US Open glance: Federer, Djokovic can set up quarterfinal

NEW YORK (AP) — A quick look at the U.S. Open:

LOOKAHEAD TO MONDAY

Roger Federer and Novak Djokovic have only a pair of unseeded opponents between themselves and a highly anticipated quarterfinal showdown at Flushing Meadows. Federer, the No. 2 seed, faces 55th-ranked John Millman; Djokovic, the No. 6 seed, takes on 68th-ranked Joao Sousa. Neither Millman nor Sousa ever has reached the final eight at any Grand Slam tournament. “He’s got an aura about him. Definitely a player I’ve looked up to throughout my career. But it’s like anything. I have never been a fan of playing anyone’s reputation. When you go out on court, I think it’s about engaging in a battle. I definitely won’t be thinking about those things if I play against him,” Millman said about facing Federer, with whom he practiced ahead of the grass-court portion of this season. “I want to start off at zero-all and not already being behind the 8-ball and playing someone’s reputation. If you do that, I think you can get bogged down and you’re in a bit of trouble.” Those two matches will be in Arthur Ashe Stadium, as will 2006 champion Maria Sharapova vs. No. 30 Carla Suarez Navarro, and 2017 runner-up Madison Keys vs. No. 29 Dominika Cibulkova.
