On the monthly update of Baseball America’s top 100 prospect list, the Mariners joined rarified air as an organization with three top ten prospects leaguewide. Colt Emerson (#3), Ryan Sloan (#7), and Kade Anderson (#9) made up the elite trio topping the list, though both Lazaro Montes (#57) and Luke Stevenson (#98) made the cut in this month’s update.
It’s no surprise to see Emerson heading this group after a torrid start to his big league career. Having already produced many memorable moments across
his first handful of games, Emerson has provided a much needed jolt for the Mariner lineup and looks every bit of a long-term mainstay on the infield. He’ll soon graduate from this list, but his final hurrah as a prospect looks on him in an understandably positive light.
Sloan, who jumped rotationmate Kade Anderson this month, has started to settle in at the Double-A level after a month long adjustment period. Recently twirling his best start as a professional, Sloan has built up some tremendous momentum and is being looked upon as the soon-to-be best pitching prospect in baseball. The 20 year old has immense potential and should be a candidate for a big league promotion some time next year.
The aforementioned Anderson has had one of, if not the most dominant starts to the 2026 season in all of minor league baseball. The lefthander has diced up his opposition in all but one inning this year, commanding the zone as well as anyone and striking out the world along the way. He’s been as advertised in his inaugural season.
The final two entrants on the list, Lazaro Montes and Luke Stevenson, carry varying degrees of pedigree. Montes, who’s long graced this list and has been considered one of the premium power prospects for several years now, is not much of a surprise, though Stevenson’s addition comes with slightly more intrigue. After an outlandish start to the season, the young backstop has come back down to Earth a bit, producing a slashline that’s far more human than what he initially laid claim to. Less about his addition to the list and more so about the timing of when they chose to include him, Stevenson is more than deserving of a top 100 nod and looks to be yet another premium prospect the Mariner brass has identified.
