Prospect Spotlight: Colt Emerson, SS, Mariners
Colt Emerson combines elite plate discipline and bat-to-ball skills with projection for power, making him one of the most complete teenage hitters in the minors.
His Bowman Chrome autos — especially Blue /150 and Orange /25 — are already heating up, and a Double-A breakout could push them into elite tier pricing.
Advanced lefty bat with All-Star upside; still unlocking power but already a top-20 prospect driving strong Bowman Chrome hype.
