Sticking with Seattle
Naylor and the Mariners are finalizing a five-year contract Sunday, pending a physical, Jeff Passan of ESPN.com reports.
Analysis
Naylor will remain with Seattle after being traded to the team from Arizona in late July. The first baseman compiled a .295/.353/.462 slash line while producing 20 home runs, 92 RBI, 81 runs scored and a career-high 30 stolen bases over 147 regular-season contests with the Diamondbacks and Mariners in 2025. Naylor registered a .299 average with nine homers and 33 RBI in 54 regular-season games with Seattle. The 28-year-old will now hold down the first-base position for the team for a half-decade moving forward.

Stat Review
How does Josh Naylor compare to other hitters?
This section compares his stats with all batting seasons from the previous three seasons (minimum 400 plate appearances)*. The bar represents the player's percentile rank. For example, if the bar is halfway across, then the player falls into the 50th percentile for that stat and it would be considered average.
* Exit Velocity and Barrels/PA % are benchmarked against 2019 data (min 400 PA) and Hard Hit Rate is benchmarked against last season's data (min 400 PA). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.

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.

Latest Fantasy Rumors
Pirates were interested
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.
