Top fantasy baseball prospects: Colt Emerson returns to action, Tyler Bremner impressing in High-A

A quick reminder: This is ONLY players who have Rookie of the Year MLB eligibility, and ONLY a look at potential help for 2026. That out of the way, here’s a look at the top prospects who can help your fantasy roster this season. 1.

Colt Emerson, SS, Seattle Mariners 2026 stats: 21 G, . 250/. 360/.

461, 3 HR, 6 SB, 11 BB, 24 SO at Triple-A Tacoma. Emerson missed a handful of games while dealing with some wrist soreness, but he returned over the weekend. After going hitless in his first contest back, he went 2-for-5 with a homer against Oklahoma City on Saturday, and then doubled and drew a pair of walks during Sunday’s contest.

Brendan Donovan is currently on the injured list with a hip issue, and the team called up Will Wilson to fill the void with Emerson not available. The numbers aren’t overtly impressive, but the talent is, and Emerson should be helping fantasy players before the end of the summer, if not sooner. 2.
