After advancing to Game 7 of the American League Championship Series in 2025, the Seattle Mariners are squarely focused on getting back to the playoffs in 2026.

However, as a self-admitted 'draft, develop and trade' organization, the M's also have to have a keen eye on their farm system and player development processes. 

And with homegrown players like Julio Rodriguez, Cal Raleigh, Cole Young, Logan Gilbert, Bryan Woo, Bryce Miller, George Kirby and Matt Brash playing critical roles, the M's have done a pretty good job in that department.

And those processes will only continue to be heightened as Kade Anderson, Ryan Sloan, Lazaro Montes, Michael Arroyo and Colt Emerson work through the system. Several of those players could debut as early as this year.

But, after trading away top prospects Tai Peete, Jurrangelo Cijntje and Harry Ford this offseason, it's worth noting that the M's system has undergone a bit of a shuffling this winter.

Let's check in on where things stand with MLB Pipeline's newest edition of the team's Top 30 prospects. It was released on Wednesday morning:

It's worth noting that -- for these purposes -- prospects are players with no more than 130 at-bats, 50 innings pitched or 45 days on a Major League roster, with one major exception. Foreign professionals -- players who are at least 25 and have been professionals in a foreign league for at least six seasons -- do not count, so you will not see offseason signings such as Tatsuya Imai or Kazuma Okamoto in these rankings.

1) Colt Emerson, SS/3B

2) Kade Anderson, LHP

3) Ryan Sloan, RHP

4) Lazaro Montes, OF

5) Michael Arroyo, 2B

6) Jonny Farmelo, OF

7) Felnin Celesten, SS

8) Luke Stevenson, C

9) Nick Becker, SS

10) Yorger Bautisa, OF

1) There's a lot of instant impact here. As stated above, each of the top five prospects could debut this season. The Mariners may prefer to hold off on Anderson and Sloan, but that doesn't mean it can't happen. This team is deep at the major league level, and they have a wave coming to help if necessary.

2) Celesten highly thought of again? After some injuries over the last few years, it seems like the prospect gurus are coming back around on Celesten. Each of the top six M's are in the MLB Pipeline Top 100 (Farmelo No. 78), so Celesten likely isn't off from a return trip into that group.

3) Younger impact too. Just because the Mariners have a top-heavy system right now doesn't mean they don't have younger players building up also. Becker was drafted in 2025 out of the high school ranks and Bautista is a 2025 signing from the international ranks. The duo is 19 and 18, respectively.

--Cijntje ended up ranked No. 5 in the Cardinals Top 30 prospects after the Brendan Donovan trade, while Peete fell all the way to 18.
