Clay court king Rafael Nadal has overcome a wobbly start to subdue Italian teenager Jannik Sinner 7-5 6-3 6-0 and book a place in the French Open quarter-finals.
Looking to claim a record-extending 14th Roland Garros singles title and become the only man with 21 Grand Slam singles crowns, the Spaniard has won 35 consecutive sets in Paris.
At 19, world No. 19 Sinner has been labelled as the next big thing in tennis, but hit a brick wall on court Philippe Chatrier, after leading 5-3 in the opening set.
Third seed Nadal will now face Argentine Diego Schwartzman for a place in the semi-finals.
Schwartzman recovered from a slow start to defeat Jan-Lennard Struff 7-6(9) 6-4 7-5 and reach the quarter-finals for a second straight year.
World No. 1 Novak Djokovic has survived a huge scare, as he fought back from two sets down against teenager Lorenzo Musetti, after his Italian opponent retired with cramps in the fifth set.
Top seed Djokovic was outplayed by an inspired Musetti, as he lost two tiebreaks, but the match then changed dramatically, as the Serb fought back to 6-7(7) 6-7(2) 6-1 6-0 4-0, before progressing to the last eight in Paris for the 15th time.
He will play another Italian, after Matteo Berrettini was handed a walkover, after Roger Federer's withdrawal.
World No. 76 Musetti's stylish game threatened to send Djokovic to his earliest Roland Garros exit since 2009.
But after producing tennis of the highest calibre in two sensational sets, Musetti blew up, as the effort he had expended to eclipse Djokovic caught up with him.
The 19-year-old lost the third set in 24 minutes and did not even get a point in set four until the fifth game, as the match slipped away from him.
"It's not an injury," he explains. "It's just a little bit of cramps and a little bit of low back pain.
"There was no chance that I could win a point, so I decided to retire, because I think it was the best thing."
