Marta Kostyuk enters the second round of the 2026 WTA Cincinnati Open as the clear favorite against Sofia Kenin on outdoor hard courts, backed by her career-high ranking near No. 11 and dominant 2026 form that includes titles in Madrid and Rouen plus a Roland Garros semifinal. Kostyuk has posted a strong win-loss record this season and carries momentum from recent North American hard-court results. Kenin, ranked well outside the top 100 with a sub-.300 win rate in 2026 singles, faces a steep challenge despite her lone head-to-head victory over Kostyuk in Dubai in 2025. The matchup highlights the gap in current form and consistency, though Kenin’s experience and serve could create opportunities on the fast surface if she capitalizes on any unforced errors from the Ukrainian.
