Frances Tiafoe delivered one of the week's most gripping performances, rallying from two sets down to defeat fellow American Alex Michelsen 5-7, 3-6, 7-5, 6-3, 7-6 (6) in a nearly five-hour battle at the 2026 US Open (ATP). The comeback saw Tiafoe break back into the top 10 and reach his third US Open semifinal in five years. The pair shared an emotional embrace afterward, with Michelsen visibly distraught after the defeat.

On the women's side, Aryna Sabalenka kept her US Open three-peat hopes alive by edging sixth seed Linda Noskova 7-6 (1), 3-6, 7-6 (10-7) in a third-set tiebreaker thriller. Sabalenka fought through what appeared a title-threatening moment to preserve her world No. 1 position. Noskova faced an unusual disadvantage when she served in shadow after a roof-adjustment delay at a critical juncture. No. 3 seed Jessica Pegula advanced with a 3-6, 6-4, 6-3 rallied win over No. 26 Emma Navarro in an all-American women's quarterfinal. Tiafoe now faces Carlos Alcaraz or Ben Shelton in the semifinals, with the men's and women's draws set to conclude in the coming days.
