Mariners Sign Drew Pomeranz To A Minor-League Deal

The Seattle Mariners have signed pitcher Drew Pomeranz to a minor-league contract. Pomeranz hasn't pitched in the majors since 2021 when he underwent Tommy John surgery and experienced setbacks in his recovery efforts. The 2024 season was spent in the Dodgers' organization, although the lefty tossed only nine innings for the Triple-A affiliate. The veteran will likely need to prove he's still got something left in the tank before we see him in the majors in 2025, so for now he doesn't move the needle for fantasy. Once upon a time in 2016, the now-36-year-old was an All-Star, so perhaps if he's 100% healthy then there could be something there. For his career, Pomeranz has a 3.91 ERA, 1.35 WHIP, and a 14.0% K-BB% which is a tad low due to his tendency to walk batters at an above-average rate.

Several Teams Inquiring On Luis Castillo

According to Ken Rosenthal of The Athletic, The Chicago Cubs, Boston Red Sox, Baltimore Orioles, and New York Mets are among the teams inquiring about Seattle Mariners starting pitcher Luis Castillo. Rosenthal noted that while the Mariners are not actively searching for a trade partner, they would be eager to do business to improve other aspects of their roster. With their rotation being their strong suit, moving Castillo could bring an impact bat into the Seattle lineup. In addition, Rosenthal noted that if Castillo were to be traded, this could open up some salary for the Mariners to target free agent first baseman Christian Walker, who has been connected to Seattle throughout the offseason. While Castillo's ratios took a slight step down last season, the 32-year-old remains a high-volume starting pitcher who has logged at least 150 innings over the past three seasons and over 175 in the past two.

Yunior Marte Agrees To Minor-League Deal With Seattle

According to Francys Romero, the Seattle Mariners and relief pitcher Yunior Marte have agreed to a minor-league deal. This deal also includes an invite to spring training. Marte spent the past two seasons pitching in Philadelphia after making his debut in San Francisco in 2022. Last summer through 26 innings of work, the right-hander held a 6.92 ERA and 1.88 WHIP with an 18:25 BB:K. In Triple-A, he posted a 6.88 ERA and 2.06 WHIP. Through the summer, Marte generated a rough 6.53 xERA and a hefty 42.7% hard-hit rate. Given his struggles in 2024, Marte will likely face an uphill battle to make the Opening Day Roster, but he could earn a middle-relief role if he has a successful spring training.

Brandyn Garcia Could Make Opening Day Roster

Seattle Mariners left-hander Brandyn Garcia has emerged as a realistic candidate to make the team's Opening Day roster in 2025. Garcia was the team's 11th-round pick out of Texas A&M in 2023 and pitched exclusively out of the bullpen in college. The 24-year-old southpaw won the team's minor-league co-pitch of the year in 2024 and has emerged as one of Seattle's best pitching prospects. He held a 2.25 ERA with 134 strikeouts, 47 walks and only four home runs allowed over 116 innings in 27 appearances (25 starts) with High-A Everett and Double-A Arkansas this past season. Garcia could be a starter in the big leagues in the long term, but the Mariners view him as a potentially valuable left-handed arm out of their bullpen next year. His transition to the bullpen during spring training will be something to watch next spring.

Mariners Optimistic Matt Brash Can Return In Late April

Seattle Mariners right-hander Matt Brash (elbow) had an internal-brace procedure in early May, but he has been working out at the team's spring training facility in Arizona this fall and is ahead of schedule in his rehab from elbow surgery. As a result, the Mariners are optimistic that Brash could return to their bullpen by the end of April. Seattle's bullpen was hampered by injuries all year in 2024, so the return of Brash to a key late-inning role as a setup man would be excellent news for the M's. The 26-year-old Canadian hurler was excellent in his second major-league season in Seattle in 2023, going 9-4 with a 3.06 ERA (2.26 FIP), a 1.33 WHIP, his first four career saves, 107 strikeouts and 29 walks in 70 2/3 innings over a league-high 78 appearance out of the bullpen.

Mariners Acquire Austin Shenton From Rays

The Seattle Mariners acquired infielder Austin Shenton from the Tampa Bay Rays on Tuesday in exchange for cash considerations. In a corresponding move, the Mariners designated right-hander JT Chargois for assignment. Shenton was originally drafted by Seattle in the fifth round in 2019 out of Florida International. The 26-year-old made his major-league debut with the Rays in 2024 but played in only 19 games, going 9-for-42 (.214) with a homer, three RBI and three runs scored. He also appeared in 83 games with Triple-A Durham on the farm and slashed .258/.361/.497 with an .858 OPS, 20 home runs, 65 RBI and 49 runs scored in 363 plate appearances. Shenton will provide the M's with minor-league infield depth heading into spring training next year after hitting .283/.388/.527 in his five seasons in the minors.

Colt Emerson Swinging A Hot Bat In The Arizona Fall League

Seattle Mariners shortstop prospect Colt Emerson has carried a stellar .370/.435/.537 line across 13 games at the Arizona Fall League. He has also tallied nine doubles, ten RBI, and eight stolen bases. He currently holds the highest AVG out of all shortstops participating. This is a great sign for the former first-round pick as he enjoyed a fantastic extended look at Single-A ball last summer. Across 40 games, Emerson posted a .293/.440/.427 line with 12 doubles. He then earned a brief taste of High-A ball but posted a modest .225 AVG. Dynasty managers should continue to follow his progression as he is considered the top prospect in Seattle and No. 27 overall on MLB Pipeline.

Jorge Polanco Has Knee Surgery, Expected To Be Ready For Spring Training

Seattle Mariners second baseman Jorge Polanco (knee) had surgery to fix the patellar tendon in his left knee and is expected to be ready for the start of spring training in February, according to sources. Polanco has dealt with knee pain in recent seasons and really struggled at the plate in 2024 with the M's while playing through it. The 31-year-old veteran switch-hitter was mainly bothered hitting left-handed, batting .198/.301/.345. Overall, he hit only .213/.296/.355 with 16 long balls and 45 RBI in his first year in Seattle. The surgery should help Polanco get some of his prodigious power back, as well as his lateral movement. Coming off the bad season, it's unknown where Polanco will be playing in 2025, really hurting his all-around fantasy stock. The Mariners have a $12 million club option with a $750,000 buyout and must decide whether to pick it up in early November. After posting a career-low .651 OPS, we'd expect Seattle to decline his option and make him a free agent.

Logan Gilbert Ends Year On High Note

Seattle Mariners starting pitcher Logan Gilbert finished off an excellent season with another strong performance on Sunday, tossing 5 scoreless innings in a 6-4 win over the Oakland Athletics. Gilbert had his way with the A's, allowing just one baserunner (a single) while striking out seven. He finishes the season with nine wins, a 3.23 ERA, a league-leading 0.89 WHIP, and 220 strikeouts in 208 IP. The 27-year-old blossomed into an ace this year and should be one of the first pitchers off the board in fantasy drafts in 2025.

Bryce Miller Won't Make Another Start This Weekend

Seattle Mariners interim manager Dan Wilson said that right-hander Emerson Hancock will be called up from the minors to start Saturday's contest at T-Mobile Park against the division-rival Oakland Athletics, and right-hander Logan Gilbert will take the ball for the season finale on Sunday. The rotation decisions for the team's final two games of the season -- they were eliminated from postseason contention on Friday -- mean that right-hander Bryce Miller won't make another start in 2024. The 26-year-old had a breakout campaign in his second year in the big leagues, going 12-8 with a shiny 2.94 ERA (3.58 FIP), a 0.98 WHIP, 171 strikeouts and 45 walks in 31 starts (180 1/3 innings). He'll cost a pretty penny in fantasy drafts next spring. Hancock, on the other hand, has been very inconsistent and is sporting a 4.72 ERA and 1.30 WHIP with only 36 K's in 55 1/3 frames.

Victor Robles Takes A Seat

Seattle Mariners outfielder Victor Robles is out of the starting lineup ahead of Friday's game against the Oakland Athletics. The Mariners don't have anything to play for anymore after being eliminated from the postseason contention That being said, Seattle has little incentive to play their star players. Mitch Haniger will take over in right field and bat sixth against left-hander JP Sears. Haniger has been bad at the plate this season, but even worse against left-handed pitching, so he can be avoided in all fantasy formats on Friday.

George Kirby Strikes Out Six, Picks Up Win No. 14

Seattle Mariners starting pitcher George Kirby kept his team's playoff hopes alive with six strong innings in Wednesday's 8-1 victory over the Astros, allowing one earned run on four hits and one walk while striking out six on the way to recording his 14th win of the season. It was the 26-year-old's third straight quality start and 20th of the year out of 33 starts. The righty finishes the season 14-11 with a 3.53 ERA, 1.07 WHIP, and a 20.1% K-BB% thanks in part to an elite-level 3.0% walk rate. The 26-year-old has now posted three consecutive seasons of sub-4.00 ERA (and sub-4.00 SIERA) to start his career along with excellent command, proving he's one of the brightest young arms in the game and managers should expect similar results in 2025.

Julio Rodriguez Reaches 20/20 Plateau With Home Run

Seattle Mariners outfielder Julio Rodriguez went 1-for-5 with a two-run home run in Wednesday's 8-1 win over the Astros, keeping the team's playoff hopes alive. The home run was Rodriguez's 20th of the season, earning him his third consecutive 20/20 season to start his career. Despite a slow start to the season, the 23-year-old has rewarded managers who persevered and made the fantasy playoffs with him, collecting a hit now in seven straight games while hitting .336 with seven home runs in September (23 games). Rodriguez and the Mariners will face a familiar opponent this weekend in the A's but will face lefty JP Sears specifically on Friday who the 2x All-Star is just 3-for-19 off of lifetime, including five strikeouts and no extra-base hits.

Luke Raley, Josh Rojas Sitting Against Astros

Seattle Mariners outfielder/first baseman/designated hitter Luke Raley and infielder Josh Rojas are both starting the game on the bench for Wednesday's series finale at Minute Maid Park against the division-rival Houston Astros with a left-hander on the mound. Justin Turner is making the start at first base and is batting fifth, while Dylan Moore will man the hot corner and bat out of the nine-hole against Astros left-hander Yusei Kikuchi. Turner has an RBI and is hitting .273 in 11 career at-bats against Kikuchi, while Moore has gone hitless against the southpaw in five career at-bats. Raley has reached the 20-homer mark for the first time in his career in 2024, but he's also hitting just .192 (14-for-73) with just two of his 21 long balls against lefties. Rojas has been even worse against lefties, going 8-for-58 (.138) with none of his eight home runs on the year.

Logan Gilbert Allows Three Homers In Loss Tuesday

Seattle Mariners starting pitcher Logan Gilbert fell to 8-12 in Tuesday's 4-3 loss to the Astros. Gilbert pitched six innings, allowing four runs on five hits (including three home runs) and a walk with six strikeouts. Home runs have been an issue for the 27-year-old in September, as he allowed eight long balls in five starts and 31 1/3 IP. Gilbert's second half was not as good as his first half, but he will presumably finish the season with a solid 3.33 ERA, a 0.91 WHIP, and a 9.44 K/9 rate in 32 starts and 203 IP. Gilbert proved himself to be a high-floor innings eater this season for fantasy managers and will likely see his fantasy stock rise for the 2025 season.

Bryce Miller Fires Seven Scoreless Innings Monday

Seattle Mariners starting pitcher Bryce Miller continued his dominant second half in Monday's 6-1 win over the Astros. Miller pitched seven scoreless innings, allowing two hits and two walks with five strikeouts. The 26-year-old now has a stellar 2.94 ERA through 31 starts and 180 1/3 IP this season. This has been fueled by his 12 second-half starts, which have resulted in a 5-1 record with a 1.89 ERA, a 0.84 WHIP, and 73 strikeouts in 71 1/3 IP. He is slated to start the final game of the season against the Athletics, so fantasy managers should hopefully have one more opportunity for him to provide them with excellent results as the Mariners push for a playoff spot.

Justin Turner Playing On Sunday

Seattle Mariners infielder Justin Turner (knee) is in Sunday's starting lineup and will cover first base. He will bat in the five-hole. The veteran was lifted from Saturday's game after hitting a foul ball off his knee. The injury does not seem serious as the 39-year-old will rejoin the starting nine. Since September 12, Turner has been carrying an excellent .334/.395/.625 line with three doubles, two home runs, and a 4:10 BB:K ratio. Turner has shown an excellent eye at the plate with a strong 11.0% walk rate and a 17.8% K rate which are both significant above the average marks. Turner is worth a look as a value play in DFS this afternoon given his hot stretch. He will face Houston southpaw Andrew Heaney who carries a 3.89 ERA into Sunday's game.

Emerson Hancock  • SP  •  Mariners

Emerson Hancock Optioned To Triple-A

Seattle Mariners starting pitcher Emerson Hancock was optioned to Triple-A Tacoma earlier on Sunday, according to Shannon Drayer. In a corresponding move, the Mariners promoted Gabe Speier from Triple-A. Hancock posted a 4.50 ERA and a 1.20 WHIP across his previous two starts at the big-league level in September. This move suggests that Luis Castillo (hamstring) could be on his way back from the injured list, as the Mariners now only have four pitchers in their rotation. While Hancock has struggled in the big leagues this summer, he has posted a modest 3.26 ERA, 1.27 WHIP, and a 61:36 BB:K across 88 1/3 frames in the minor leagues.

Julio Rodriguez Stays Hot, Homers Again

Seattle Mariners outfielder Julio Rodriguez continued to hit the ball well on Saturday, going 4-for-6 with a home run, four RBI, two runs scored, and a stolen base in an 8-4 win over the Rangers. It was the second consecutive game with a home run after a two-homer game on Friday, giving him 19 on the season. Over the last eight games, the 23-year-old has gone 18-for-38 (.474) with two doubles, five home runs, 14 RBI, eight runs scored, and a stolen base. It seems he's making up for the power drought he exhibited for much of the season and the former A.L. Rookie of the Year is now just one home run away from a 20/20 season. The 2x All-Star also has his slashline up to a respectable .273/.327/.409 and his newfound production is coming at the most critical time of the fantasy season.

Luis Castillo Could Return Next Week

Seattle Mariners starting pitcher Luis Castillo (hamstring) could return from the injured list as early as September 23. The team remains optimistic their 31-year-old ace could be activated after a minimum stay on the 15-day injured list. Castillo hit the IL with a hamstring strain on September 10. Manager Dan Wilson did not express much detail about his progression, but seeing that the team remains optimistic is a promising sign. Before the injury, Castillo held a 3.64 ERA, 1.17 WHIP, and a 47:175 BB:K ratio across 175 1/3 innings of work this summer with an 11-12 record. If Castillo returns next week, fantasy managers should expect right-hander Emerson Hancock to drop out of the rotation.
