The Mariners are getting a fresh batch of talent into their high performance camp in Arizona, and the club announced 36 players will take part in the program Wednesday.
Seattle’s group is split between 22 position players and 14 pitchers. It also includes 14 of the 18 players the Mariners signed from their 2026 draft class, along with three players from their 2026 international free agent class. On top of that, 18 of the players are ranked among the organization’s top 30 prospects by MLB Pipeline.
Several of the bigger names on the list stand out immediately: shortstop Felnin Celesten, catcher Luke Stevenson, third baseman Ace Reese, outfielder Yorger Bautista and left-handed pitcher Mason Peters.
The full camp roster is heavy on players who sit high in the system, with a long list of arms and position players set to keep working in Arizona. Among the pitchers are Lucas Kelly, Colton Shaw, Mason Peters, Casey Hintz, Jack Bowery, Po-Chun Lin, Nathan Taylor, Connor Mashburn, Matthew Matthijs, Chris Torres, Isaac Thornton, Christian Little, Jackson Steensma and Wyatt Queen.
The position-player group includes Celesten, Stevenson, Aiden Taurek, Nick Becker, Ace Reese, Henry Ford, Ryan Wynn, Jake Brown, Hayden Yost, Bautista, Eric Jeon, Trevor Lucas, Mason Eckelman, Kelvin Alcantara, Leandro Romero, Manuel Almeida, Juan Rijo, Gregory Pio, Jarvis Gomez, Charlie Sutherland, Josh Caron and Diego Contreras.
The Mariners Player Development account noted the camp was underway in Arizona as players continued to sharpen their skills and improve their game.
Over in the Arizona Fall League, Seattle has eight players with the Peoria Javelinas, but the first half of the 30-game season has been a quiet one for the group.
Catcher Boston Smith, the club’s 13th-ranked prospect, has had the toughest time getting rolling. The 23-year-old, acquired from the White Sox in August in the Luis Castillo trade, is batting .156 with a .473 OPS, no extra-base hits, eight walks and 14 strikeouts in 10 games.
Brandon Eike, 25, who turned in a strong year with High-A Everett, is batting .229 with a .594 OPS, two doubles, four walks and nine strikeouts in 10 games.
Among the five pitchers Seattle sent to the AFL, right-handers Ty Cummings and Adam Smith have produced the best numbers so far. Cummings, 24, has given up two runs on four hits and two walks while striking out six over 4 2/3 innings in five appearances. Smith, 26, has allowed one run on two hits and struck out four over 3 2/3 innings in four appearances.
One former Mariners prospect has been much louder with the bat for Peoria: Tai Peete. The 21-year-old is hitting .341 with a 1.060 OPS, one homer, three doubles, three triples, six walks and 12 strikeouts in 10 games.
Peete was dealt to the St. Louis Cardinals in February in the trade that brought Brendan Donovan to Seattle.
Peoria is in fourth place in the six-team AFL at 8-7 through the first half of the schedule. The league’s regular season ends Wednesday, Nov. 11, and the playoffs run Nov. 12-14.

Mariners Manager Search Just Got Tougher For One Big Reason
The Angels managerial opening has added another wrinkle to the Mariners search for a new skipper, with one of the most recognizable jobs on the West Coast suddenly back on the market. Kurt Suzuki is out after a single season in Anaheim, where the team struggled through a rough year and spent plenty of time dealing with injuries, leaving the Angels needing a reset at the top.
For Seattle, the timing matters because the Angels job has its own appeal, from the market to the organizational spotlight that comes with managing in Southern California. The situation is only more complicated with a change in ownership on the horizon, and that could make the vacancy even more attractive to the kind of candidates the Mariners are trying to evaluate.

Mariners Search Just Raised A Big Question About This Roster
The Mariners managerial search has taken another turn, and it says as much about the organizations priorities as it does about the candidates themselves. Along with more familiar names such as Joe Espada and Rocco Baldelli, the club is also interviewing Jason Kanzler, the Cubs director of player development, adding a different type of voice to the mix as Seattle weighs its next move.
Kanzlers path is rooted more in minor league work and player development than in big-league dugout experience, with stops in the Astros and Cubs organizations shaping his rsum. For a Mariners club that has spent plenty of time trying to blend young talent into a contending roster, that background makes him a relevant option even if it also raises the obvious question of what kind of manager Seattle really wants leading this group.

Mariners Search Just Took A Turn Fans Didn't See Coming
The Mariners managerial search has taken a slightly different shape in recent days, with Jason Kanzler emerging as a serious candidate for the opening. Kanzler is currently the Chicago Cubs director of player development, and his background has drawn attention because it blends coaching, analytics and hands-on work with young talent. He also has previous coaching experience with the Astros, where he worked closely with players such as Jeremy Pena and Alex Bregman.
For Seattle, the appeal is pretty clear. The next manager will inherit a roster that mixes established veterans with younger pieces still trying to settle in, and that kind of bridge role can matter as much as dugout experience. Kanzler fits the profile of an instructor and evaluator, though he does not bring major league managerial experience to the table, which makes him an intriguing name as the process moves forward alongside Joe Espada and Rocco Baldelli.
