NEW YORK—For once, a Roger Federer match was not the place to be at a tennis tournament. As Federer and Philipp Kohlschreiber began their fourth-round evening encounter in Ashe Stadium, cheers and roars and chants of “Olé” could be heard coming from the nearby Grandstand, where Juan Martin del Potro and Dominic Thiem had just begun the fifth set of what was fast becoming an epic.
It was hard to imagine a more extreme contrast in scenes. Delpo-Thiem was drawn-out, grueling, suspenseful and operatic; Federer-Kohlschreiber abrupt, businesslike, hit-and-miss and ultimately academic. The Swiss and the German had played 11 times, and the Swiss had won all 11. Make that 12. Federer would go on to win this one, 6-4, 6-2, 7-5, in an hour and 49 minutes.
