It’s time for today’s night session. We’ve got the reigning champion, Iga Swiatek up against 18-year-old Marta Kostyuk. The Ukrainian is ranked at 81 in the world. The players are due on Chatrier from 20:00 BST.

GAME, SET AND MATCH! – SWIATEK 6-3 6-4 KOSTYUK. The 2020 champion’s title defence continues as she comes through a tricky encounter against another rising starlet to set up a last eight showdown with No.17 seed from Greece, Maria Sakkari. Swiatek hit back from 0-30 to claim it on a second match point with an improvised backhand volley lob.

Not many saw that coming given how tired and irritated she was looking a few moments ago.

BREAK! - SWIATEK 6-3 2-1 KOSTYUK. Has her frustration and the fatigue of the battle finally got to Kostyuk? She chokes up a break to love with an untimely double fault. The Polish No8 seed is on the charge.

SWIATEK 6-3 1-1 KOSTYUK. That’s a thumping hold to love. The Swiatek forehand finds some rhythm and the drive volley isn’t too shabby either. Both on the board early doors in Set 2.

SWIATEK 6-3 1-0 KOSTYUK. There’s a squeal of horror as she misses what can only be described as a sitter but Marta battles on and lures another error out of Swiatek’s usually trusty forehand on her way to a plucky hold.

SET! - SWIATEK 6-3 KOSTYUK. The reigning champion continues her Nadal-esque run of sets won in Paris as she serves out a tight opener on her third set point in 48 minutes. Kostyuk more than played her part but couldn’t push on with an early wing of momentum her way.

BREAK! – SWIATEK 5-3 KOSTYUK. There’s the breakthrough. Some testing angle on a couple of backhands lure the error on an attempt down the line from Marta and Swiatek seizes the moment. She will now serve for a far from straight-forward set. It’s been hugely competitive.

SWIATEK 4-3 KOSTYUK. That is top class from the world number 81 but she fades at the wrong time in the game and Iga wriggles out of danger. The 18-year-old shows real speed and tremendous hands to pick up Swiatek’s drop shot and angle a beauty of a winner back across court. It tees up double break point but she blows a big chance on the second one when she fizzes a forehand long. Iga stays solid from deuce and stays on course.

SWIATEK 3-3 KOSTYUK. It feels like every time she wins a point Marta needs to scream a ‘come on!’ She bellows it on more than a couple of occasions here as another gruelling game goes her way from deuce. No sign of Swiatek running away with this one.

SWIATEK 3-2 KOSTYUK. This is a highly intriguing tussle. Both players are mixing some outrageous winners with poor decision-making and errors in high-octane rallies.

BREAK! – SWIATEK 2-2 KOSTYUK. Iga taps on the door, then she batters away on it but Kostyuk is defiant in her superb defensive work and fends off four break points with some seriously clutch tennis.

There was a contentious moment leading up to the fifth chance as Kostyuk played a shot despite thinking it would be called out. It wasn’t and she’s a tad unfortunate there.
