Karen Khachanov vs Ben Shelton

Both players rely heavily on their serving and aggressive play. While Khachanov has more experience and a slightly more polished game, Shelton's raw power and youth could give him the edge in a high-energy match. Shelton’s ability to capitalize on his serve and his explosive forehand might make him a tough opponent for Khachanov.

I’d lean towards Ben Shelton as the favorite, given his potential and explosiveness, especially on hard courts where he can overpower opponents. That said, Khachanov’s experience and solid all-around game could keep it close.
