World number one Novak Djokovic made it to the French Open quarter-finals for a record-extending 11th successive year after he defeated Russian Karen Khachanov in what was his biggest test yet in the tournament.
The 33-year-old Serb faced a tough opponent in Khachanov, who pushed him throughout the match, but he came out on top with some quality display to win 6-4 6-3 6-3.
Next for Djokovic is Spanish 17th seed Pablo Carreno Busta.
Stefanos Tsitsipas got to his first quarter-final with a 6-3 7-6 (11-9) 6-2 victory over Bulgarian Grigor Dimitrov.
The Greek fifth seed will play 13th seed Andrey Rublev after the Russian defeated Marton Fucsovics 6-7 (4-7) 7-5 6-4 7-6 (7-3).
That quarter-final is a rematch of last month’s Hamburg final, where Rublev won Tsitsipas in three sets.
Carreno Busta, who defeated German qualifier Daniel Altmaier 6-2 7-5 6-2, was Djokovic’s opponent when he was disqualified from this year’s US Open for hitting a line judge with a ball in frustration.
