It's already Monday - and June - in Paris, where there promises to be more of the same drama to come on day nine of this fine tournament.

The main event is undoubtedly world number one Aryna Sabalenka against fellow four-time Grand Slam winner Naomi Osaka in a rare women's night session, but we'll be back for live text coverage and BBC Radio 5 Live commentary of men's fourth seed Felix Auger-Aliassime against Chile's Alejandro Tabilo.

Until then, goodnight.

There was yet another surprise result on Court Philippe-Chatrier, with four-time champion Iga Swiateklosing to in-form 15th seed Marta Kostyuk in straight sets.

Men's second seed Alexander Zverev, however, had no such struggles, beating lucky loser Jesper de Jong 7-6 (7-3) 6-4 6-1.

He will face teenager and 27th seed Rafael Jodar in the last eight after the Spaniard came from 2-0 down to beat compatriot Pablo Carreno Busta in five.

Jodar's fellow 19-year-old Joao Fonseca ousted two-time finalist Casper Ruud in four sets while 26th seed Jakub Mensik - only 20 himself - came through a decider to beat 10-time Grand Slam quarter-finalist Andrey Rublev.

Elsewhere, 11th seed Elina Svitolina recovered from losing the opening set to beat Belinda Bencic 4-6 6-4 6-0, veteran 18th seed Sorana Cirstea overcame Xiyu Wang in straight sets as she continues her fairytale final season, and eighth seed Mirra Andreeva won in two.

Joao Fonseca, 19, speaking on court after reaching the French Open quarter-finals for the first time:

"I feel tired - it's a first time for me, it's a new experience for me.

"Getting through to the second week of a Grand Slam is always tough, but it's all heart.

"We try to put heart into it and just focus point by point."

Joao Fonseca is speaking on court after beating Casper Ruud:

"It was tough, Casper plays good here, I mean he is a very experienced guy and he knows how to play here in this amazing court.

"It was tough in the beginning but I played really well in the important moments in the first and second sets, and I was very happy because of that.

"I just try to be me on court - try to be happy, try to hit winners, try to hit good shots and bring entertainment. I try to be me and that's what it is."

I am not sure he knows what to do with himself, the way he has come out in all of these matches. Everyone was wondering how he was going to come out off the back off a five-hour Novak Djokovic match but he came out and he did it again.

This teenager is something special.

Unbelievable stuff.

Joao Fonseca is still rushing the net and it forces Casper Ruud to go for the extremities. He drags his forehand wide.

A cute drop shop at the end of another lengthy exchange brings the error from Ruud.

And then... an ace. Three match points!

How are these guys still going? They're knocking lumps out of each other from the baseline before Joao Fonseca unfurls another forehand winner. 40-15.

Casper Ruud holds to 15.

Joao Fonseca will serve for a spot in the quarter-finals.

That was another big response from Fonseca.

One-two punch. A big serve down the T followed by a crunching down-the-line forehand. Advantage Joao Fonseca.

He closes the hold in playful fashion - a drop shot, a lob (chased very well by Casper Ruud) and a cross-court volley into the open court to seal the deal.

One game away!

Big serve. Huge. 203kph down the T and returned into the net.

Then, Joao Fonseka draws a couple of errors from his Norwegian opponent, a forehand going long and backhand on the slide drifting wide.

But Ruud has gas in the tank and forces deuce.

Joao Fonseca shakes his head as a couple of poor strokes leave him 0-30 down. Is there another twist on Philippe-Chatrier? I'm not sure my keyboard can take it...

Casper Ruud sends a cross-court forehand into the tramlines. His shoulders slump a little more.

Joao Fonseca is two games away from the French Open quarter-finals!

Casper Ruud looks just a little deflated as Joao Fonseca pummels a backhand winner down the line for advantage. Just a little slump of the shoulders.

The points trading continues. Casper Ruud double faults to take the game to deuce.

Joao Fonseca. Stop it.

He's dragged off the court on his forehand, dragged into the opposite corner on his backhand, chases forward for a drop shot and replies with a forehand winner of his own. 15-all.

Back-to-back backhand errors from Joao Fonseca to give up 0-30. He could have been up a double-break a moment ago...

No drama, says Fonseca. He pulls it back to 30-all before hanging in a brutal baseline exchange and being rewarded with the error. He takes a deep breath. That rally was 18 shots long and he was on the backfoot for almost all of it.

Ruud sends a forehand long. Fonseca escapes.

With an ace, Casper Ruud is on the board in the fourth set.
