Gauff 1-6 0-0 Svitolina*
In short, a nightmare first set for Coco Gauff.
Gauff's fourth double fault brings Elina Svitolina to 30-30 and the 12th seed continues to make her pay. A booming forehand takes her to break point.
With the first set all but done and dusted, Gauff produces one more double fault to bring an end to a 29-minute opener.

Svitolina has been more of a passive tennis player and I think she is forcing herself to be aggressive and brave when she needs to be in the back end of her tennis career.
When you look at players who have won slams, it's those who really go after it - those take control of titles and they play to win. They don't play for their opponents to miss.
*Gauff 1-5 Svitolina
A stunning forehand down the line from Elina Svitolina completes a fightback from 0-30 to hold serve for a commanding 5-1 lead in the first set.
Undoubtedly a confidence boost for Coco Gauff to land a couple of winners there as she attempts to reset.
Gauff 1-4 Svitolina*
Coco Gauff responds to Elina Svitolina's opening ace with her first winner of the match.
And another on the backhand!
The third seed appears to be finding some rhythm here, but Svitolina recovers to 30-30 with a big first serve.

But the American drops a forehand into the net and loses serve to love. A really tough start for Gauff is only getting tougher at the moment.
*Gauff 1-3 Svitolina
Elina Svitolina whacks a forehand wide as Coco Gauff's pressure pays off for 15-30, but the third seed looks up with an arm raised in frustration as she nets a backhand to give Svitolina game point.
Relief for Svitolina! A first hold of serve in this contest, clinched with a forehand winner, puts her in control of the opening set.
Gauff 1-2 Svitolina*
It doesn't feel like we're going to have a shortage of break point opportunities in this one, I think it's safe to say.
Elina Svitolina has two more on Coco Gauff's serve... and it's a disappointing second double fault in the space of three points for the American as she concedes again.
*Gauff 1-1 Svitolina

That was a gruelling rally of 26 shots. It was really physical, using the full court there.
Those rallies are mental, mini-battles, If you come out second best it never feels great. Mentally, you weren't able to wear down your opponent.

The crowd show their appreciation at the end of a 26-shot exchange, as Elina Svitolina nets on her next game point.
This game extends into a ninth minute as Coco Gauff is denied a first break point, but she'll get her second!
All level at one game apiece and the early signs suggest this could be a marathon.
Gauff 0-1 Svitolina*
Elina Svitolina hits long following a 12-shot rally which has both players shuffling side to side along the baseline, giving Coco Gauff hope of an immediate response at 15-30.
The Ukrainian gets to game point but undercooks a forehand for deuce. Tricky start for both players on serve.
Gauff 0-1 Svitolina*
Elina Svitolina makes the early breakthrough as Coco Gauff misses a backhand. The perfect start for the 12th seed!
*Gauff 0-0 Svitolina
It's Coco Gauff to serve first in this women's quarter-final.
The American appears to have taken positive steps with her serve, so often a problem area for her in the early stages of her career.
A powerful first serve down the centre wins an important fourth point to level at 30-30 - but a double fault gives Elina Svitolina break point.
Gauff v Svitolina
Image source, ReutersCoco Gauff is the youngest player to reach three consecutive Australian Open quarter-finals since Maria Sharapova made four in a row between 2005 and 2008.
Elina Svitolina is through to her a 14th major quarter-final but is aiming to reach her first Australian Open semi-final after three losses at this stage in Melbourne.
Warm-ups complete. It's show time on Rod Laver Arena...
Gauff v Svitolina
Image source, Getty ImagesCoco Gauff has never reached the final in Melbourne.
The 21-year-old French Open champion, seeking to reach her second Australian Open semi-final, attributes her current run - and, in particular, improvement in her serving - to "trusting herself".
She wrote "confidence is the key" on a camera lens after her fourth-round win.
"My history has been tough with the serve but I think today was great, there was one loose serve in the second set but after that it was pretty good," she said.
"That's the biggest thing, just trusting myself and knowing that I've put in the work in practice and knowing it will show up in the matches.

Svitolina beat a 16-year-old Gauff in straight sets in Melbourne in 2021 but the American has won their two most recent meetings, coming from behind to win in three sets at the Auckland Open and US Open in 2024.
Gauff has already produced one comeback win in this year's Australian Open, dropping a set against Hailey Baptiste before going on to win 12 of the next 15 games.
Image source, Getty ImagesIt is the first time in the Open era that the top six seeds in both the women's and men's singles have reached the quarter-finals at a Grand Slam event.
There remains the possibility that the semi-finals of both competitions feature all four top seeds.
The last time the top four women's seeds reached the semi-finals at a Grand Slam was at Wimbledon in 2009. That hasn't happened at the Australian Open for 33 years.
It is only the fifth time in the Open era that the top six seeds in the men's draw have all reached the quarter-finals at a Grand Slam.
The last time the top four men's seeds all progressed to the semi-finals at a major was at the 2019 French Open, when Novak Djokovic, Rafael Nadal, Roger Federer and Dominic Thiem were left standing.

Two-time Grand Slam champion Gauff is playing in a third consecutive quarter-final in Melbourne, having bowed out at this stage in 2025 and reached the semi-finals in 2024.
Svitolina has lost each of her previous three Australian Open quarter-finals and hasn't reached the last four at a major since 2023 (Wimbledon).
However, the 31-year-old is on a nine-match winning streak in 2026, dropping just one set (in the Auckland Open quarter-finals).
