Swiatek tucks in to double bagel - in just 40 minutes

Novak Djokovic will have been as envious as sin.

For while the men's champion didn't get to bed until dawn after his 3.07am defeat of Lorenzo Musetti at the French Open, his female counterpart Iga Swiatek then breezed into Court Philippe Chatrier at a perfectly civilised hour on Sunday and tucked into an early lunch of 'double bagel' against Anastasia Potapova.

Swiatek made the 6-0 6-0 demolition against the unfortunate Russian look preposterously easy, taking just 40 minutes to complete the job and book what promises to be a rather more challenging quarter-final date with Wimbledon champ Marketa Vondrousova, who beat Serbian qualifier Olga Danilovic 6-4 6-2.

Swiatek lost just 10 points in the shortest match of her professional career, hitting 13 winners and making just two unforced errors in a display of rare efficiency.

Gauff waves
Coco Gauff also made light work of qualifying for the quarter-finals.

And she was certainly happier to be doing her day job than having to endure the frankly ridiculous 10.30pm start that Djokovic had to put up with.

Asked about why she had asked not to play night sessions, she explained simply: "There's no issue - I just like to sleep normally.

"I was always one of the players that said that we should start a little bit earlier. Also, I don't know if the fans are watching these matches if they have to go to work next day or something when the matches are finishing at 2:00 or 3:00 a.m."

It was hard not to feel sorry for Potapova, though. She revealed that the long days of hanging around and not being able to prepare during incessant rain delays had contributed to her getting ill and then being whitewashed.

"Yesterday I spent all day on site because I had doubles. We came at nine in the morning and at 7pm it got postponed. I spent all day here without hitting a ball," said the Russian.

"That's not the preparation for the fourth round of a grand slam against the world No.1."

There followed another impressive outing on Chatrier from world No.3 Coco Gauff, who breezed past Italian Elisabetta Cocciaretto 6-1 6-2 on a day when, mercifully, the roof could be opened with no fear of the reappearance of the rain which had plagued the previous five days.

Ons Jabeur, who will be Gauff's quarter-final opponent, continued her quest to win that elusive maiden grand slam after losing in three finals with a 6-4 6-4 win over Denmark's Clara Tauson, who had already knocked out former slam champs in Jelena Ostapenko and Sofia Kenin.

And the last word on what the answer to these late, late-night finishes might be was left to the ever-smiling Tunisian 'Minister for Happiness'.

It was simple, she explained with a smile. "If it had been woman's match, it would have been finished early..."
