Roger Federer failed to cope with stifling conditions at the U.S. Open on Sep. 3 and suffered a shock 3-6 7-5 7-6(7) 7-6(3) defeat to unseeded Australian John Millman in the last 16.

Second seed Federer, who had not dropped a set in his first three matches, was uncharacteristically sloppy, committing 77 unforced errors and 10 double faults while landing just 49 percent of his first serves.
