Top 30 Seattle Mariners Prospects For 2024 Dynasty Leagues

By Richard Haake
Top 30 Seattle Mariners Prospects Rankings

The next team up in our 2024 Organizational Prospect Rankings is the Seattle Mariners. This is a farm system that has really taken huge steps forward over the last five seasons, developing pitchers like George Kirby, Logan Gilbert, Bryce Miller, and Bryan Woo in addition to many more. It’s from this development in the farm system that the Mariners have been able to come off prospects like Connor Phillips and Noelvi Marte to bolster their major league club and not compromise the future. In this article, we will do a deep dive into the top 10 Mariners prospects and fully list out the top 30. I am positive you will find there is a lot to like with the Mariners prospects.

If you aren’t playing your dynasty leagues on Fantrax, you’re missing out on the deepest player pool and most customization around. Just starting out in a dynasty league? Then check out Rick Haake’s Top-400 Overall Fantasy Prospects and George Bissell’s Top-500 Dynasty League Rankings.

Top 10 Mariners Prospects

Harry Ford, C

(118 GP, .257/.410/.430, 15 HR, 89 R, 67 RBI, 24 SB)

Coming in at the top of the Mariner’s prospect rankings is Harry Ford. The 20-year-old Ford has a solid season in High-A Everret in 2023, slashing .257/.410/.430 with 15 home runs, 89 runs scored, 67 RBIs, and 24 stolen bases in 118 games. At the plate, Ford took a disciplined approach walking 18.3% while only striking out 19.4% in 563 plate appearances.

Harry Ford profiles as a solid dynasty catcher long-term with an advanced bat who should get to 20-HR power annually. The addition of speed at least in the early years makes Harry Ford even more of a dynasty asset as he could stick to the 20-plus stolen base upside once he debuts.

Colt Emerson, SS

(24 GP, .374/.496/.550, 2 HR, 27 R, 13 RBI, 8 SB)

It is quickly spreading but Colt Emerson might be one of the best prospects available in FYPD this season, ranking up there with Crews and Jenkins. Emerson impressed right out of the gates, slashing .536/.629/.786 with one home run, 10 runs scored, five RBIs, and four stolen bases in eight games played at the Mariners complex after the draft. The results were so good the Mariners promoted Emerson to Low-A Modesto where he continued to hit. In 16 games played with the Nuts, Emerson slashed .302/.436/.444 with one home run, 17 runs scored, eight RBIs, and four stolen base with a stellar 13.9% walk rate and 17.7% strikeout rate across 79 plate appearances.

The upside is massive with Emerson who has already started skyrocketing up dynasty rankings after the MLB draft. There is a plus hit tool here with an extremely advanced eye at the plate leading me to be confident in a high average and OBP contributor long term. I’m curious how Emerson will fill into his 6’1” frame muscle-wise as reports I’ve read say he won’t get to average power. I would say he will get to at least average power between 10-15 HR power as he matures. There might be some stolen base upside with Emerson but that wouldn’t be his calling card for dynasty long-term in my opinion. Emerson is an all-around solid prospect to build a dynasty team around.

Cole Young, SS

(126 GP, .277/.399/.449, 11 HR, 92 R, 62 RBI, 22 SB)

There is a lot to like about Cole Young, and coming into his first full season of pro ball he did nothing but impress. Young started the season in Low-A Modesto where he slashed .267/.396/.429 with five home runs, 60 runs scored, 39 RBIs, and stole 17 bases in 78 games played. His walk rate of 14.4% was higher than his strikeout rate of 13.8% across 376 plate appearances. This success encouraged the Mariners to promote the 19-year-old to High-A Everett. Once with the AquaSox, Young slashed .292/.404/.479 with six home runs, 32 runs scored, 23 RBIs, and five stolen bases in 48 games.

This is one of the best shortstop prospects to stash in dynasty right now because of the advanced approach. With Young, you are getting a player who will hit for average while walking at a high clip and ultimately helping your OBP. There is solid pop and speed here as well so Young could potentially be a 20 home run bat with a 25-30 stolen base upside once he gets established in the major leagues.

Lazaro Montes, OF

(70 GP, .303/.440/.560, 13 HR, 58 R, 61 RBI, 2 SB)

Lazaro Montes appears to be a rising star in the making and has the build and skills to be a difference-maker in the major leagues. Montes played at the complex as well as Low-A Modesto during the 2023 season. At the Mariners complex Montes slashed .282/.452/.555 with six home runs, 31 runs scored, 31 RBIs, and had one stolen base in 37 games. Montes was patient at the plate as he had a 22.6% walk rate while striking out 25.3%. The Mariners then promoted Montes to Low-A Modesto where he slashed .321/.429/.565 with seven home runs and 30 RBIs.

Montes is an exciting player to stash in dynasty leagues of any size mainly because of the massive power and upside. Montes is filling into his 6’3” frame and could get to big-time power with a projection between 30-40 home runs once at the major league level. One slight concern with Montes is the strikeout rate, while not terrible at this point around 25%, I’m curious as to how he will handle advanced pitching as he rises through the system and if that will slow him down at all.

Gabriel Gonzalez, OF

(116 GP, .298/.361/476, 18 HR, 78 R, 84 RBI, 10 SB)

The Mariners have done a solid job scouting and developing international signees over the past six seasons. Gabriel Gonzalez is quickly standing out and climbing up the levels of the minor leagues. In 73 games at Low-A Modesto, Gonzalez slashed .348/.403/.530 with nine home runs, 51 runs scored, 54 RBIs, and eight stolen bases. Gonzalez walked 6.9% while striking out just 13.7% in 335 plate appearances with the Nuts. The Mariners then promoted Gonzalez to High-A Everett where he struggled with the bat slashing just .215/.290/.387 and had an extremely low BABIP of .233.

Regardless of the struggles in High-A Everett, Gonzalez still hit for power, crushing nine home runs and walking at a 6.5% rate, close to his career average. Although the strikeout rate jumped to 21.5% I’m not concerned Gonzalez might have been pressing as the low BABIP indicates he was getting unlucky. Look for Gabriel Gonzalez to bounce back at High-A in 2024 and make the jump to Double-A Arkansas in short order.

Jonatan Clase, OF

(129 GP, .242/.353/.449, 20 HR, 102 R, 68 RBI, 79 SB)

The steady rise of Jonatan Clase has him close to making it to the major leagues. The 21-year-old played at High-A and Double-A in 2023 where he slashed .242/.353/.449 with 20 home runs, 102 runs scored, 68 RBIs, and swiped 79 bases in 129 combined games. At every stop in the minor leagues, Clase walked at a high clip. While in High-A, Clase walked 17% and 13.1% after the bump to Double-A Arkansas. It was with the Travelers that the strikeout rate jumped to its highest yet of 28%.

If Jonatan Clase can get the strikeout rate back down to his career average of 26.4% and get the average back up to .260-.270 he could stick at the top of dynasty rankings. There is potential for plus power and we have already seen the plus speed in action this makes Jonatan Clase a solid target for dynasty leagues.

Felnin Celesten, SS

(Did Not Play In 2023)

Going into the 2023 season many were excited to see one of the biggest names signed in the 2023 international signing Felnin Celesten. Unfortunately, a grade 2 hamstring strain kept him from making his debut. Scouts say there is an advanced hit tool with Celesten, paired with plus speed potential. Smooth defensive skills and a strong arm at shortstop could keep Celesten there long-term. All eyes will be on Felnin Celesten in 2024 as he makes his pro debut.

Tyler Locklear, 3B

(85 GP, .288/.405/.502, 13 HR, 51 R, 52 RBI, 12 SB)

The Mariners had Tyler Locklear play the 2023 season in High-A Everett and Double-A Arkansas. While in Everett, Locklear slashed .305/.422/.549 with 12 home runs, 40 runs scored, 44 RBIs, and 10 stolen bases in 61 games with the AquaSox. Locklear showed a disciplined approach, walking 13.1% while striking out just 21.8% of the time. Locklear was then promoted to Double-A Arkansas where he played 22 games with the Travelers slashing .260/.383/.403 with one home run, 11 runs scored, eight RBIs, and two stolen bases. The walk rate remained strong at 11.7% and the strikeout rate improved to 14.9% in Locklear’s 94 plate appearances.

Long-term for dynasty purposes Locklear has upside as a high-contact third base prospect who will hit for average and OBP with solid pop at the plate. Does this profile sound familiar to Mariners fans? Very similar to Kyle Seager with the bat but might hover around 15 to 20 home runs.

Michael Arroyo, INF

(61 GP, .255/.403/.400, 3 HR, 48 R, 28 RBI, 8 SB)

Early results for Michael Arroyo are promising. Arroyo had a solid season in 2022 in the DSL and followed that up by playing 57 games in Low-A Modesto. While with the Nuts Arroyo slashed .234/.389/.373 with two home runs, 45 runs scored, 23 RBIs, and stole five bases. If the average gives you pause it’s understandable but I will say Arroyo showed solid plate discipline walking 13.6% while only striking out 20% in 265 plate appearances.

It’s still too soon to say Arroyo is going to be a top prospect but there are signs pointing in the right direction. If Arroyo can raise the batting average I believe we could be looking at a solid middle infield prospect who could get to average pop and plus speed long-term.

Ryan Bliss, SS/2B

(128 GP, .304/.378/.524, 23 HR, 110 R, 86 RBI, 55 SB)

The former Auburn Tiger had a big season in 2023 with both the Diamondbacks and Mariners organization. In 68 games with the Amarillo Sod Poodles Bliss slashed .358/.414/.594 with 12 home runs, 67 runs scored, 47 RBIs, and swiped 30 bases in 38 attempts. The Diamondbacks promoted Bliss to Triple-A Reno where he struggled in just 13 games played to get his footing slashing just .196/.274/.357 before being traded to Seattle. Once with his new organization Bliss came around finishing the season with a .251/.356/.466 with 10 home runs, 37 runs, 35 RBIs, and stole 24 bases in Triple-A Tacoma.

Bliss has upside in deeper dynasty leagues as a prospect who could get some run with the Mariners in 2024. There is 20-40 potential here with Bliss if given the opportunity to play every day in the big leagues.
