World number one Novak Djokovic suffered a shock defeat by Italy's Lorenzo Sonego in the quarter-finals of the Vienna Open.
The Serb was beaten 6-2 6-1 by the world number 42, who only came into the tournament as a lucky loser.
Djokovic looked out of sorts in the opening set as Sonego took control.
The Italian kept up the intensity in the second set, a double break putting him 4-1 up, and he held his nerve for a famous win.
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.
