U.S. Open quarters would be a pretty good time to get him." In their most recent meeting, Djokovic beat Fritz last month in the quarter-finals of a U.S. Open tune-up event in Cincinnati that the Serbian went on to win by beating Carlos Alcaraz. Should Fritz prevail over Djokovic it would set up an all-American semi-final against the winner of the late match at Arthur Ashe Stadium between 10th seed Frances Tiafoe and unseeded Ben Shelton. The day's other women's quarter-final sees Czech 10th seed and French Open finalist Karolina Muchova facing Romanian 30th seed Sorana Cirstea.
