Iga Swiatek came through a titanic second-round clash with fellow four-time grand slam champion Naomi Osaka to reach the French Open third round.

Osaka looked set to pull off her biggest win in years when she led the world number one and defending champion 5-2 in the third set.

But the 26-year-old from Japan will have nightmares about a missed forehand as Swiatek survived a match point to come from brink of defeat and win 7-6 (1) 1-6 7-5.

It was a remarkable effort from Osaka, the former world number one who only returned to action after maternity leave in January.

Match report from Andy Sims in Paris

Andy Murray calls on the WTA to “do more to capitalise” on matches such as the one we saw tonight. Interesting comments from the former men’s World No 1. Court Philippe-Chatrier wasn’t full as Swiatek faced Osaka, in the match of the day.

This very much went under the radar as it was on during the Swiatek vs Osaka thriller, but Coco Gauff is safely through to the third round in Paris.

Gauff defeated past Slovenian qualifier Tamara Zidansek 6-3 6-4 and set up a meeting with the winner of a match between China’s Wang Yafan and Ukrainian Dayana Yastremska.

The Queen of Clay fights on. That was a match worthy of the final, not the second round. Huge credit to both.

“For most of the match I didn’t feel here, I was not focused, but when I was under pressure I was actually able to focus more. I didn’t think about losing and I hope my game is going to get better because of that.”

Quite a remarkable interview that from Swiatek, calling out the fans after such a win!

Huge praise for Osaka, too.

“This match was intense, much more intense for the second round than I expected. Naomi played amazing tennis with a loose hand and sometimes risking a lot. She was finding it in and playing great tennis, maybe she will be a clay-court specialist!

“I’m sorry to bring this up because we are playing for you guys, but when we are playing and you scream it is really hard to focus. I usually don’t bring this up because I want to be in the zone, but guys this is serious. It’s hard to accept this. We are playing for big things, big money, guys please if you could support us after the points and not during.

“I hope you guys are still going to like me, because I know the French crowd like to boo!”

That was unprompted by Swiatek. Wow.

Iga Swiatek 7-6 1-6 7-5 Naomi Osaka

Swiatek and Osaka hug at the net, before Osaka quickly leaves the court.

But what a performance from the four-time grand slam champion. SHE IS BACK.

And she could have ended Swiatek’s reign. She had match point ,and the chance to go 5-1 up in the third.

But Swiatek battles on! That was a champion’s comeback.

Now Swiatek is serving for the match – will we get another twist in this remarkable battle?!

It’s so tense – Swiatek and Osaka trade errors in the opening points. Osaka drags two forehands in a row wide!

STUNNING backhand winenr from Swiatek! What an angle! Right on the line!

Now Swiatek has TWO MATCH POINTS!

Osaka goes wide on the backhand and Swiatek, somehow, survives!

I can’t believe how good this is. Swiatek senses a chance and steers a backhand winner to get to 15-30. Osaka responds with an ace. 30-30.

Osaka nets on the forehand – she’s not swinging as freely nwo and it’s BREAK POINT Swiatek.

But Osaka finds the corner with the forehand – I take it now ! – DEUCE.

Another big serve from Osaka gets her to game point but then Swiatek clobbers the next return. Deuce again.

Backhand winner Osaka, beautiful. Drive volley Swiatek! Level again.

A net cord from Swiatek means it sits up for Osaka… but she pushes the backhand long!

BREAK POINT: and Osaka double faults!!!!!! I can’t believe it! Swiatek breaks at last and has come from 4-1 and 5-3 down, match point down, to stand on the brink of the third round!

What a comeback from the champion. But still a great chance for Osaka. I don’t know which way this goes now.
