WORLD number one Novak Djokovic was knocked out of the Shanghai Masters in the quarter-finals by sixth seed Stefanos Tsitsipas.
Greek 21-year-old Tsitsipas came from a set down – having lost the opening three games in seven minutes – to beat the defending champion 3-6 7-5 6-3.
He will play Daniil Medvedev in the semi-finals after the Russian defeated Fabio Fognini 6-3 7-6 (7-4).
Victory confirms Tsitsipas’ debut at next month’s ATP Finals in London.
It also marks the first time Tsitsipas has recorded a win over the current world number one.
Djokovic – who won the Japan Open last week – has never previously failed to make the semi-finals in Shanghai.
He now trails Rafael Nadal by 1,280 points in the battle for year-end world number one.
“He had the high-quality tennis and he played very well after his serve,” the 32-year-old Serb said of world number seven Tsitsipas.
“He was backing up his serve with really good and aggressive first shots in the rally.
“I didn’t make him defend enough. I just gave him enough time to really dictate the play from back of the court and he deserved to win.” – BBC
