Qinwen Zheng vs Iga Swiatek

Iga Świątek would likely be the favorite in this matchup, given her superior ranking, experience, and the strength of her overall game. She’s proven to be a mental and physical powerhouse, and her ability to adjust to various surfaces and opponents gives her a major edge. Świątek’s consistency, combined with her ability to change the pace and dominate rallies, would likely prove too much for Qinwen Zheng to handle, especially in longer exchanges.

Qinwen Zheng, while a talented player with plenty of potential, would need to be aggressive and capitalize on any chances to break Świątek's rhythm. Zheng has the power to compete with Świątek from the baseline, but she would have to maintain a high level of consistency and avoid being drawn into long rallies, where Świątek excels.

In summary, Iga Świątek is the clear favorite in this matchup due to her established dominance on the tour, experience in big matches, and mental fortitude. However, Qinwen Zheng could still cause trouble if she plays aggressively and takes risks, though it would take a high-level performance to beat a player of Świątek's caliber.
