Cincinnati, OH, United States (4E Sports) – John Isner ousted world No. 1 Novak Djokovic, 7-6(5), 3-6, 7-5, in the quarterfinal of the Western & Southern Open, spoiling the top seed’s chance to complete a Career Golden Masters by sweeping all nine Masters 1000 events.
Isner matched Djokovic with nine aces with no double faults and saved three of four break points to beat the Serbian in two hours and 23 minutes.
Djokovic had five double faults, including a crucial one in the third set that helped Isner escape with the victory.
Djokovic was attempting to become the first player in history to sweep all nine Masters 1000 events by winning the Cincinnati event.
For a spot in the final, Isner will meet Juan Martin del Potro, who advanced to the semifinal after beating Dmitry Tursunov, 6-4, 3-6, 6-1.
Del Potro fired 15 aces and won 81 percent of his first serve points to finish off Tursunov in under two hours.
“I served well. I made many aces. I’m looking forward to tomorrow,” del Potro said.
Meanwhile, Tomas Berdych advanced to the semifinal after a 6-3, 6-4 victory over Andy Murray.
Berdych’s four Masters 1000 semifinal in 2013 is a career-high for the sixth-ranked Czech, having advanced as far in Indian Wells, Madrid and Rome. It is his second semi-final in Cincinnati as well.
Berdych will face the winner of the Roger Federer-Rafael Nadal showdown, which will be played in the evening.
On the women’s side, top seed Serena Williams beat Simona Halep, 6-0, 6-4, to advance to the semifinal against Li Na, who advanced via walkover when Agnieszka Radwanska pulled out of the event to attend her grandfather’s funeral.
Jelena Jankovic reached the semifinal for the third time after defeating 12th seed Roberta Vinci, 6-0, 6-4. She awaits the winner between second seed Victoria Azarenka and 10th seed Caroline Wozniacki.
