Prediction in Beijing semifinal!
Zheng and Mertens both needed three sets in two of their earlier matches at the China Open, and their only previous head-to-head meeting in Charleston in 2025 also went to three sets. Both players have since beaten top-level opponents in straight sets, making this a competitive matchup rather than a guaranteed three-setter.
Match: Zheng vs Mertens
League / Competition: WTA Tour
Our Pick: Over 2,5 sets
Odds: 2.40
Market: Over/Under
Analyst Confidence: 4/5
This China Open semifinal has the potential to develop into a tight battle. Zheng Qinwen won their only previous meeting in three sets at the Charleston Open in 2025, demonstrating how closely matched they can be. Zheng has also won 12 of her last 14 matches, including qualifiers, and has shown resilience in demanding contests.
Mertens arrives in excellent form after defeating Coco Gauff and Iga Swiatek in straight sets. Zheng also impressed with a straight-sets victory over Elina Svitolina. With both players producing strong results against elite opposition, a competitive match with momentum swings is plausible, although both have shown they can win in two sets.
Prediction: Zheng Qinwen to win 2–1🎾✅
