It's been a costly pattern so far for Ilya Ivanska - and it has continued in the third.

The Belarusian loses his serve early in the third set - at the first time of asking - and now has the tennis equivalent of an Alpine mountain climb on his hands.

A guttural roar of approval from Ons Jabeur - she has tamed Iga Swiatek.

No better way to finish than an ace - ninth of the match telling its own story.

Just terrific - what a match to watch.

Three match points for Ons Jabeur.

Jabeur's showing us the full range, with a brilliant two-handed backhand down the line, that sets up break point, which she takes.

Ons Jabeur, the 21st seed and world number 24, on the verge of dumping out the seventh seed here.

A brilliant two-handed cross-court forehand from Jabeur deserved to find the line and, after a Hawk Eye review, it did, just. Deuce.

A through-the-legs tweener from Swiatek only hits the bottom of the net and she then loses her balance as well. But she's fine to carry on.

Elena Rybakina has been absolutely furious with the chair umpire after an ace was taken away from her to have the point replayed.

She then saves a break point with a backhand down the line.

We're still on serve in this deciding set.

A scream and a fist pump from Ons Jabeur, who has to fight hard to save two break points but it's a very, very important hold and seventh seed Iga Swiatek is in loads of trouble. She's 4-1 and a break down in the decider.

Ons Jabeur was at 30-0 and then had a point for 4-1, but Swiatek has a break point.

An unreturnable serve wipes it out though.

Jabeur had won five out of five break points before now, and that is now six out of six. A double fault from Swiatek, her fifth of the match, comes at a disastrous time.

Swiatek has to produce the splits to keep one point alive, and shows incredible athleticism to do so, but can then only send a forehand long with her very next shot and that's 0-30 on the Swiatek serve. Chance for Jabeur to get a break here.

You think when Jabeur is hitting the ball harder, is more dominant - does she believe she can take this?

You can't keep a top seed down for too long, though.

Berrettini earns a couple of break points as he sets about the Ivashka serve, only for the world number 79 to get himself off the hook both times with some smart plays.

A deft lob from the Italian, followed by a fierce forehand down the line when it returns, sets up a third chance... ace from the Belarusian.

This is gruelling to even watch. Belarusian backhand into the net tees up numero cuatro - and this time Berrettini gets it!

British pair Harriet Dart and Heather Watson have lost the second set of their third round doubles match against Taiwan's Hao-Ching Chan and Latisha Chan.

After Dart and Watson edged the first set, Chan and Chan responded with a double break in the second on court 14.

A rapid-fire hold to love from Jabeur and we're on serve in the third.

Two comfortable service games to get us going in the third set. Jabeur sends a forehand three-quarters up the net and that gives Swiatek a hold to 15.

Russian 25th seed Karen Khachanov has levelled things up against American Sebastian Korda as they battle for a quarter-final spot on court 18.

In another closely-contested set, Khachanov took his second set point on the Korda serve to break the world number 50.

First set Swiatek, second set Jabeur, which way will the decider go?

It's a hold to love from Jabeur for an emphatic start to the third.
