Re-ranking the Seattle Mariners' top 10 prospects after 2025 MLB Draft

After the 2025 MLB draft, where do the Seattle Mariners' top prospects fall in an updated rankings?

While we won't see new draft picks ranked by MLB Pipeline until the end of the summer, we can always speculate where they might slot into. For now, here is a projected update of the Mariners' top 10 prospects.

Note: Because Cole Young is 12 major league at-bats from losing his rookie eligibility, he is not included in this list.

How the Mariners' top 10 prospects rank after 2025 MLB Draft

1. Colt Emerson, SS

Ranked by MLB Pipeline as the No. 17 overall prospect and the sixth-best shortstop prospect in the game, Emerson is not going anywhere. He has the highest floor of any Mariners' prospect. While he may not have the power tool of Lazaro Montes or the ambidextrousness of Jurrangelo Cijintje, Emerson has the broadest set of skills.

2. Lazaro Montes, OF

Montes climbed into the MLB's top 30 prospects in the latest update on MLB Pipeline, which ranked him No. 28. The 20-year-old has a power tool of 65, and has drawn frequent comparisons to superstar Yordan Alvarez. If Montes can perform anywhere near the level of Alvarez, he will be a mainstay in the Mariners' lineup for years to come.

3. Felnin Celesten, SS

The prize of Seattle's 2023 international crop of talent, Celesten is just 19 and already bursting into prospect rankings. MLB pipeline ranks him No. 53, despite a lack of results so far in Single-A Modesto. Celesten has the potential to be a five-tool player and might have higher upside than any other prospect in the organization if he can reach his ceiling.

4. Harry Ford, C

Ford has been playing well in Triple-A for the past two months and has regained his status as one of the top catching prospects in baseball. The former first-round pick is ranked No. 55 on MLB Pipeline and should be in the major leagues soon.

5. Kade Anderson, LHP

The Mariners' 2025 first-round pick immediately slots in as the fifth-best prospect in the farm system, and he will have the potential to climb rapidly. Anderson was regarded as the top college arm in the 2025 draft and at times resembled a left-handed Paul Skenes at LSU. If there is more to be unlocked in the 21-year-old, the Mariners' pitching development lab will surely find it.

6. Michael Arroyo, INF

Arroyo has mashed at every level of the minor leagues so far, which has helped him rocket up prospect boards. He put together a .934 OPS in 65 games at High-A Everett this spring, earning a call-up to Double-A Arkansas. There, he has actually hit slightly better with a .953 OPS. Although he is not ranked as highly as other infield prospects, Arroyo continues to play like he should be the team's top prospect.

7. Jonny Farmelo, OF

Farmelo has not played much in the Mariners' minor league system because of injuries, so it's hard to judge where he deserves to be ranked. MLB Pipeline ranks him No. 65 overall, one spot behind Arroyo. The results have been good so far. The 2023 first-rounder had a .819 OPS in 46 games at Modesto last year. This year, the 20-year-old has played 15 games at Everett with a .958 OPS.

8. Ryan Sloan, RHP

The Mariners' second-rounder in 2024 has looked good in his first season of minor league baseball. The 19-year-old holds a 3.62 ERA across 14 starts at Modesto, with 61 strikeouts against only 11 walks in 54.2 innings.

9. Jurrangelo Cijntje, RHP/LHP

The two-handed pitcher has struggled in the minor leagues this year, but still possesses an incredibly unique ability. He is ranked No. 78 on MLB Pipeline despite a 4.95 ERA in High-A, though he did put on an impressive display in the Futures Game.

10. Nick Becker, SS

Becker was the Mariners' second-round selection in 2025. The prep shortstop hit .407 over 95 career high-school games and put together a 1.251 OPS. He is seen as an above average hitter and should add pop as he grows into his 6-foot-4 frame.
