World No.3 Rafael Nadal defeated Italian teenager Jannik Sinner for a third time in as many meetings - all on clay - to reach a record 15th Roland-Garros quarter-final on Monday.

In a rematch of their last-eight clash on Paris' terre battue from last October, Nadal posted a 7-5, 6-3, 6-0 victory over the No.18 seed to extend his Roland-Garros streak to 35 consecutive sets won.

The 35-year-old Nadal needed just two hours and 17 minutes to overcome the talented Sinner, winning 81 per cent of the points behind his first serve, firing 31 winners against 30 unforced errors.

The Mallorcan gets another rematch in the next round as he faces off with Argentina's Diego Schwartzman, whom he beat in last year's Paris semi-finals en route to a record-extending 13th Roland-Garros crown.

Battling Diego

Schwartzman rallied from 1-5 down and saved seven set points in total in his opening set against Jan-Lennard Struff en route to a clutch 7-6(9), 6-4, 7-5 victory over the big-serving German in the fourth round on Monday.

The 10th-seeded Argentinian had been struggling for form in the build-up to Roland-Garros but recaptured his spark on Parisian clay to reach the quarter-finals here for a second straight year and a third time in the last four seasons.

Novak books Berrettini date

World No.1 Novak Djokovic dropped his first two sets of the tournament but advanced to a record 15th Roland-Garros quarter-final when his 19-year-old opponent Lorenzo Musetti retired late in the fifth set with a groin injury.

The Serb lost the opening two sets in tiebreaks before an injured Musetti succumbed 6-7(7), 6-7(2), 6-1, 6-0, 4-0 (ret.).

The 2016 champion will next face Italian ninth seed Matteo Berrettini, who received a walkover into the last eight due to Roger Federer's withdrawal from the tournament.

Third time's a charm for Sakkari

Maria Sakkari had lost on her two previous Grand Slam fourth-round appearances at the US Open and Australian Open last year, but the Greek No.17 seed made sure she was third time lucky on Monday as she advanced to her first major quarter-final with a 6-1, 6-3 upset of 2020 finalist, the No.4 seed, Sofia Kenin.

The 25-year-old Sakkari joins her compatriot Stefanos Tsitsipas in the last eight, making it the first time a Greek woman and a Greek man have both made the quarters at the same major.

"I'm speechless because it's the first time, it's one of my favourite tournaments, I love Paris, I'm having a great time and I don't want to leave anytime soon. I'll try my best to stay until the end for sure," an elated Sakkari told Marion Bartoli in her on-court chat.

"I'm actually enjoying myself, that's the most important thing. I'm enjoying myself on court, I'm actually not torturing myself when I'm on court. The match the day before yesterday gave me a lot of confidence, you saw it, I played really good tennis, so today I was ready for a battle. I just came here, played, and won."

Krejcikova into first major singles quarter-final

World No.33 Barbora Krejcikova put together a ruthless display against 2018 finalist Sloane Stephens to reach her maiden Grand Slam singles quarter-final in Paris on Monday.

The Czech two-time major doubles champion has enjoyed a stunning rise in singles over the past eight months and needed a mere 67 minutes to down Stephens 6-2, 6-0 on Court Suzanne-Lenglen.

Krejcikova saved all three break points she faced and benefited from 26 unforced errors coming off of her American opponent's racquet.

The 25-year-old, who is also into the mixed doubles quarter-finals and women's doubles quarter-finals, is a triple threat in Paris this fortnight and will now face American teenager Coco Gauff.

Coco crushes Jabeur

In a battle of former Roland-Garros junior champions, 17-year-old Gauff made it into the first Grand Slam quarter-final of her career with a 53-minute 6-3, 6-1 rout of No.25 seed Ons Jabeur.

Gauff, who was competing in the fourth round at a major for the third time in her young career, extended her current winning streak to eight victories in a row, having picked up the title in Parma on the eve of the tournament.

The American is an impressive 16-3 on clay this season, with Paula Badosa the only player on tour to have won more matches on the surface in 2021 (17-2).

The 24th-seeded Gauff was ever so composed on court against Jabeur, who couldn't muster a single break point on her opponent's serve and committed 21 unforced errors throughout the contest.

"I'm super happy that I was able to reach my first quarter-final [at a major], I played really well, so I'm happy about that. Thank you guys for coming to watch," said Gauff, who has yet to drop a set this fortnight.

"Parma gave me a lot of confidence, especially on the clay, it was my first title on clay so coming here it gave me a lot of confidence and it taught a lot how to close matches and deal with the pressure on important points."

Australian wheelchair tennis star Dylan Alcott picked up his third consecutive Roland-Garros quad wheelchair singles title with a 6-4, 6-2 success over Dutchman Sam Schroder.
