Josh Naylor Fantasy Stats

Seattle Mariners first baseman Josh Naylor was one of the first dominoes to fall in free agency this past winter, re-signing with Seattle on a five-year contract in mid-November. Naylor posted an excellent season in 2025 across 604 plate appearances split between the Mariners and Arizona Diamondbacks, slashing .295/.353/.462 with 20 home runs, 92 RBI, 81 runs scored, and 30 stolen bases. The 28-year-old's speed breakout was the most surprising aspect of his profile, as he had logged just 22 combined steals across the three seasons before 2025. 19 of Naylor's stolen bases came in the 54 games he played for Seattle, so the Mariners could be encouraging him to run even more in 2026. With just a 6.6% barrel rate in 2025, Naylor's underlying power metrics suggest that he may not provide surplus fantasy value in the home run category. However, he struck out at just a 13.7% rate last season, and should have an opportunity to collect counting stats given his everyday role in the top-heavy Mariners lineup. RotoBaller currently ranks Naylor as the number eight first baseman in traditional rotisserie scoring fantasy formats.

First baseman Josh Naylor and the Seattle Mariners are finalizing a five-year contract on Sunday evening, sources familiar with the deal told ESPN's Jeff Passan. The Mariners will now keep Naylor around for the foreseeable future after acquiring him at this year's trade deadline from the Arizona Diamondbacks. The 28-year-old Canadian left-handed slugger hit .299 (58-for-194) with nine home runs, 33 RBI, 32 runs scored, and 19 stolen bases in 54 regular-season games after being traded to Seattle. Overall, he slashed a strong .295/.353/.462 with an .816 OPS, 20 home runs, 92 RBI, 81 runs scored, and a career-high 30 stolen bases in 147 games in his seventh year in the majors. Naylor ranked in the 66th percentile in xwOBA, 42nd percentile in xBA, and 43rd percentile in hard-hit rate, suggesting his 31-homer campaign in 2024 is a ceiling that could be hard to reach again. Fantasy managers also shouldn't expect a repeat in the steals department, with his previous high-water mark in that category being 10.

Seattle Mariners first baseman Josh Naylor will move into the three-hole in the lineup ahead of Monday's Game 7 of the ALCS against the Toronto Blue Jays. Naylor has mainly been batting cleanup or fifth during this series. However, he'll move into the third spot with Jorge Polanco sliding into the cleanup spot during this elimination contest. Naylor has been on fire at the plate with a .341 batting average and three home runs during the postseason. The Mariners want to keep their hot hitting left-handed slugger near the top of the order for this one. We'll see if he's able to do any damage against right-hander Shane Bieber and help send his team to their first ever World Series.

Seattle Mariners first baseman Josh Naylor (personal) is starting at first base and hitting fifth on Tuesday for Game 3 of the American League Division Series at Comerica Park against right-hander Jack Flaherty. It was unclear if Naylor would be available for Game 3 of the ALDS after he did not travel with the team to Detroit to stay behind while he and his wife were expecting the birth of their first child. The 28-year-old has rejoined the team and will start on Tuesday, though, after going hitless in eight at-bats with a walk and a strikeout in the first two games of the series. Naylor will be looking to get back on track offensively in Game 3, and he has three hits in 12 plate appearances with two walks and a strikeout in his career against Flaherty.

Seattle Mariners first baseman Josh Naylor (personal) is in the starting lineup for Saturday's Game 1 of the ALDS against the Detroit Tigers. Naylor missed the final two games of the regular season due to groin soreness. However, that's not the reason why Naylor could miss time during this series. Naylor could end up on the paternity list, with his wife expected to go into labor soon. He's in the lineup on Saturday, but that doesn't mean that Naylor won't miss time during this series. He'll bat cleanup and cover first base versus Troy Melton on Saturday.

Seattle Mariners first baseman Josh Naylor (groin) left his team's game on Friday against the Los Angeles Dodgers due to "minor groin tightness," according to Ryan Divish of The Seattle Times. The Mariners have the American League West and a spot in the American League Division Series locked up, so it wouldn't be a surprise to see Naylor get the final two games of the regular season off. The 28-year-old has been excellent across 604 plate appearances this season, slashing .295/.353/.462 with 20 home runs, 92 RBI, 81 runs scored, and 30 stolen bases. First baseman/outfielder Luke Raley could be the most likely candidate to step in for Naylor in Seattle if he misses time.

Seattle Mariners first baseman Josh Naylor (undisclosed) left early against the Los Angeles Dodgers on Friday with an apparent injury. After Naylor stole his 30th base of the season in the third inning, he began "exhibiting some discomfort," according to Daniel Kramer of MLB.com. The Mariners later pinch-hit Mitch Garver for Naylor in the fifth inning. Naylor went 1-for-2 before departing and became just the third first baseman to reach 20 home runs and 30 steals in a season, joining Jeff Bagwell and Paul Goldschmidt. With the Mariners having already clinched the AL West, the hope is that they pulled Naylor as a precautionary measure. The 28-year-old has been an outstanding addition for Seattle since it acquired him from the Arizona Diamondbacks in late July. Along with his 20 HRs and 30 steals, Naylor has slashed .295/.353/.462 with 92 RBI and 81 runs scored in 147 games and 604 plate appearances this year.

Seattle Mariners first baseman Josh Naylor (illness) is feeling better and is starting at first base and batting cleanup for Saturday's tilt against the hosting New York Mets and rookie right-hander Nolan McLean, who will be making his major-leagu debut. Naylor was under the weather and did not play in Friday's series opener at Citi Field, but the 28-year-old left-handed slugger is back in there now and hitting in the heart of Seattle's batting order. The Canadian first baseman should be returned to starting fantasy lineups against the rookie right-hander on Saturday. It's been a strong season for Naylor, although he does have only 15 home runs in 414 at-bats. Since the Mariners acquired him from the Arizona Diamondbacks, he's gone 19-for-65 (.292) with four home runs, 10 RBI, 11 stolen bases and 11 runs scored in 18 games.

Seattle Mariners first baseman Josh Naylor (illness) is under the weather and will not play in Friday's series opener at Citi Field against the New York Mets. With Naylor out, Donovan Solano will start at first base and bat seventh against Mets left-hander Sean Manaea. Catcher Mitch Garver is the designatd hitter and is batting sixth. There's a good chance that Naylor will be back in the lineup for Game 2 of the series on Saturday, so fantasy managers will want to check back then. The 28-year-old Naylor has continued to hit well after being traded from the Arizona Diamondbacks last month, as he's gone 19-for-65 (.292) with four home runs, 10 RBI, 11 runs scored and 11 stolen bases in his first 18 games with the M's. Solano could be a worthwhile DFS sleeper on Friday with a career .300 average in 10 at-bats versus Manaea.

Seattle Mariners first baseman Josh Naylor (shoulder) is out of the team's starting lineup for Friday's series opener against the visiting Tampa Bay Rays at T-Mobile Park. Donovan Solano will man first base and hit seventh for the M's against Rays right-hander Drew Rasmussen. Naylor was pulled from Thursday's win over the Chicago White Sox early due to soreness in his left shoulder and he'll miss the first game of the series against Tampa as a result. Fantasy managers should consider the 28-year-old lefty slugger day-to-day for the time being. Since being acquired in a trade from the Arizona Diamondbacks, Naylor has gone 12-for-46 (.261) with three home runs, a double, six RBI, 10 stolen bases and eight runs in only 13 games. Naylor was a first-time All-Star in 2024 and is already at a career high for steals in 2025 with 21.
