Emerson, 20, was the first-round pick of the Mariners in 2023 and is expected to make his major league debut in 2026. He's put together a sensational season, hitting .275 across both levels with 12 home runs and 54 RBIs.

He pairs with Michael Arroyo, Jurrangelo Cijntje and Lazaro Montes to make up a star-studded Arkansas roster. It's one of the most talented rosters in minor league baseball, as each of those four are Top 100 prospects.

Emerson is ranked as the No. 14 prospect in the game, per MLB Pipeline.

The following comes from a portion of his MLB.com prospect profile:

Owner of the best hit tool in the Mariners system, Emerson got multiple votes in MLB Pipeline’s annual executive poll as being the best pure hitter in the Minors. He has a smooth and repeatable left-handed swing that enables him to find the barrel and make consistent hard contact. His .419 on-base percentage entering 2025 is a sign of his advanced approach as he’s walked nearly as often as he has struck out thus far in his career, and he rarely chases.

Emerson joined our Refuse to Lose podcast in June, and you can listen to the episode in the podcast player below:
