Novak Djokovic had an easy day at the office as he cruised past Juan Pablo Varillas and into a record-breaking 17th French Open quarter-final – against Karen Khachanov.
The 22-time Grand Slam champion was pushed extremely hard by Alejandro Davidovich Fokina in his previous match and struggled physically but there were no such concerns in a 6-3 6-2 6-2 win against Peruvian Varillas.
Djokovic raced into a 4-0 lead and the only time he looked in any discomfort was when Varillas won two games in a row and forced a break point in the next one.
The third seed, who criticised the crowd for booing while he took a medical time-out in his previous match, was again jeered for his reaction and cupped his hand to his ear after winning the next point.
There were plenty of cheers at the end, though, as Djokovic wrapped up the victory after an hour and 57 minutes.
A two-time champion in Paris, Djokovic has now reached the last eight in Paris for a record 17th time, one more than 14-time champion Rafael Nadal who is absent this year due to injury.
