Iga Swiatek and Jessica Pegula are set to face off in the US Open women's quarterfinals, while Jannik Sinner will compete against Daniil Medvedev for a spot in the men's semifinals. Swiatek expressed satisfaction with her performance and noted her strong head-to-head record against Pegula, who is eager to bring her best tennis into the later rounds. Sinner, who recently defeated Tommy Paul, acknowledged the physical and mental challenges ahead against Medvedev, who has a slight edge in their past matchups. The tournament has seen significant upsets, with defending champion Novak Djokovic and last year's winner Carlos Alcaraz both eliminated early. Sinner's form has been strong, and he seeks to capitalize on the absence of his top rivals. The excitement builds as the competition narrows down, promising higher-quality matches leading to the finals.
