A quick look at the U.S. Open :
LOOKAHEAD TO THURSDAY
No surprise here: Roger Federer and Rafael Nadal are both going to be back in Arthur Ashe Stadium for their second-round matches, just as they were for their openers. Federer, owner of 19 Grand Slam titles, is on the afternoon schedule, taking on Mikhail Youzhny of Russia, one match after needing five sets to edge 19-year-old American Frances Tiafoe. Nadal, who has won 15 major trophies, faces Daniel Taro of Japan at night. Federer and Nadal could wind up facing each other in the semifinals next week. Two American men get opportunities to make a statement by knocking off past Grand Slam semifinalist: Taylor Fritz plays No. 6 Dominic Thiem of Australia, who has reached the final four at the French Open twice; Donald Young goes up against No. 18 Gael Monfils, the only 2016 U.S. Open semifinalist in this year's field at Flushing Meadows. In the women's draw, Nicole Gibbs of the U.S. takes on No. 1-seeded Karolina Pliskova of the Czech Republic, the runner-up in New York a year ago.
