Vienna Open: Novak Djokovic suffers shock defeat in quarter-finals


The Serb was beaten 6-2 6-1 by the world number 42, who only came into the tournament as a lucky loser.

Sonego will face Dan Evans in the semi-finals after the Briton outlasted Bulgarian Grigor Dimitrov.

Evans showed plenty of determination to come through 7-6 (7-3) 4-6 6-2 in two hours and 42 minutes.

It is the second week in a row that the world number 33 has reached the semi-finals, after Antwerp last week, where he lost to Ugo Humbert.

"It feels great," Evans said afterwards. "I'm happy to come through a difficult match."

Earlier, Djokovic looked out of sorts in the opening set of his match as his 25-year-old Italian opponent took control.

He kept up the intensity in the second set, a double break putting him 4-1 up, and held his nerve for a famous win.

Sonego lost to Aljaz Bedene in the final round of qualifying but earned a spot in the main tournament after the withdrawal of Diego Schwartzman.

He is yet to drop a set on his way to the semi-finals.

"It's the best victory of my life. Novak is the best in the world," he said.

"Today I played so, so good. It's unbelievable. It's amazing."

It is the first time Djokovic has ever been beaten by a lucky loser.

It also means he will have to wait a little longer before he completes the formality of equalling Pete Sampras' all-time record of ending the season top of the rankings for a sixth time.

The other semi-final will feature South African Kevin Anderson against fifth-seeded Russian Andrey Rublev.

Anderson beat Russian fourth seed Daniil Medvedev 6-4 7-6 (7-5) while Rubev defeated out-of-form second seed Dominic Thiem 7-6 (7-5) 6-2.
