his career-best 9.1 percent walk rate at Double-A helped lessen those concerns. At the same time, he pulled the ball a career-low 31.4 percent, which was the second lowest rate in the Texas League. For a player who is already not capitalizing on his top physical tool, this new passivity is quite troubling. Naylor could be a high-average 15-to-20 homer hitter, or a low-average 30-plus homer threat, but it's hard to see both skills converging. He has been promoted aggressively since being drafted 12th overall in 2015, and could be pushed to Triple-A before he turns 21 in late June.
Naylor was one of the more desired pieces in the infamous Andrew Cashner-Jarred Cosart deal, which nearly fell through due to alleged misinformation provided by the Padres. The Padres were able to keep Naylor, though, and he more than held his own during his first season of full-season ball. In 122 games between Low-A Greensboro and High-A Lake Elsinore, the left-handed hitting Naylor batted .264/.302/.407 with 12 home runs, 75 RBI and 11 steals. Naylor needs to work on his patience at the dish, as he only drew 25 walks in 481 at-bats. However, he also does not strike a ton, as evidenced by his 84 strikeouts over the above-referenced 122-game span in 2016. The Padres are banking on Naylor's home run totals eventually catching up to his massive raw power. He may only be starting to scratch the surface of his enormous power potential.
After being selected with the 12th pick in the 2015 draft, Naylor injected a modicum of hope into perhaps the worst farm system in baseball. The Canadian slugger slashed .327/.352/.418 with one home run in 25 games in his first taste of professional baseball. Perhaps the most impressive aspect of this small sample is the 10.5-percent K rate that he posted after just turning 18 years old in June. He was drafted because of the plus power he offers from the left side, and to show those contact skills at such an early age has to really excite fantasy owners. While a case could easily be made that Naylor is the best fantasy asset in the Marlins’ system, it is also worth noting that he is at least four or five years away from the show, so drafting him in dynasty leagues will require extreme patience.

Latest Fantasy Rumors
Pirates were interested
1BSeattle Mariners
November 19, 2025
Per Jeff Passan of ESPN, the Pirates had interest in Naylor before he re-signed with the Mariners.
Analysis
The first baseman is back with Seattle on a five-year, $92.5 million contract, which is more than double the largest free-agent contract ever doled out by Pittsburgh. Naylor was traded by the Guardians to the Diamondbacks last winter before being flipped to the Mariners in July, and he enjoyed a productive regular season in 2025 with 20 homers, 30 steals and a .295/.353/.462 slash line in 147 regular-season games. He'll be a key lineup piece for the Mariners going forward and likely won't be going anywhere given that the contract includes a no-trade clause.
