World No.1 Novak Djokovic has earned a record-breaking 11th consecutive quarter-final appearance at the French Open with a 6-4 6-3 6-3 victory against Russian Karen Khachanov.
Djokovic, who is aiming for a second Roland Garros title since 2016, secured the win in 2 hours 26 minutes under the roof of Court Philippe Chatrier as heavy rain poured down in Paris.
The 17-time grand slam champion will next face 29-year-old Spaniard Pablo Carreno Busta after the No.17 seed set up a rematch against Djokovic by reaching his second quarter-final in the French capital.
Carreno Busta was visited by a doctor after the second set but continued to play well and beat 186th-ranked qualifier Daniel Altmaier 6-2 7-5 6-2.
Just last moth at the US Open, Carreno Busta was gifted progress to the quarters after Djokovic was defaulted for inadvertently hitting a line judge with a ball.
The Serb said he experienced a moment of "deja vu" in the first set against Khachanov when a mistimed return flew off his racket and hit the face of a line judge.
"Obviously because of what happened in New York, people I guess are going to make the story out of this," Djokovic said.
"I saw he had a little bit of a bruise, like redness, in that place in the head where the ball hit him. It was a very awkward situation."
Earlier in the day, Stefanos Tsitipas, seeded fifth, advanced as he battled past Bulgaria's Grigor Dimitrov 6-3 7-6 (11-9) 6-2 in just under two and a half hours.
Tsitsipas bagged a third consecutive victory in straight sets after surviving a five-set scare in the first round.
"It was a very good lesson for me, the first-round match," Tsitsipas said.
"I think I was just more awakened on the court, more responsible for what I was doing. That is also the reason why I've been doing so well in the last nine sets that I've played."
The Greek moves into a quarter-final against 13th seeded Andrey Rublev - a 6-7 (4-7) 7-5 6-4 7-6 (7-3) winner over Hungary's Marton Fucsovics - in a rematch of last week's Hamburg final won by the Russian.
"Both of us had tough, tough week in Hamburg, tough final," said Rublev.
"I hope it's going to be interesting."
