Taylor Fritz got choked up when it hit him that he had reached the U.S. Open final. Imagine what the 26-year-old Californian’s reaction would be if he actually were to take home the trophy by beating No. 1 Jannik Sinner of Italy on Sunday in Arthur Ashe Stadium. “I have a feeling I’m going to come out and play really well and win,” the 12th-seeded Fritz said Friday night after coming back to get past another American, Frances Tiafoe, in five sets to reach a major final for the first time.
