US Open: Navarro's first Grand Slam semifinal will be against Sabalenka. Fritz and Tiafoe win, too

Emma Navarro's first Grand Slam semifinal will come at the U.S. Open against Aryna Sabalenka. Navarro grabbed the last six games to beat Paula Badosa 6-2, 7-5 in the quarterfinals Tuesday to follow up her upset of defending champion Coco Gauff. There was no such drama in the second-seeded Sabalenka's 6-1, 6-2 victory over Paris Olympics gold medalist Zheng Qinwen at night. That was a rematch of the Australian Open final in January, which Sabalenka won for her second consecutive title there. In the men's quarterfinals Tuesday, Taylor Fritz earned his first berth in the final four at a major by eliminating 2020 U.S. Open runner-up Alexander Zverev in four sets.
