3-seeded Federer won five consecutive U.S. Open championships from 2004-08 and also was the runner-up twice, including two years ago.

Daniel has never been past the second round at a major tournament. 7 seed Grigor Dimitrov became the latest top-10 man to bow out of the U.S. Open, upset in the second round by 19-year-old Russian Andrey Rublev. 8 Jo-Wilfried Tsonga lost to 18-year-old Canadian Denis Shapovalov in the second round Wednesday night.
