The Seattle Mariners, having one of the best collections of young talent in the minors, boast one of the more stacked Spring Breakout rosters.
While these games are simply minor league all-star contests, they offer fans a glimpse of the kids on their favorite teams, and the Mariners have plenty to brag about.
Seattle takes on Cleveland at Goodyear Ballpark Friday at 1:05 pm PT, which you can watch locally on the club’s RSN through the usual options.
Fans should get their first look at right-handers Jurrangelo Cijntje (No. 3 in my 2025 Prospect Rankings) and Ryan Sloan (No. 7), the club’s first two selections in last year’s draft.
Cijtnje is a switch pitcher with a chance at No. 2 status as a righty. How or if the club attempts to extract value from him as a southpaw remains to be seen. He’s a four-pitch starter with athleticism and projectable command. When ramped up he pitches comfortably into the mid-90s and has hit 99 mph.
Sloan is built like a rotation anchor and is a master manipulator of the baseball. He runs and cuts his fastball to set up a budding slider and a flashing-plus changeup.
Jeter Martinez (No. 20), a 19-year-old with all the physical tools to develop into a mid-rotation or better starter, is also on the roster and should get an inning or three; Mid-90s, feel for a changeup, slider, athleticism, it’s all there. Control has been an issue early, but he’s a fun watch and the org has plenty of time to work with him.
Brandyn Garcia (No. 14), Hunter Cranton (No. 17), and Brock Moore (No. 26) are among the pure relievers on the roster. Cranton and Moore live in the mid-90s, with Cranton’s heater projecting big value and Moore’s slider showing huge potential as a bat-missing pitch. Garcia has a great shot to see the majors in 2025 with his 92-97 mph fastball and sweeping slider.
Right-hander Charlie Beilenson (No. 33) was the Mariners’ fifth-round pick last July and brings three secondaries to pro ball to back up a fastball 92-96 mph. He used both a slider and cutter in college, but the swing-and-miss came from the changeup.
Grant Knipp (No. 39), a two-way prospect who likely gets time at first base and/or DH while he chases his arm strength into a potential late-blooming relief role, will also be on display in this game. He has power and has touched 95 mph from the mound.
Most fans are familiar with Harry Ford (No. 6), but Josh Caron (No. 21) is an intriguing backstop with power and athleticism after the club made him their fourth-round selection last summer.
Colt Emerson, Cole Young, Felnin Celesten, Michael Arroyo, and Tai Peete aren’t new to most fans, but Celesten hasn’t been on TV much, and Peete has a new position in center field.
Emerson has the best swing in the organization, and Young is on the brink of the majors. However, every chance I get to check in on Arroyo’s defense at second is worth my time. If he can stick there, he’s a future 55 with solid trade value.
Peete drew role comps from Russell Branyan to Adolis Garcia from me this winter, but if he takes well to center may be more like Devon White.
Brock Rodden (No. 45) has a chance to be a multi-position reserve in the big leagues. Luis Suisbel’s trouble making contact was half of the reason he fell off my Top 50 — the other half is a deep, risk-reward combo of additions to the farm system — but there’s no denying his raw power. He’s a decent switch hitter but he’ projects to first base only and hasn’t reached High-A yet. Suisbel will be 22 in May.
Lazaro Montes (No. 8) is a fan favorite, and while he’s a bat-only prospect it’s 70 raw power and he earned his way to Everett last summer at age 19 by improving his swing-and-miss rate in Modesto. It’s imperative that Montes not only avoid chasing as much as possible but also avoid missing opportunities to punish in-zone fastballs.
Carlos Jimenez is unranked by everyone else (most only rank 30 players), but I have him at No. 31 and loved what I saw as I followed Modesto to San Jose last summer. He can run a bit and has a chance to stick in center, and his gap power and plate skills suggest a shot at a bench role down the line. He just turned 22 and should see Everett to open the season.
