It’s that time of year again!
After a busy offseason of transactions that’s seen several top prospects shipped out for controllable talent, the Mariners farm system looks substantially different than it
did at the end of last year. Despite plenty of graduations over the course of last season and a healthy amount of trades that sent prospect talent out the door, Seattle still finds themselves with one of the more promising crops of young talent across the league and remain amongst the upper tiers of farm systems league-wide. It’s perhaps not at the elite level it once was, but assuredly above average.
Our annual prospect rankings begin today with Part One of our honorable mentions: The Bats. (Part Two, The Arms, will drop on Thursday.) We’ll be sharing writeups on our top twenty players every Tuesday and Thursday, thoroughly analyzing our favorite prospects and sharing why we’re bullish on their futures. These rankings are a composite of our own personal rankings and aim to reflect the average view of our sitewide prospect team. If you disagree, please let us know (nicely) in the comments!
Brock Rodden – UTIL
2025 Statistic of Note – .342/.405/.526 in AZ Fall League
Rodden has been in the organization for a few years now, routinely finding his way inside of our top twenty rankings. Unfortunately, after an injury-marred season that saw him garner under 200 PA’s, we had him fall just outside of our list this season. When on the field, Rodden has done nothing but produce. The switch-hitting utility man has collected a minor league Gold Glove for his play at second base and has far more power than his 5’7 frame might have you think. He’s sneakily been one of the most consistent performers in this entire system, and despite his relatively advanced age compared to other prospects (he’ll be 26 in March), there’s plenty of reason to believe he can provide the team with a do-it-all utility infielder sometime soon. If the bat to ball skills come back down a little to his career norms, I’d expect Rodden to be a viable option to serve in a fill-in role, a la Leo Rivas or Dylan Moore.
Grant Jay – C/OF
2025 Statistic of Note – Has not debuted
A muscled-up free swinger with a boatload of power, Grant Jay is a super intriguing bat drafted in the 12th round of the 2025 MLB draft. With some legitimate buzz around his name entering the year, Jay went on to slash .309/.437/.655 as a junior for the Dallas Baptist Patriots and was one of the key cogs in the middle of a super talented lineup. Snagging 14 bags as a catcher provided further intrigue to the strong-armed catcher as well, seemingly giving him a ton of tools for teams to dream on at a premium position. What’s not to like?
For starters, Grant Jay’s hit tool is quite poor. Striking out 25.6% of the time in college isn’t necessarily a death sentence, but that’s a pretty significant sign of serious bat-to-ball issues. Additionally, Jay’s defensive future is a little unclear at the moment. Playing primarily as a catcher throughout his college career, most evaluators seem to have him moving off the position moving forward, likely into a corner outfield spot. He’s tremendously strong and a good athlete, but it’s not always super fluid out there and there’s concern he’s a tweener defensively. If he can’t provide passable defense behind the plate, a high-whiff corner outfielder is a far less desirable player and is likely the reason why he ended up slipping to the 12th round. Regardless of his draft position, Jay is absolutely one to watch. He’s far more talented than a lot of players that were taken ahead of him.
Grant Knipp – C/RHP
2025 Statistic of Note – DNP
One of, if not the most unique player in this entire system, Grant Knipp was drafted in the sixth round of the 2024 draft out of Campbell as a two-way player. Though unproven on the mound, he’s been clocked up to 98 from the right side and showed off promising raw shapes with his slider and cutter alike. Perhaps even more interestingly, Knipp was leading the country in homers before he went down with an oblique injury midway through the season and has truly tremendous raw power at the dish. His .402/.547/1.029 slash through his first 29 games (that’s a 1.576 OPS!) is an obviously astronomical accomplishment that shows just how promising a player Knipp is, though it doesn’t come without some clear concerns to his game. Swing-and-miss is going to be a major part of his game as a professional, and having only logged 5.2 IP in his life, to say he’s a little raw on the mound is an understatement. We’re yet to see Knipp take the field as a professional just yet, but with the level of athleticism he possesses, his debut is sure to be an exciting one.
Aiden Taurek – OF
2025 Statistic of Note – .336 AVG | 16/12 K/BB
Aiden Taurek probably isn’t a player most are familiar with, but the young outfielder showed a surprising amount of promise in the early days of his professional career that has him on prospect radars for 2026. Coming out of Saint Mary’s in California from last summer’s 2025 draft, the 13th rounder did nothing but spray the ball all over the Modesto ballpark and looked like an extremely professional hitter from the right side of the plate. There hasn’t been much power in his game thus far and it’s a corner outfield profile, but the contact ability has been phenomenal, the plate discipline is certainly present, and he’s been successfully aggressive on the basepaths. It’s probably not going to be an insanely dynamic prospect that headlines prospect lists, but Taurek looks like he’s got a shot to be a productive piece of this system. He’s got to get to more power in-game, but after his strong debut, he’s undoubtedly turned himself into a piece you’ll want to keep an eye on.
Victor Labrada – OF
2025 Statistic of Note – 151 wRC+ in 300 PAs at AA; 0.88 BB/K
After a long, slow climb through the minors, the fun-sized Cuban has finally landed in Tacoma. Labrada has been a bit of a slow mover since debuting in 2021, needing to repeat levels at times, especially early in his career, but he figured out Double-A this year and is on his way to solving Triple-A. One of the better stolen base threats in the minors, he swiped 44 bags last year and could be an option if the team needs a speedster later in the season, provided he can continue his Oops! all OBP approach in the box.
Leandro Romero – SS
2025 Statistic of Note – 9 HR across 180 PA in DSL
Joining the Mariners as a raw, unpolished 17 year old in the 2024 IFA class, Romero struggled adjusting to the uptick in opposing talent and had a disappointing season. Returning to the DSL for a second round, Romero flipped the script entirely and dominated the competition all season, ultimately changing his prospect outlook entirely. The athletic shortstop displayed good power and improved plate discipline in his retread of the DSL, pairing it with above average marks for his defense on the dirt. It’s a power-over-hit profile, but with extremely advanced exit velocities for his age and exciting tools everywhere else, the hit tool might not need to be all that good for this kid to be an impact player. Romero is a super talented player that should be on everyone’s radar for the 2026 season.
Check back in on Thursday for part two of our honorable mentions!
