Re: 2026 Prospects Thread
Keith Law just came out with his Top 100 list for The Athletic.
He has Colt Emerson at #4, which is higher than both Baseball America (7) and MLB Pipeline (9).
Here is the writeup:
The Mariners’ first pick in the 2023 draft, Emerson is already on the brink of making the big leagues, even though he won’t turn 21 until July. After an injury-shortened 2024 season, Emerson got a full year’s work — exactly 600 PA — while playing at three levels in 2025, hitting .285/.383/.458 overall and making excellent swing decisions until he spent the final week in Triple A, where he was the second-youngest player after Nelson Rada. He has quick hands and generates plus bat speed, combining it with very advanced pitch recognition for his age, as he doesn’t chase much at all (22 percent in High A, where he spent most of the year) and picks up pitch types well already. He started the year putting the ball on the ground too often and appears to have dropped his hands just a little by year-end, with much lower ground-ball rates in Double A and Triple A, although he might want to drop them a little further to at least cement those gains in his line-drive rates. He’s kept the possibility of playing shortstop in the big leagues alive due to his hard work, as he’s a 45 runner and doesn’t have the naturally quick actions you want in a shortstop, and is more likely to end up at another position, probably third base. He really, really looks like he’s going to hit, both in the sense of making contact and hitting the ball hard enough to matter, and will do so while playing some position of value on the dirt. If he ends up at 20-plus homer power, which is probably his ceiling, he’s a superstar. Maybe he’ll hit .300-plus with enough secondary value in walks, doubles and defense to be a superstar even without a gaudy home run total. I’m not betting against him given how fast he’s moved and how hard he works.

Re: 2026 Prospects Thread
Next up is Ryan Sloan.
Keith Law ranking: 21
Baseball America: 60
MLB Pipeline: 33
Keith's ranking here squares more closely with my own evaluation that he's the highest upside prospect the Mariners' system right now, and possibly the best pitching prospect we've had since Felix.
Here's the writeup:
Sloan has all of the ingredients you’d want in a No. 1 starter: He’s big, he fills up the zone, he’s got three pitches that might all be plus, and while it’s not a necessity for the job, he does have a giant fastball that hits triple digits. The Mariners’ second pick in 2024, Sloan went to Low A to start his pro career and wasn’t just dominant — he was efficiently dominant, peaking at five innings per start and never needing more than 72 pitches in any outing. His sweeper is his best pitch right now; when he finishes it out front, it breaks sharply downward with a little tilt, and hitters whiffed on the pitch 46 percent of the time they swung. He also throws a kick-change — who doesn’t — that dies just enough as it approaches the plate to get hitters to swing right over it, although he has to keep throwing it to improve his feel for the pitch. His arm action is a little bit long in back, not enough to keep him from repeating it or throwing strikes, which he did all year with a 4.5 percent walk rate. The Mariners bumped him up to High A in August, and he was hit around a little bit, as he looked tired and wasn’t finishing as well over his front side. If I have any concerns about Sloan, it’s just that he is so good, so soon. He turns 20 on Jan. 29 and is already showing velocity that would put him among the hardest-throwing starters in the majors. Protect him at all costs — he looks like an ace in the making.

Re: 2026 Prospects Thread
And then we have Kade Anderson.
Keith Law Ranking: 28
Baseball America: 25
MLB Pipeline: 21
Here's the writeup:
The No. 3 pick in the 2025 draft, Anderson was dominant at LSU last spring, working with five pitches (counting his fastballs separately), showing excellent feel already for the zone and for mixing all of his weapons to get left- and right-handed hitters out. He’s 91-95 and it plays up thanks to a plus changeup that has hitters off-balance, while his slider is his best breaking pitch and I think the Mariners should probably deprecate the curveball, at least for now, to focus on developing the slider. He really repeats his delivery and holds his mechanics very deep into starts — occasionally too deep, as he threw 130-plus pitches twice in his draft year. Even as is, he has at least average command already of a major-league arsenal, maybe without the wipeout pitch to make him a front-line starter just yet, and could pitch in the Mariners’ rotation this year if they need him. There’s at least No. 2 upside here beyond that as he’ll probably pick up some velocity and should tighten the slider with more focus on the pitch.

Re: 2026 Prospects Thread
Michael Arroyo
Keith Law Ranking: 49
Baseball America: Unranked
MLB Pipeline: 67
Here's the writeup:
Arroyo signed back in January 2022 for $1.375 million, which feels like forever ago, but he just turned 21 in November and has already reached Double A, showing superlative contact skills and an outstanding eye at the plate. His carrying tool is the bat, as he hit .269/.422/.512 in High A and .255/.376/.341 in Double A, actually cutting his strikeout rate at the higher level down to a career-low 15.6 percent. He’s got a very simple, direct swing that’s geared towards low line drives, with line-drive rates in his career consistently in the 20-27 percent range, including 25.6 percent in that stint in Double A. He loves the ball middle-down, with some weakness on fastballs towards the top of the zone, and he has very strong ball/strike recognition overall. He’s an average to above-average second baseman, with some throwing issues early in 2025, and played a couple of games in left field in the Colombian Winter League to try to add some versatility given the Mariners’ surfeit of infielders. His bat will make him a regular anywhere, while his chances to be an above-average regular are probably tied to him playing second base for somebody.
