The young guns continue to shine at the U.S. Open, as women's No. 1 Iga Swiatek, men's No. 3 Carlos Alcaraz, and men's No. 22 Frances Tiafoe reach the quarter finals. Swiatek has an incredible eight titles and 37 consecutive wins coming into this tournament, but the noise of New York City - and the Open's raucous crowd - could throw her off her game. For Tiafoe, it's the chance to achieve a lifelong dream that started on the courts of a Maryland tennis center, where his father, an immigrant from Sierra Leone, worked on the maintenance staff. He's got a chance to become the first American man to win the Open trophy in almost 20 years, but can he make it past Rafael Nadal?
