Josh Naylor, Mariners Finalizing Five-Year Contract

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.

Mariners Pick Up 2026 Option on Andres Munoz

The Seattle Mariners exercised right-handed closer Andres Munoz's $6 million option for the 2026 season on Tuesday, a source told Francys Romero. It was an expected move for the Mariners to keep one of the most dominant relievers in baseball around for another year. The 26-year-old Mexican reliever was an All-Star for a second straight year in 2025, finishing the regular season with a tidy 1.73 ERA (2.43 FIP), 1.03 WHIP, a career-best 38 saves, 83 strikeouts, and 28 walks in 62 1/3 innings out of the bullpen for Seattle. The Mariners could keep the 26-year-old around through the 2028 season, too, as they have an $8 million option on him for 2027 and a $10 million option for 2028. Munoz's walk percentage has been in double digits each of the last three years, but he's made up for it by striking out 32.6% of the batters he's faced in the last three seasons.

Bryce Miller Not Expected to Need Elbow Surgery

Seattle Mariners right-hander Bryce Miller (elbow) said he doesn't expect to need surgery for a right-elbow injury that kept him out for half of the 2025 season. The same can be said for right-handed starters George Kirby (shoulder) and Logan Gilbert (elbow), who also missed around two months each in the first half of the season. Miller added that he has a follow-up exam with Dr. Keith Meister early this offseason to determine his next steps for a small bone spur in his right elbow. The 27-year-old had a platelet-rich plasma injection in his elbow in early June and didn't return to the rotation until Aug. 19, making eight starts over the final eight weeks of the regular season. Miller may receive a cortisone injection early in the offseason, and then maybe another one at the start of spring training. But barring a setback, Miller should be ready for the start of 2026. Fantasy managers shouldn't forget that he ranked among the American League leaders in 2024 with a 2.94 ERA and 180 1/3 innings over 31 starts.

Colt Emerson Competing for an Opening Day Roster Spot in Seattle?

Adam Jude of the Seattle Times reports that "there is expected to be runway" for top Mariners infield prospect Colt Emerson to "win an opening-day job going into 2026." In 2025, Emerson played 90 games with High-A Everett, 34 games with Double-A Arkansas, and six games with Triple-A Tacoma. He slashed .285/.383/.458 with 16 home runs, 78 RBI, 82 runs scored, and 14 stolen bases in 600 plate appearances spread across the three levels. Emerson will not turn 21 years old until July 2026. He's a natural shortstop, but Jude speculates that Emerson's best path to a starting job in Seattle may be at third base. Eugenio Suarez served as Seattle's third baseman down the stretch of 2025, but he is now a free agent. Despite his limited experience at the highest levels of the Minors, it appears Emerson could crack the Mariners 2026 opening day roster if he performs in Spring Training.

Josh Naylor Moves into Three-Hole

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.

Dominic Canzone on the Bench for Game 7

Seattle Mariners outfielder Dominic Canzone is absent from the starting lineup ahead of Monday's ALCS Game 7 against the Toronto Blue Jays. Canzone has been in the lineup almost exclusively against right-handed pitching this postseason. However, he has struggled with only three hits during those nine games. That being said, Victor Robles will take over in right field and bat ninth against right-hander Shane Bieber on Monday. Robles has actually been worse as he's 1-for-12 during this series, so it's possible we see both players during this elimination contest.

Trent Thornton Out of Walking Boot; Aims for Early 2026 Return

Seattle Mariners right-hander Trent Thornton (Achilles) is out of his protective walking boot as he continues to recover from a torn left Achilles tendon. The 32-year-old underwent surgery on August 5 after being placed on the injured list four days earlier. The recovery timeline is expected to be around six to eight months, putting Thornton on track for a possible return by 2026 spring training. He has remained in good spirits while supporting his team during their postseason run. Thornton finished the regular season with a 4.68 ERA and a 1.30 WHIP across 42 1/3 innings.

Logan Gilbert Named Game 6 Starter for ALCS

Seattle Mariners starting pitcher Logan Gilbert has been named the starting pitcher ahead of Game 6 of the ALCS against the Toronto Blue Jays. As expected, Gilbert will get the ball as he attempts to get his team to the World Series for the first time in franchise history. Gilbert gave up three runs (two earned) across three innings of work during Monday's Game 2. The right-hander holds a 2.45 ERA, 1.27 WHIP with 11 strikeouts in 11 innings this postseason. He only threw 58 pitches during his last outing, so he should be fairly fresh for this contest.

Bryce Miller to Start Game 5 of ALCS Against Blue Jays

Seattle Mariners right-hander Bryce Miller will make the start in Game 5 of the American League Championship Series on Friday in Seattle against the Toronto Blue Jays, according to manager Dan Wilson. Right-hander Bryan Woo will be available out of the bullpen if Miller needs help early on. The Mariners will be hoping for a repeat of Miller's Game 1 performance, when he allowed only one run in six innings on short rest for a win. This time, the 27-year-old will be on regular rest while going up against Blue Jays right-hander Kevin Gausman. Miller dealt with injuries in the regular season and made only 18 starts, but he's been better in two postseason starts. In a no-decision in Game 4 of the AL Division Series against the Tigers, he gave up two earned runs with no walks and two K's in 4 1/3 frames. Miller faced Toronto just once in the regular season on May 11 and was hit hard, surrendering seven earned runs on eight hits (one homer) while walking two and fanning three in five innings.

Bryan Woo Tentatively Scheduled for Game 5 of ALCS

Seattle Mariners right-hander Bryan Woo (pectoral) is tentatively scheduled to start Game 5 of the American League Championship Series (if necessary) on Friday against the Toronto Blue Jays, according to Adam Jude of The Seattle Times. Right-hander Logan Gilbert is starting Game 2 on Monday. Right-hander George Kirby will go in Game 3, and right-hander Luis Castillo will start in Game 4. Right-pectoral inflammation kept Woo off the team's roster for the AL Division Series against the Detroit Tigers, but he was included on the ALCS roster and had a successful batting practice session on Monday, clearing him to start later in the series. Woo has been excellent for the Mariners in 2025 when healthy, but his last big-league start came back on Sept. 19 against the Houston Astros, so he will almost certainly be on a pitch-count limit on Friday.

Logan Gilbert to Start Game 2 of ALCS Against Blue Jays

Seattle Mariners right-hander Logan Gilbert will make the start in Game 2 of the American League Championship Series on Monday in Toronto against the Blue Jays, according to manager Dan Wilson. Gilbert, who will be making his third appearance of the postseason on Monday, will be looking to give Seattle a 2-0 lead in the best-of-seven series. The 28-year-old right-hander made one start and one relief appearance in the AL Division Series against the Detroit Tigers and allowed just one run while giving up seven hits, walking one, and striking out nine in eight innings of work. In his lone start against Toronto back on April 19, Gilbert allowed two runs on seven hits while walking two and striking out nine in just 4 2/3 innings of work. He last pitched on Friday in Game 5 of the ALDS against Detroit, tossing two scoreless innings out of the bullpen in the marathon 15-inning contest.

Bryan Woo Makes ALCS Roster

Seattle Mariners starting pitcher Bryan Woo (pectoral) has made the ALCS roster against the Toronto Blue Jays in the upcoming best-of-seven series that starts in Toronto on Sunday night. Woo is back after missing the ALDS due to a pectoral issue. His return is a huge lift for this pitching staff in this seven-game series. Woo posted a 2.94 ERA, 0.93 WHIP, and a 198/36 K/BB ratio across 30 starts in the regular season. It's unclear when he'll take the ball for Seattle or in what role, but having Woo on this roster is a significant boost for a Mariners team that already has a pretty solid pitching staff all the way around.

Bryce Miller Named Game 1 Starter for ALCS

Seattle Mariners starting pitcher Bryce Miller has been named the Game 1 starter for the ALCS against the Toronto Blue Jays. The team has made it official that Miller will take the ball for the first game of the series on Sunday. Miller tossed 4.1 innings on Wednesday, so he'll be pitching on short rest. The right-hander did only throw 44 pitches during his latest outing, but figures to still have an abbreviated start. It's unclear who will follow Miller, but he'll at least get the first chance at it during Sunday's contest.

Bryan Woo Expected to be on Mariners' ALCS Roster

Seattle Mariners President of Baseball Operations Jerry Dipoto said that starting pitcher Bryan Woo (pectoral) is expected to be part of the team's roster for the American League Championship Series, according to Adam Jude of The Seattle Times. Woo has not pitched since September 19 due to pectoral tightness. The 25-year-old was arguably Seattle's best pitcher during the regular season, posting a 15-7 record with a 2.94 ERA, 0.93 WHIP, and 198 strikeouts in 186 2/3 innings (30 starts). Dipoto said that Woo will not pitch until "midway through the series," so it remains unclear who will take the ball for Seattle in Game 1 against the Toronto Blue Jays on Sunday. Seattle used three of its regular starters in George Kirby, Logan Gilbert, and Luis Castillo to close out the ALDS on Friday night.

Bryan Woo Throws Bullpen Session

Seattle Mariners right-hander Bryan Woo (pectoral) threw an up-down bullpen session of around 30 pitches on Friday, Adam Jude of the Seattle Times reports. The AL West-winning Mariners have gone without Woo since he left what turned out to be his final regular-season start on Sept. 19 with pectoral tightness. If the Mariners defeat the Detroit Tigers in a do-or-die Game 5 of the ALDS on Friday, they'll have to determine whether to carry Woo on their ALCS roster against the Toronto Blue Jays. Manager Dan Wilson said the Mariners are "certainly hopeful" that Woo will return if they advance. The 25-year-old was among the key contributors during the Mariners' first division-winning campaign since 2001. Across 30 starts and 186 2/3 innings, Woo went 15-7 with a 2.94 ERA, a .93 WHIP, and 198:36 K:BB.

George Kirby • SP • Mariners

George Kirby Starting Deciding Game 5 of ALDS on Friday

Seattle Mariners right-hander George Kirby will start the fifth and deciding game in the American League Division Series against the Detroit Tigers at T-Mobile Park on Friday, according to Shannon Drayer. Kirby will be opposed by Cy Young candidate Tarik Skubal for Detroit. The 27-year-old Kirby is looking for a second straight strong performance to close out the series after he held the Tigers to two earned runs while striking out eight over five innings in Game 1 of the series. Kirby also faced Detroit back on July 12 and didn't fare as well, allowing four earned runs on five hits (one homer) while walking three and striking out six in five innings in a game that he ended up winning. Kirby will have to be on his game against the dominant Skubal, but he definitely has the skills to do so. If Kirby isn't on his game, right-hander Luis Castillo is probably available early in the game to help pick up the slack.

Josh Naylor Starting for Mariners in Game 3 of ALDS

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.

Logan Gilbert to Start Game 3 of ALDS Against Tigers

Seattle Mariners starting pitcher Logan Gilbert will take the mound for Tuesday's Game 3 of the ALDS versus the Detroit Tigers. The Mariners dropped the opener and will play Game 2 of the series Sunday night. Another loss for Seattle would make Tuesday a win or go home contest. Gilbert finished the regular season on a strong note. The right-hander allowed two earned runs or less in all of his starts in September. Gilbert posted a 3.44 ERA, 1.03 WHIP, and a 173/31 K/BB ratio across 25 starts. He should offer viable DFS value for Tuesday's slate.

Luis Castillo to Start Game 2

Seattle Mariners starting pitcher Luis Castillo will draw the start for Sunday's Game 2 of the ALDS against the Detroit Tigers. The Mariners are in need of a big win here after dropping the opener. It won't be easy versus left-hander Tarik Skubal, but Castillo has looked solid lately. Castillo posted a 2.45 ERA in the month of September. The right-hander gave up three earned runs over his last four starts during the regular season. This is looking like a potential pitcher's duel between two aces on Sunday.

Victor Robles Playing in Game 1

Seattle Mariners outfielder Victor Robles (shoulder) is in the starting lineup ahead of Saturday's Game 1 of the ALDS versus the Detroit Tigers. Robles missed the final three games of the regular season due to a shoulder injury. However, the Mariners had a first-round bye, so that appears to have been enough time for Robles to get healthy. He'll cover right field and bat eighth versus right-hander Troy Melton on Saturday. He's not offering a ton of upside against right-handed pitching right now.
