The move clears a spot for the newly-acquired Jhonny Pereda on the 40-man roster. Kowar, 28, posted a 4.24 ERA and 15/7 K/BB ratio over 17 innings out of Seattle’s bullpen last season. It was his first year back from Tommy John surgery.

Díaz has made a couple of appearances for Seattle over the past couple seasons without much success. The left-hander is now off the 40-man roster and on the waiver wire to make room for the recently-acquired Cooper Criswell.

Criswell was designated for assignment by the Mets on Wednesday. The 29-year-old is capable of working multiple innings, and he’ll compete for one of the final bullpen spots for Seattle this spring.

The Mariners made a mistake last winter in failing to secure starting pitching depth behind their vaunted rotation, but it didn’t wind up hurting them much, as Emerson Hancock and Logan Evans were able to hold their own in their 31 starts. Dunning will add to their alternatives this year after a bumpy 2025 in which he was let go by the Rangers and was limited to 12 relief appearances in the majors. The 31-year-old has a career 4.44 ERA in 102 starts and 34 relief appearances, most of those coming with Texas.

The 28-year-old infielder spent the first seven years of his minor league career in the Nationals’ organization. In 2025, he slashed .252/.329/.390 with seven long balls, 22 RBI, 15 swipes and a 54/22 K/BB ratio over 235 plate appearances between Double-A Harrisburg and Triple-A Rochester. He’ll add infield depth in the upper minors for the M’s.

Miller had been the only Mariners player not to agree before arbitration figures were exchanged. Miller, a Super Two player, filed at $2.625 million, with the Mariners coming in at $2.25 million. The option, which includes a $15,000 buyout, is for $6 million but is also voided if Miller finishes in the top five of the AL Cy Young voting, which is the kind of thing that would have to happen for Miller to approach $6 million in arbitration next year. It has no real chance of being applied and is only here because it keeps up appearances of the Mariners being a so-called “file and trial” team.

Miller had been the only Mariners player not to agree before arbitration figures were exchanged. Miller, a Super Two player, filed at $2.625 million, with the Mariners coming in at $2.25 million. The new deal will obviously be somewhere in the middle there, with the 2027 option to be priced at an amount that exceeds most expectations for Miller’s 2028 arbitration salary.

Zulueta heads to Seattle just a few hours after being jettisoned from Cincinnati’s 40-man roster. The 27-year-old former relief prospect fits the mold for the Mariners bullpen as a sinker/slider combo power arm that holds a serviceable 4.21 FIP and 25/11 K/BB ratio across 23 2/3 innings at the big-league level since 2024.

Taylor loses his spot on Seattle’s 40-man roster after the club acquired reliever Yosver Zulueta from the Reds in a small trade. The 27-year-old offers some defensive versatility, but he hasn’t produced in limited opportunities at the major-league level over the past three seasons. He’s gotten into 38 games between the Royals and Mariners during that span, batting .205 (15-for-73) with zero homers and eight steals. He should attract some interest on waivers as a jack-of-all-trades utility specialist.

Rucker hasn’t resurfaced in the majors since making 96 relief appearances for the Cubs from 2021-2023, posting a respectable 4.57 FIP and 120/50 K/BB ratio across 123 1/3 innings during that span. The 31-year-old journeyman righty didn’t pitch anywhere last year after spending the previous season in the Phillies system. He’s merely emergency organizational depth at this juncture of his career.

The Pirates made Siani the 37th overall pick in the 2019 MLB Draft but he never reached Pittsburgh, topping out at Triple-A Indianapolis this past season where he batted .261/.337/.424 with four homers and three steals in 104 plate appearances over 25 games. The change of scenery is the wild card variable, but it seems unlikely he’ll morph into an impact fantasy contributor at this stage of his development. The 25-year-old is likely ticketed for Triple-A Tacoma after spring training.

Gilbert was a Super Two player after 2023, so this is his third of four years in arbitration. The 28-year-old had a 3.44 ERA and a 173/31 K/BB in 131 innings last season, though he did serve his first ever IL stint with an elbow strain in the first half of the year. Despite that, he still tracks as a top-five fantasy SP in 2026.

Kirby missed time with a shoulder injury in 2025 and pitched to a 4.21 ERA, 1.19 WHIP, and 137/29 K/BB ratio in 126 innings. Kirby had pitched at least 190 innings in each of the two previous seasons with an ERA in the mid-3s. He has not really developed as a strikeout arm, but he is a good bet to produce good ratios on a winning team, which makes him a solid option in fantasy baseball leagues.

Arozarena’s deal was the most expensive of the early stages of the arbitration agreements. The 30-year-old was an All-Star in 2025, hitting .238/.334/.426 with 27 home runs and 31 steals in his second season in Seattle. He also set a career-high with 191 strikeouts in 160 games played. His batting average will likely never be strong, but he contributes enough in the other categories to be a solid fantasy asset.

Wisdom has slashed .209/.291/.459 in seven MLB seasons with 88 home runs in 455 games. He spent last year in Korea, hitting .236/.321/.535 with 35 home runs and 85 RBI in 119 games. His power is unquestioned, but his questionable contact makes it hard for him to stick on an MLB roster.

It’s worth $1 million, according to MLB.com’s Daniel Kramer. Knizner secures a big-league deal after hitting .221/.299/.299 in 33 games for the Giants last season. Somewhat interesting is that he had the best defensive numbers of his career during that span. He also struck out at half of his career rate (10/7 K/BB in 88 plate appearances). He’s the clear backup to Cal Raleigh at the moment, though the Mariners still might have interest in a Mitch Garver reunion if the price proves right.

The 25-year-old hurler finished the 2025 season as the Nationals’ closer. He compiled a 4.48 ERA, 1.27 WHIP and a 71/16 K/BB ratio across 76 1/3 innings while securing 11 saves for the Nationals. He’ll add another talented weapon to the M’s bullpen, but he won’t be anywhere near the top of the pecking order in saves, which saps most of his fantasy value.

The textbook example of emergency pitching depth, Lawrence oscillated between Seattle’s bullpen and Triple-A Tacoma numerous times this past season, pitching to a respectable 3.00 ERA while gobbling up 15 innings over five long relief appearances. He also made one relief appearance for the Blue Jays in late April before returning to the Mariners. The 38-year-old journeyman is back as Seattle’s ultimate contingency plan — the arm you don’t expect to need, but are grateful to have when things go completely sideways.

Zuñiga returns as organizational relief depth for Seattle after latching on in early September after being cut loose by the Phillies. The 27-year-old, who didn’t appear in the majors last year, holds a pedestrian 5.03 ERA over 19 2/3 innings over 17 appearances in the big leagues since 2023.

Saucedo loses his spot on Seattle’s 40-man roster after the club picked up reliever Alex Hoppe in a trade with the Red Sox. The 32-year-old southpaw struggled to a calamitous 7.43 ERA over 13 1/3 inning across 10 appearances this past season in the majors.

Hoppe provides Seattle with some additional relief depth entering next season after posting a respectable 4.55 ERA, 1.52 WHIP and 73/34 K/BB ratio across 61 1/3 innings over 44 appearances between Double-A Portland and Triple-A Worcester. The 26-year-old righty was a sixth-round pick in the 2022 MLB Draft.

The deal is now official. Naylor returns to Seattle after a phenomenal postseason in which he hit .340 (16-for-47) with three homers and two steals across 12 games. The 28-year-old slugging first baseman is coming off the best all-around season of his career, slashing .295/.353/.462 with 20 homers, 92 RBI and a surprising 30 steals over 147 games between the Mariners and Diamondbacks. He’s an extremely challenging hitter to project given his volatile year-to-year power output and an out-of-nowhere spike in stolen bases after recording just 22 swipes combined over the previous three seasons. It’s worth noting that T-Mobile Park remains one of the toughest environments in baseball for left-handed power — though hitters like Naylor tend to treat park factors as optional suggestions rather than actual limitations. Even so, Naylor has firmly established himself as a top-10 fantasy first baseman heading into next season.

The move comes just 10 days after the Dodgers added Ortiz to the 40-man roster to prevent him from becoming a minor league free agent. Ortiz, who turns 26 in January, had a 2.73 ERA and a 72/33 K/BB in 59 1/3 innings split pretty evenly between high-A, Double-A and Triple-A last season. His mid-90s sinker and mid-80s slider might make him a decent MLB reliever, but he’ll probably open next season in Triple-A.

The Mariners lacked rotation depth beyond their big five last season, and addressing that should be an in the plans for this winter. Dobnak, who debuted with the Twins in 2019 but has barely pitched in the majors the last four years, doesn’t really qualify as a quality fallback at this point — he had a 5.84 ERA in Triple-A last season — but maybe Seattle sees something for him to work on.

Since debuting with the Cardinals in 2024, Loutos has given up 17 earned runs and struck out eight in 12 innings as a major leaguer. He’ll probably wind up back on waivers later this winter, but if not, he’ll battle for a bullpen spot in spring training.

Wilcox was the last of the four players from the Blake Snell trade with the Padres still with the Rays. He made just one major league appearance for the team, giving up seven runs — three earned — in one inning in September. In Triple-A, he showed improved velocity, averaging 95.8 mph with his fastball, and had a 3.70 ERA and a 63/27 K/BB in 58 1/3 innings. He’ll be a long shot to claim a bullpen spot out of spring training.

Just turning 27 in January, Muñoz would have co-headlined this year’s reliever class with Edwin Díaz had he not signed a long-term deal as a 22-year-old. He’ll get about one-third of his fair-market value next year, and the Mariners will still have club options on him for $8 million in 2027 and $10 million in 2028. At least he can earn up to an extra $2 million next year based on games finished.

Garver had a $12 million mutual option for 2026, but he will instead be paid $1 million and become a free agent. It was a rough stretch for Garver as a Mariner, hitting .187/.290/.341 in 720 plate appearances with 24 home runs and a nearly 30 percent strikeout rate over two seasons. He might find a bidder as a potential designated hitter.
