Naylor and the Mariners are finalizing a five-year contract Sunday, pending a physical, Jeff Passan of ESPN.com reports.

EDGE 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.

Naylor went 2-for-4 with a solo home run in Sunday's 6-2 loss to the Blue Jays in Game 6 of the ALCS.

EDGE Analysis

Naylor notched a single in the top of the fourth inning and later launched a two-out solo home run off Trey Yesavage in the top of the sixth. The first baseman is now batting .341 with three home runs, four RBI, seven runs scored and two stolen bases over 44 at-bats in 11 games so far in the postseason.

Naylor (personal) will start at first base and bat fifth Tuesday in Game 3 of the ALDS versus the Tigers.

EDGE Analysis

Naylor's availability for Game 3 had been in question, as he did not travel with the Mariners to Detroit while he and his wife were expecting the birth of their first child. He has since rejoined the team and is in the lineup as the series moves to Detroit. Naylor is 0-for-8 with a 1:1 BB:K in the first two games of the ALDS.

Mariners manager Dan Wilson said Monday that Naylor is with his expecting wife and it's uncertain whether the first baseman will be available for ALDS Games 3 and 4 in Detroit, Daniel Kramer of MLB.com reports.

EDGE Analysis

Naylor did not travel with the team as he and his wife await the birth of their first child. He could be placed on the paternity list, which would make him unavailable for 1-to-3 games, but it does not seem to be a given that that move will be made. Luke Raley or Eugenio Suarez could fill in at first base if Naylor has to miss time. If it's Suarez who is used at first base, the Mariners would install Ben Williamson at third base. Naylor has gone 0-for-8 with a 1:1 BB:K in the first two games of the ALDS versus the Tigers.

Naylor (groin) will start at first base and bat fourth in Saturday's ALDS Game 1 matchup against the Tigers.

EDGE Analysis

Groin soreness kept Naylor out of the lineup for the Mariners' final two regular-season games, but he's now feeling well enough to rejoin the starting nine for the beginning of the ALDS. The 28-year-old may still have to miss time during the series, however, as his wife is expected to go into labor in the very near future.

Naylor (groin) is not in the starting lineup for Sunday's game against the Dodgers.

EDGE Analysis

The Mariners won't risk Naylor ahead of the playoffs after he was pulled from Friday's game with groin tightness. Luke Raley will start at first base and bat sixth against left-hander Clayton Kershaw in Seattle's final regular-season game of 2025.

Naylor (groin) isn't in the lineup for Saturday's game against the Dodgers.

EDGE Analysis

Naylor's groin tightened up on him while he collected his 30th steal of the season Friday, and he'll remain out for at least one more game Saturday. His absence will open up first base for Luke Raley, who will bat seventh against right-hander Tyler Glasnow.

Naylor was pulled from Friday's game against the Dodgers with minor groin tightness, Ryan Divish of The Seattle Times reports.

EDGE Analysis

Naylor seemingly suffered the injury while stealing second base in the third inning Friday, leading to his eventual removal in the fifth. The fact that his groin issue is being described as minor is a good sign that he'll be healthy for Seattle's postseason run, although the M's may still err on the side of caution and hold him out for the final few games of the regular season.

Naylor was removed from Friday's game against the Dodgers with an apparent injury, Daniel Kramer of MLB.com reports.

EDGE Analysis

Naylor was visibly uncomfortable after swiping second base in the third inning of Friday's contest, and he was eventually lifted for a pinch hitter in the fifth. The Mariners will take a closer look at him to determine what the issue is and should relay their findings in the near future.

Naylor went 2-for-4 with a double and three RBI in Tuesday's win over the Rockies.

EDGE Analysis

Naylor came through in the clutch, ripping a bases-clearing double with two outs in the eighth inning to put the Mariners ahead and help secure a postseason berth. Since arriving from the Diamondbacks at the trade deadline, he's maintained his production, posting an .819 OPS in Seattle after logging an .807 mark in Arizona. For the season, the first baseman owns a .292/.351/.461 slash line with 28 doubles, 20 homers, 91 RBI and 28 stolen bases across 144 games.
