US Open glance: Quarterfinals to be set after Labor Day play

A quick look at the U.S. Open :

LOOKAHEAD TO MONDAY

The remainder of the men’s and women’s quarterfinals will be set. Rafael Nadal and Roger Federer play their fourth-round matches, and another former champion is in action in a match where he considers himself the underdog: No. 24 Juan Martin del Potro, who won the 2009 title when he beat Nadal and Federer back-to-back, faces No. 6 seed Dominic Thiem. “He’s having a great season already. He’s the favorite for the match. But I like to play him,” del Potro said. Federer will play the winner of that match if he can beat No. 33 Philipp Kohlschreiber, while the top-seeded Nadal goes against unseeded Alexandr Dolgopolov. On the women’s side, top-seeded Karolina Pliskova and No. 4 Elina Svitolina both face American opponents. Pliskova opens play in Arthur Ashe Stadium against unseeded Jennifer Brady, while Svitolina takes on No. 15 Madison Keys in a night match.
