Big jumps in Baseball America's top 100 will only fuel Mariners fans' impatience

There were some notable prospect graduations in the first month of the 2026 MLB season, yet that only partly explains why Colt Emerson and Kade Anderson are now top-10 prospects for Baseball America. As Seattle Mariners fans are well aware, both have been forcing the issue.

Given that he checked in at No. 7 in the publication's preseason top 100, that Emerson now ranks at No. 4 isn't news, per se. But the same is not true of Anderson, who has jumped from No. 25 up to No. 9.

Not bad for a guy who's only five starts into his professional career, but have you seen what he's done in those five starts? We're talking 24.1 innings at Double-A with only 13 hits, four walks and one run allowed, all next to 38 strikeouts.

Meanwhile, the Mariners are 18-20 and struggling with production on their infield and consistency in their rotation. Put two and two together, and you can understand why a stroll through Mariners wings of social media reveals a sense that Emerson and Anderson are needed soon, if not now.

The only question is *when* Colt Emerson and Kade Anderson will impact the 2026 Mariners

It's obviously Emerson who has the more straightforward timeline. He's only 20 years old, but he has 153 Triple-A plate appearances under his belt and the elevator pitch for his promotion is ultimately simple.

For one, he's already signed a $95 million contract extension. For two, even his iffy offensive profile doesn't obscure how much of an upgrade he'd be in the field. The Mariners seem to have accepted that he belongs at shortstop and not at third base, as he's taken 26 of his 29 starts for Tacoma at the former.

Generally, Emerson's major league ETA is definitely "2026." And whether the exact moment comes via necessity or via desperation, the smart money is on it happening soon.

As for Anderson, recent promotions of Paul Skenes and Chase Burns allow for some optimism in terms of thinking sooner over later. Both were in the big leagues within a year of getting drafted, which speaks to a broader pattern of faster-moving prospects.

Still, let's hold off on pushing Anderson until he shows his dominant act at Double-A translates to Triple-A. If it does, that's when you can imagine the Mariners playing the Skenes/Burns card and deciding Anderson is done with the minors. Skenes made only seven starts at Triple-A. Burns made only two.

For the meantime, it's fair game to imagine how Anderson will eventually fit into the starting rotation. It's five deep now and will be six deep when Bryce Miller returns, but that feels tenuous. Only George Kirby and Emerson Hancock have been consistent, so pieces are bound to get moved through some combination of an injured list stint, a bullpen demotion and maybe even a trade.

No matter how it works out, that Emerson and Anderson are still waiting to enter the picture feeds into the belief that the grass must eventually get greener for this Mariners team. It's been rough going so far, but the best simply must be still to come.
