Beneath is an evaluation of the prospects within the farm system of the Seattle Mariners. Scouting stories have been compiled with info supplied by business sources in addition to my very own observations. That is the sixth yr we’re delineating between two anticipated reduction roles, the abbreviations for which you’ll see within the “place” column under: MIRP for multi-inning reduction pitchers, and SIRP for single-inning reduction pitchers. The ETAs listed usually correspond to the yr a participant must be added to the 40-man roster to keep away from being made eligible for the Rule 5 draft. Guide changes are made the place they appear acceptable, however we use that as a rule of thumb.

Different Prospects of Observe
Grouped by kind and listed so as of desire inside every class.
Depth Arms With a Sprint of Upside
Po-Chun Lin, RHP
Chia-Shi Shen, RHP
Charlie Beilenson, RHP
Peyton Alford, LHP
Jimmy Joyce, RHP
Lin is a wild card. Signed out of Taiwan for $460,000 within the 2025 worldwide interval, he’s wholesome now after not pitching in video games after signing. There’s some push and pull all over the place in his profile. He’s touched the mid-90s however sits a lot decrease. He’s athlete with physique management but in addition a violent supply. He was as soon as a two-way participant and now has two changeups. There’s simply much less identified about him than just about anybody else on this listing, to the purpose the place I didn’t really feel comfy giving him a full profile. Signed out of a Taiwanese semi-pro league, Shen has nice physique management and somewhat deception from how lengthy he holds on to the ball. He has a pleasant changeup, however the stuff is in any other case fringy. Beilenson’s mix of 70 management, common stuff, and below-average command is an uncommon, dinger-prone combine. He might actually use one other tick or two, as his low-to-mid-90s fastball performs under the quantity. I’m skeptical Alford’s fastball will proceed lacking bats prefer it has towards mid-minors competitors, however he’s left-handed and has two above-average breaking balls, so he might discover his manner into the combination finally anyway. Joyce as soon as regarded like a believable backend starter prospect. He’s sputtered within the higher minors and is out till at the least July with the shoulder damage that sidelined him final spring.
DSL Guys
Leandro Romero, SS
Elias Perez, OF
Manuel Almeida, C
Kendry Martínez, IF
Romero signed for $1 million within the 2024 worldwide class. He’s an uber-projectable shortstop who hit significantly better throughout his second spin by means of the DSL, however I don’t love his swing. He’s probably the most attention-grabbing place participant within the Others of Observe part. Perez bought $600,000 within the 2025 class and performed heart when Yorger Bautista wasn’t on the market. He’ll both want to chop down on his swing size or get loads stronger, however he has a plan and might hit somewhat bit. I’m involved he could mature early bodily. Almeida is a catcher with pop however a poor glove presently, and regardless of yr total, his lack of contact was regarding given the extent. Martínez signed for $2.5 million previous to the 2025 season, however his first professional marketing campaign was a catastrophe.
Undersized Older Signees Out of Mexico
Juan Cazarez, RHP
Francisco Pazos, RHP
Angel Chicuate, RHP
Maximo Rodriguez, RHP
Cazarez runs his heater into the mid-90s. He has a pleasant supply and might spin it a bit, however he’s a stiffer athlete. He isn’t lacking a ton of bats in a size position, however he might need the best reduction ceiling on this group. The square-bodied Pazos touches 95 and has some really feel to throw strikes and spin the ball. Fashions appear to love him greater than scouts. Chicuate is small and barely threw final yr, however he touched 96 with attention-grabbing pitch knowledge. Rodriguez, now 20, was signed out of the Mexican League, the place he threw a handful of innings as an 18-year-old. Befitting a man who was teammates with greater than a dozen former huge leaguers, he’s polished for his age. He’s a misleading sinker-slider man who generates big tail and sink on his two-seamer, and pairs it with a reasonably good breaking ball. He sits both facet of 90 and isn’t bodily projectable, however the story is nice sufficient to flag, and there are many guys who’ve turned worse elements into up-down careers.
Outfielders, Largely From the Higher Ranges
Rhylan Thomas, OF
Spencer Packard, LF
Victor Labrada, LF
Jared Sundstrom, OF
Carlos Jimenez, CF
Thomas debuted in 2025. He’s a sprig hitter with beautiful really feel for contact and the strike zone, however I’d be rounding as much as get him to 30 energy and that’s a killer. I’m curious to see if he might hit .400 in Korea. Packard has method, and a brief swing helps him put seemingly every little thing in play. The contact isn’t very agency, although, and he’s under common in a nook. I’m skeptical he’ll make it work in the long term, however maybe he can hit .275 for a stretch and provides the large league membership a complementary line-mover amidst all the ability bats. One other Triple-A tweener, Labrada can hit somewhat, however he has a bunch of 40s all over the place else on the cardboard. Sundstrom is an effective athlete with tweener instruments and an aggressive method that caught up with him in Double-A. A Low-A repeater, Jimenez is an effective athlete with common energy and above-average velocity however a 30 bat.
Strolling in Reliever Wonderland
Grant Knipp, RHP
Michael Hobbs, RHP
Brock Moore, RHP
Stefan Raeth, RHP
Elijah Dale, RHP
Emphasis on the “strolling.” Knipp was a two-way participant at Campbell. He solely pitched in 4 video games there, however he touched 100 mph on the 2024 Mix. He had TJ simply earlier than the 2025 season; we’ll see what it seems like in 2026. Hobbs spins a plus curve and has an attention-grabbing mixture of stuff in addition to. The hassle in his supply is such that I wince in sympathy on each pitch; we want not name the Hardy boys to determine why he walks individuals. Moore touches triple digits and his slider flashes plus, however he’s a stiff athlete with an enormous head whack and larger management issues. Raeth is making an attempt to grow to be the newest Washington Husky to play for the Mariners. He’s a spin-to-win righty who leans on his sweeper. He discovered somewhat additional gasoline in 2024, which breathed life into a man who regarded like an org arm earlier in his profession. Dale’s really feel to spin a tough sweeper with in any other case 30-grade velocity is an outlier trait; possibly it may be molded into one thing helpful.
Backstop Backstops
Grant Jay, C
Josh Caron, C
Jay has good palms, a robust arm, and appears like a heads-up defender behind the dish. His bat is horrifying, although. He’s bought energy but in addition a bottom-hand dominant swing with a steep path and a ton of swing and miss towards fringy competitors. He might be a backup. Caron has the instruments to be a bat-first catcher, however his aggressive method was annihilated by A-ball arms.
System Overview
That is probably the most stratified system within the sport. As Eric wrote final yr, most farms this skinny are among the many worst in baseball, however Seattle’s isn’t simply good, it’s nice. Groups covet bats above all else as of late, and the Mariners have 5 within the 50 FV tier or higher, even after buying and selling Harry Ford and graduating Cole Younger. They’ve one low-variance 55 in Colt Emerson, with a number of attainable stars lurking behind him. In the event that they get two two-plus-win regulars out of that group, it’ll be an enormous shot within the arm for the large league membership. If even half the 50s meet their projection, they’ll seemingly be annual pennant contenders.
Stars and scrubs is a dangerous solution to construct a farm system, and we usually favor a extra diffuse spending method, significantly in Latin America. The Mariners are the league’s finest counterpoint to that philosophy. Even with a whiff right here and there (Dawel Joseph signed for $3 million and should by no means escape the complicated), Seattle’s success fee on big-dollar signees could be very excessive. The scouting and dev system deserves a ton of credit score for focusing on elite and malleable expertise, and has greater than earned the good thing about the doubt with respect to the way it operates. Whenever you hit like this in your huge swings, there’s no motive to dial issues again.
Unusually for a membership that scouts and develops so effectively, there are a whole lot of org guys filling area on the farm. For a participant dev group that has succeeded in a number of other ways with numerous pitchers — assume George Kirby’s velo spike, Bryce Miller’s cut up, Logan Gilbert’s evolving pitch combine and method, stretching out Logan Evans, discovering a decrease slot for Tyler Cleveland, and many others. — there’s a cookie-cutter really feel to the system’s depth items. So many arms flip into spin-to-win sweeper monsters, oftentimes with decrease slots on their breakers than the warmth in a manner that’s by no means going to idiot high quality hitters. Seattle has additionally punted on a few alternatives to gather depth on the place participant facet. The Mariners solely have one DSL crew, and many of the ACL lineup was hilariously outdated and tool-less for the extent. Up and down the system, there are many gamers with out projectable instruments, lots of whom have caught round longer than they’d have for different groups. This isn’t a criticism, simply an statement and maybe an inevitability with all of the over-slot signees Seattle has prioritized. The form of the system could also be uncommon, but it surely’s a lot purposeful.
