World No.1 Novak Djokovic produced a majestic display in a 7-5, 6-3 victory over American John Isner on Thursday.
Those breaks came in a commanding period. At 5-5 in the opening set, the 16-time Grand Slam champion swung the momentum of the match his way by winning five games in a row. “It’s always a big challenge returning the serve of Isner,” Djokovic said of his 6-foot-10-inch opponent.
“He’s got one of the biggest serves. I managed to read it and find a good position on the return at the end of the first set and also at the beginning of the second. It was one of the best-serving matches I had lately.”
Defending champion Djokovic will next play sixth seed Stefanos Tsitsipas of Greece, who beat Poland’s Hubert Hurkacz 7-5, 3-6, 7-6(5) in the only three-setter of the day. Twice champion Roger Federer was far from his best, but did enough to overcome David Goffin 7-6(7), 6-4. Federer committed 40 unforced errors, but saved five set points in the opening set.
The second seed will be up against German Alexander Zverev, who dispatched Andrey Rublev 6-0, 7-6(4) in 84 minutes. Third seed Daniil Medvedev also advanced with a 7-6(7), 7-5 victory over Canadian Vasek Pospisil, while fourth seed Dominic Thiem recorded a straightforward 6-3, 6-4 win over Georgian Nikoloz Basilashvili.
