Marta Kostyuk enters this Cincinnati Open round-of-16 clash as the clear favorite, sitting at world No. 11 with a dominant 2026 record of 29-7 and titles already secured in Madrid and Rouen. The Ukrainian’s aggressive baseline game, powerful serve, and heavy groundstrokes have translated effectively on hard courts this season. Sloane Stephens, a veteran qualifier ranked outside the top 250, is still rebuilding match toughness following a 2025 right-foot stress fracture that limited her play; she has posted an 11-14 record in 2026 and recently noted her tennis is functional but not yet at peak level despite a first-round win.
