Australian Open 2023 LIVE: Jessica Pegula vs Victoria Azarenka latest score and Stefanos Tsitsipas in action

Follow live updates from the Australian Open as the quarter-finals begin in Melbourne. An unpredictable opening week of the first grand slam of the season has seen the top two seeds of the men’s and women’s draws tumble before the last-eight stage, and there is now an opportunity for those who remain. Among them, third seeds Stefanos Tsitsipas and Jessica Pegula have the chance to win a first grand slam title and both are in action in the primetime slot on Rod Laver Arena.

Pegula is the firm favourite to win her first grand slam title with Iga Swiatek now out in the women’s draw, and the American continues her campaign against Victoria Azarenka. The two-time Australian Open champion is bidding to reach her first semi-final at Melbourne Park since she won her last title in 2012. The winner will face Elena Rybakina in the semi-finals after the Wimbledon champion defeated Jelena Ostapenko 6-2 6-4 in a one-sided contest.

Tsitsipas survived a five-set battle with Jannik Sinner in the fourth round and now faces the rising star Jiri Lehecka in the last eight. After not winning a match at a grand slam in four previous attempts before this week, the young Czech has knocked out Felix Auger-Aliassime and Cameron Norrie so far and is targeting a third scalp against Tsitsipas - who is aiming to reach his third consecutive Australian Open semi-final. Earlier, Karen Khachanov reached the semi-finals after Sebastian Korda retired injured while trailing 7-6(5) 6-3 3-0.

Australian Open 2023: Stefanos Tsitsipas 6-3 7-6 6-4 Jiri Lehecka - Game, set and match!

12:41 , Jamie Braidwood

Tsitsipas: “It felt different this time to any other match but the most important thing in the end was I found a solution. It was a very difficult three-setter. Jiri had a really good tournament, he’s a great player. I had to deal with the groundstrokes that were coming over much heavier, much deeper. The tiebreak was a crucial moment. That was my opportunity to take a massive lead and I was very happy with how I closed out the second set.”

Asked how he got out of 0-40 in the third set, Tsitsipas says: “Experience”.

Australian Open 2023: Stefanos Tsitsipas 6-3 7-6 6-4 Jiri Lehecka - Game, set and match!

12:36 , Jamie Braidwood

Tsitsipas, like he did in the tiebreak, senses his chance to strike. On 30-30 he whips a brilliant backhand winner passed Lehecka, setting up match point.

And that’s it! Lehecka had done admirably to hang on throughout the second and third sets, but he nets on the backhand with Tsitsipas pushing for the win.

Tsitsipas stays perfect in grand slam quarter-finals and advances to his third consecutive Australian Open semi-final, where he will play Karen Khachanov.

12:29 , Jamie Braidwood

It looked to be crumbling for Lehecka after he threw in a double fault to face 0-30, but just like Tsitsipas in the last game he manages to climb back to hold. That was a big response after missing out on three break points.

Tsitsipas rattles out a hold to love.

Australian Open 2023: Stefanos Tsitsipas 6-3 7-6 4-3 Jiri Lehecka*

12:23 , Jamie Braidwood

Oh, hello. Tsitsipas throws in a double fault and suddenly Lehecka has three break points at 0-40. His concentration has just slipped a touch and Lehecka finds himself with a huge chance.

Lehecka misses on the second serve - maybe that was his chance - Tsitsipas puts away the forehand winner, and then the Greek serves an ace down the middle!

What a brilliant hold - as Tsitsipas clips the line with a forehand winner, Lehecka sees a further three break point chances slip away. He’s 0/8 now.

12:17 , Jamie Braidwood

Is another tiebreak fast approaching? Neither player is getting a look on the other player’s serve whatsoever. Lehecka continues to serve very well.

Australian Open 2023: *Stefanos Tsitsipas 6-3 7-6 2-2 Jiri Lehecka

12:12 , Jamie Braidwood

Even though Tsitsipas increased his levels dramatically in the second set tiebreak, it has been very level between the two players since the opening exchances of the first. They have traded blows game by game and Lehecka continues to look comfortable on this stage, as he shows off his latest impressive drop volley at the net.

Australian Open 2023: *Stefanos Tsitsipas 6-3 7-6 1-1 Jiri Lehecka

12:04 , Jamie Braidwood

It’s a long way back for Lehecka now - but the Czech plays a lovely drop volley on 30-30 on serve to get an opening hold.

Australian Open 2023: Stefanos Tsitsipas 6-3 7-6 Jiri Lehecka - Tsitsipas wins the second set

11:54 , Jamie Braidwood

Another first serve from Tsitsipas. The winner follows. 6-1 and five set points.

Tsitsipas with the crosscourt forehand winner! He takes the second set on the tiebreak.

The Greek just decided there to increase his level and Lehecka couldn’t live with it.

Lehecka missed a big opportunity when he had five break points in the third game.

Australian Open 2023: Stefanos Tsitsipas 6-3 6-6 Jiri Lehecka - Tiebreak!

11:50 , Jamie Braidwood

Tsitsipas is rock solid on the opening point and draws the error from the 21-year-old, who goes long against serve. 1-0

And then Tsitsipas increases the power, unloading on a huge forehand winner to take charge of the rally. 2-0

Ace! Sensational start from Tsitsipas. 3-0

Tsitsipas again with power and depth - Lehecka thought he had adjusted by it’s been taken up a level. Tsitsipas puts away the smash. 4-0.

Lehecka pulls one back but Tsitsipas finds the first serve out wide to take a big lead into the changeover. 5-1

11:46 , Jamie Braidwood

Tsitsipas returns the favour, holding with little trouble.

Onto a tiebreak we go.

Australian Open 2023: *Stefanos Tsitsipas 6-3 5-6 Jiri Lehecka

11:44 , Jamie Braidwood

A rapid hold from Lehecka - sealed by an ace - and it earns the 21-year-old a tiebreak at least.

Australian Open 2023: Stefanos Tsitsipas 6-3 5-5 Jiri Lehecka*

11:42 , Jamie Braidwood

Tsitsipas faced a pressure point at 30-30 after his backhand broke down and crashed into the net, but replies with a big ace out wide. It’s followed by a big fist pump and he gets the hold.

Pressure back on Lehecka.

Australian Open 2023: *Stefanos Tsitsipas 6-3 4-5 Jiri Lehecka

11:37 , Jamie Braidwood

Lehecka moves to 40-0 with an accurate serve out wide followed by a forehand winner down the line. He has done well to hold on to his serve and get to five games, where Tsitsipas will be under pressure now serving to stay in it.

Australian Open 2023: *Stefanos Tsitsipas 6-3 3-4 Jiri Lehecka

11:29 , Jamie Braidwood

Lehecka moves inside the baseline and puts away the one-two punch off that big forehand, which is really starting to warm up.

Australian Open 2023: Stefanos Tsitsipas 6-3 3-3 Jiri Lehecka*

11:22 , Jamie Braidwood

That’s an impressive response from Lehecka as he holds. He’s in this second set, that’s for sure.

It’s followed by a swift hold from Tsitsipas - a reminder of how rare a chance those five break points could turn out to be.

Australian Open 2023: Stefanos Tsitsipas 6-3 2-2 Jiri Lehecka*

11:19 , Jamie Braidwood

Tsitsipas roars as he gets his hold - after saving five break points. Lehecka is working out how to play this match but can he react to failing to take those chances?

Australian Open 2023: Stefanos Tsitsipas 6-3 1-2 Jiri Lehecka*

11:14 , Jamie Braidwood

For the second game in a row, Lehecka gets a look at 15-30 on the Tsitsipas serve after the Greek nets on the backhand - this time Lehecka takes control of the rally after going big towards the Tsitsipas backhand, before flashing a winner that just clips the line.

Two break points: Tsitsipas fires a 200kmh ace down the middle on the first, and then Lehecka goes wild on the return on the second.

But the Lehecka forehand to the Tsitsipas backhand is working well and he claws himself to a third break point chance, finished off with a smash this time.

Netcord! But it drops on Lehecka’s side from the forehand! Another attack to the Tsitsipas backhand brings a fourth break point.

On the second serve, Tsitsipas kicks and rushes the net, forcing Lehecka into the miss on the return. It’s followed by a forehand winner from Lehecka, another chance - but saved again by the Tsitsipas serve!

Australian Open 2023: Stefanos Tsitsipas 6-3 1-1 Jiri Lehecka*

11:02 , Jamie Braidwood

Lehecka gets a nice boost with a return winner off the Tsitsipas serve, and then the Greek pushes wide from midcourt in a poor forehand error.

So, a first look for the 21-year-old Czech: Tsitsipas thunders a first serve, and then whips the forehand winner. Lehecka developed the rally on 30-30, but Tsitsipas wins the exchange of backhands.

And Tsitsipas moves in well on the Lehecka backhand before clipping a lovely volley. Solid hold from 15-30.

Australian Open 2023: Stefanos Tsitsipas 6-3 Jiri Lehecka* - Tsitsipas wins the first set

10:54 , Jamie Braidwood

Tsitsipas wraps up the first set behind some huge serving. Lehecka barely got past 15 on the Tsitsipas serve and the Greek won 84 percent of his first serves. That was very comfortable after striking to take the early break.

Australian Open 2023: *Stefanos Tsitsipas 5-3 Jiri Lehecka

10:52 , Jamie Braidwood

Tsitsipas beats Lehecka down on the duel of forehand crosscourt shots and the Czech nets twice in a row to face 30-30. But with Tsitsipas two points away Lehecka tightens, and at least asks the question to the Greek to serve this out.

Australian Open 2023: Stefanos Tsitsipas 5-2 Jiri Lehecka*

10:49 , Jamie Braidwood

Lehecka is finding himself pinned so far behind the baseline and Tsitsipas is covering the net well. Lehecka is struggling to find a foothold against serve so far.

Australian Open 2023: *Stefanos Tsitsipas 4-2 Jiri Lehecka

10:45 , Jamie Braidwood

Lehecka lets Tsitsipas have a first taste of his explosive forehand and takes charge of the rally from there - he finishes a hold to love with a brilliant drop shot. There are some encouraging signs for the 21-year-old but it’s a different story on the Tsitsipas serve.

Australian Open 2023: Stefanos Tsitsipas 4-1 Jiri Lehecka*

10:40 , Jamie Braidwood

Lehecka has yet to react to the power of the Tsitsipas serve so far, as the Greek charges in a for a serve and volley to close out another comfortable hold.

Australian Open 2023: *Stefanos Tsitsipas 3-1 Jiri Lehecka

10:37 , Jamie Braidwood

That should help Lehecka settle some of those early nerves. The Czech plays a lovely drop volley at the net and is able to hold to 15 from there.

Australian Open 2023: Stefanos Tsitsipas 3-0 Jiri Lehecka*

10:33 , Jamie Braidwood

Big serving from Tsitsipas puts the pressure straight on Lehecka once again.

Australian Open 2023: *Stefanos Tsitsipas 2-0 Jiri Lehecka - Tsitsipas breaks

10:32 , Jamie Braidwood

Lehecka is given an early taste of the power Tsitsipas can generate when he loosens his wrist and is faced with 0-30 early. Lehecka is bold to get the first point back and then Tsitsipas makes the error on the second serve.

But the Czech is still trying to adjust when the ball is in play and Tsitsipas is able to force five break point opportunities. Lehecka saves the first four impressively but can’t get out of trouble in what is a nervy start.

Tsitsipas finally gets the breakthrough with a tricky lob, as Lehecka misses on the ambitious overhead.

Australian Open 2023: Stefanos Tsitsipas 1-0 Jiri Lehecka*

10:21 , Jamie Braidwood

Tsitsipas moves into a strong position but Lehecka plays a lovely forehand lob after reaching a volley from Tsitsipas. It’s followed by Tsitsipas hitting the net with a forehand slice, and suddenly it’s deuce.

There’s a big serve from Tsitsipas and Lehecka fires wide on the forehand.

Australian Open 2023: Stefanos Tsitsipas vs Jiri Lehecka

10:17 , Jamie Braidwood

Here we go! Tsitsipas will serve first, under the roof on Rod Laver Arena. The winner will face Karen Khachanov in the semi-finals.

Lehecka is playing in his first grand slam quarter-final, Tsitsipas his sixth. The Greek has won all five previous quarter-finals at the majors.

Australian Open 2023: Stefanos Tsitsipas vs Jiri Lehecka

10:15 , Jamie Braidwood

Stefanos Tsitsipas on the pressure of being the highest seed remaining in the men’s draw: “I play my game. Titles come if I play good. That takes care of itself, I think. If you’re able to play the best you can produce on the court, I feel like the rest just follows naturally.

“It’s a natural flow of things. Putting pressure on yourself... We’re all dealing with pressure when we’re playing. For us, we are out there on a different race every single time, a race with different conditions, a race with a different player by our side. That’s I think something that most players are focused at.”

Australian Open 2023: Stefanos Tsitsipas vs Jiri Lehecka

10:09 , Jamie Braidwood

There’s a quick turnaround for our next match, which will see Stefanos Tsitsipas take on the rising star Jiri Lehecka. It should be a great atmosphere as Tsitsipas is heavily supported in Melbourne.

Australian Open 2023: Jessica Pegula 4-6 1-6 Victoria Azarenka - Game, set and match!

10:00 , Jamie Braidwood

Azarenka: “Honestly, it was very scary for me physically to fail. I was afraid to fail, that I wouldn’t be able to finish certain things. It hurts my ego.

"Last year my tennis wasn't bad, but I mentally wasn't there. I played with a lot of fear, a lot of anxiety. It really was difficult to be brave and to make the right choices... I worked a lot on my mindset, challenging myself, trying to push myself forward."

Australian Open 2023: Jessica Pegula 4-6 1-6 Victoria Azarenka - Game, set and match!

09:59 , Jamie Braidwood

Azarenka: "It hurts to beat her, because I always want her to do well, but at the same time I I knew I have to play my best tennis. She’s been playing amazing and I knew from the first point that I had to bring it. I had to stay there, take opportunities. I'm very proud that I executed my game plan really well. It's amazing to be in the semi-final of another grand slam."

Australian Open 2023: Jessica Pegula 4-6 1-6 Victoria Azarenka - Game, set and match!

09:53 , Jamie Braidwood

Yep, Pegula is completely beaten here. It’s going to be a fifth defeat in a row in the quarter-finals of a grand slam, but the third seed is not the story here.

What a performance that was from Victoria Azarenka! The two-time champion rolls back the years to dump out the tournament favourite. Her approach and strategy was spot-on.

Australian Open 2023: Jessica Pegula 4-6 1-5 Victoria Azarenka*

09:50 , Jamie Braidwood

Pegula slumps a weary forehand into the net and looks in disbelief at her strings. It looks like that previous hold from Azarenka was a fatal blow to that belief, too, and Azarenka jumps on it to take the fourth consecutive break of the American’s serve. The semi-final is now in reach.

Australian Open 2023: *Jessica Pegula 4-6 1-4 Victoria Azarenka

09:45 , Jamie Braidwood

Pegula, desperately looking for answers, tries to chip a drop-shot but gets it horribly wrong. Azarenka meets it easily and puts away winner down the line and it leads to the hold.

Australian Open 2023: Jessica Pegula 4-6 1-3 Victoria Azarenka* - Azarenka breaks!

09:42 , Jamie Braidwood

Pegula’s serve is having very little effect so far, as Azarenka sets the tone of the rallies from the returns. She forces the third consecutive break of serve to start the second set, as Pegula continues to struggle.

Australian Open 2023: *Jessica Pegula 4-6 1-2 Victoria Azarenka - Pegula breaks!

09:36 , Jamie Braidwood

The advantage is returned straight back to Pegula as Azarenka hits long on the backhand - there has been a slight drop in level from both players to start this second set.

Australian Open 2023: Jessica Pegula 4-6 0-2 Victoria Azarenka* - Azarenka breaks!

09:31 , Jamie Braidwood

Azarenka keeps her foot down and works the opening hold, in a repeat of the first set. Pegula again looks exasperated at the work she is having to do to create opportunities from the baseline, as Azarenka continues with her determined approach.

Australian Open 2023: Jessica Pegula 4-6 Victoria Azarenka* - Azarenka wins the opening set!

09:23 , Jamie Braidwood

And suddenly the momentum swings again! Pegula drops a set for the first time this tournament as Azarenka gets ahead. I think she had learned from the four set points she had missed and went more aggressive on the Pegula serve. Azarenka reestablished control of the rallies and put the pressure on Pegula. It was the story of the first set, but there are enough signs there that Pegula can hit back in the second set.

Australian Open 2023: *Jessica Pegula 4-5 Victoria Azarenka - Pegula breaks!

09:16 , Jamie Braidwood

Two more set points quickly come Azarenka’s way - after she fires a brilliant forehand winner down the line and Pegula concedes a cheap point by going long.

Pegula responds well in a rare example of her power taking over, leading to the forehand winner - and the American saves the second too by stepping into the baseline and powering a driven forehand past Azarenka.

This is much better from Pegula and Azarenka then throws in a double fault! Brilliant again from Pegula - that’s three rallies in a row that she’s taken charge of - and as Azarenka clips the netcord the American takes the break!

Back level.

Australian Open 2023: Jessica Pegula 3-5 Victoria Azarenka*

09:09 , Jamie Braidwood

Pegula has yet to drop a set all tournament and errors from the American leads to set two points at 15-40. Azarenka misfires on three consecutive returns and Pegula is able to get out of it as Azarenka again goes long.

Pegula, for now, fights on in this opening set but Azarenka will serve for it next.

Australian Open 2023: *Jessica Pegula 2-5 Victoria Azarenka

09:02 , Jamie Braidwood

Pegula is starting to look agitated as he motions to her box. “I don’t know what to do,” she saus. “The ball is not going anywhere!”

Azarenka moves to 40-15 but Pegula then snaps at a forehand winner down the line, and when Azarenka goes long on the backhand it gets her to deuce.

Azarenka produces a brilliant forehand winner stepping inside the baseline and seems to be set for the hold, but Pegula mixes it up with a lovely backhand return.

Azarenka nets and another error brings up Pegula’s first break point. Azarenka saves it well and from there, sticks to her game to take an important hold.

Australian Open 2023: Jessica Pegula 2-4 Victoria Azarenka*

08:54 , Jamie Braidwood

Azarenka moves in well to pick up a volley at the net but Pegula, moving better now and starting to crate some angles, takes the hold.

Australian Open 2023: *Jessica Pegula 1-4 Victoria Azarenka

08:48 , Jamie Braidwood

Suddenly Azarenka is not having it all her own way. She hits long on the backhand under no pressure as Pegula gets to deuce on the 33-year-old’s serve. Pegula is trying desperately to create some angles, but Azarenka steers a stunning backhand crosscourt. Pegula looks to attack the second serve but nets.

Australian Open 2023: Jessica Pegula 1-3 Victoria Azarenka*

08:44 , Jamie Braidwood

And Pegula does, at last, get the hold. After saving six break points that could be a big moment in this opening set.

Australian Open 2023: *Jessica Pegula 0-3 Victoria Azarenka

08:39 , Jamie Braidwood

This is sublime from Azarenka. She arrows a crosscourt forehand winner into the corner to move to 15-40 on the Pegula serve and bring up two points for a double break. Pegula saves them with two good first serves but she continues to confound Pegula from the baseline rallies to set up another.

Pegula moves in on the backhand slice from Azarenka to save the third, and has to do so again on the fourth to save with a flying forehand winner.

This is a long game but you can tell Pegula is starting to build some confidence, despite the slew of break point opportunities Azarenka is getting.

Australian Open 2023: *Jessica Pegula 0-3 Victoria Azarenka

08:29 , Jamie Braidwood

This has been a brilliant start from Azarenka, who is taking charge of the rallies and asking Pegula to to hit for the lines from uncomfortable positions. Very impressive so far from the 33-year-old.

Australian Open 2023: Jessica Pegula 0-2 Victoria Azarenka*

08:24 , Jamie Braidwood

Azarenka has put Pegula on the backfoot to start this match. The American pulls out a sublime backhand pass on the run but Azarenka puts the pressure on at 30-30. Pegula steers wide and Azarenka continues to attack with deep balls to the baseline to force the opening break.

Australian Open 2023: *Jessica Pegula 0-1 Victoria Azarenka

08:21 , Jamie Braidwood

Azarenka makes a solid start on serve, backing up good power to the Pegula backhand by moving into the net. Pegula was able to hit back when Azarenka left it short, and the American got back to 30-30, but Azarenka takes the hold as Pegula pushes a lob long and then nets on the defence.

Australian Open 2023: Jessica Pegula vs Victoria Azarenka

08:18 , Jamie Braidwood

There have been four previous meetings between Jessica Pegula and Victoria Azarenka and the head-to-head is split at two wins each. Pegula won the last meeting in straight sets in the semi-finals of the Guadalajara Open, but the American has lost all four of her previous grand slam quarter-final appearances.

Azarenka is much more experienced at this stage of the grand slams and the 33-year-old is looking to reach her first Australian Open semi-final since she won her last title in Melbourne in 2012.

Australian Open 2023: Jessica Pegula vs Victoria Azarenka

08:08 , Jamie Braidwood

Here we go, Azarenka and Pegula, who are two great friends, make their way out onto the court on the Rod Laver Arena as the night session gets underway. Azarenka is wearing her Paris Saint-Germain shirt, which has become a regular sight this week.

Australian Open 2023: Jessica Pegula vs Victoria Azarenka

08:00 , Jamie Braidwood

Victoria Azarenka on trying to make new memories at the Australian Open: “I made history here. For me, my name is always going to be there on the wall. It’s definitely historic for me. But I don’t really look back and think about what I have done. I just try to really create new memories. I’m not the person who looks back, either regrets or is happy about the past.”

On facing the in-form Jessica Pegula: “She’s amazing player. Her stability and consistency throughout I wouldn’t only say last year, I would say the years before that. She’s been an incredible player. She got me here, so I definitely want revenge. She’s a great friend of mine. I absolutely adore her. We have really tough battles every single time. We practice with each other. There’s going to be no surprises absolutely. It’s going to be tough, it’s going to be a lot of rallies, the ball is going to be low.”

Australian Open 2023: Jessica Pegula vs Victoria Azarenka

07:52 , Jamie Braidwood

Jessica Pegula on being the highest seed left and the opportunity to reach her first grand slam semi-final: “It’s an interesting feeling, I guess. I still don’t really feel like that. I mean, I look at the draw and there’s still girls, today she won French Open, you have Rybakina who won Wimbledon last year, you have Vika who does really well here. It doesn’t really feel like I’m the highest left, even though I guess that’s a cool stat. It feels like there’s still a long ways to go, to be honest.

“I definitely want to obviously reach a semi. It will be my first semi. I mean, I have a great shot here. I think I’m playing probably my, all around throughout the whole tournament, I’ve been playing the best I have than in any of my other grand slam quarterfinals. That I think helps.”

Australian Open 2023: Elena Rybakina reacts to reaching Australian Open semi-finals

07:39 , Jamie Braidwood

Elena Rybakina, reacting to her win over Jelena Ostapenko: “I think of course I got all the experience at Wimbledon, and it’s helping me now this time here in Australia and I know what to expect. For sure it’s just easier in this case after Wimbledon. Feeling good on the court and just really enjoying every match I’m playing here.

On her form since winning Wimbledon: “I had tough period before Wimbledon in the sense I was very tired mentally. I played a lot of tournaments, so I was not at my best and I took a break. So it was kind of not really expected win at Wimbledon. But here it’s different because, first of all, I already did it once, and of course I got confident that I can do it again. I did really good preparation with the team. I’m not really surprised with the results. I’m happy. I’m just hungry to work and improve more.”

On her possible semi-final opponent: “They are tough opponents for me. We know each other well. Was a tough match against Jessica in Guadalajara, but there it was also special conditions. And against Vika in Indian Wells. Yeah, tough opponents, but like always, I will try to prepare, I will try to watch the matches, analyse, think about this, and for sure I’m gonna give my best on the court.”

Australian Open 2023: Karen Khachanov into semi-final as Sebastian Korda retires

07:29 , Jamie Braidwood

Sebastian Korda retired with a wrist injury during his Australian Open clash with Karen Khachanov, sending the Russian through to a second consecutive grand slam semi-final.

American Korda has been one of the stories of the tournament, defeating Daniil Medvedev and Hubert Hurkacz to reach a first slam quarter-final 25 years after his father Petr lifted the trophy.

But he began to struggle half way through the second set, receiving a medical time-out, and, after losing seven games in a row, called it quits trailing 7-6 (5) 6-3 3-0.

It was a very disappointing way to bow out for the 22-year-old, who was in obvious discomfort and was reduced to chopping forehands in a vain attempt to find a way back into the match.

Having reached the last four at a slam for the first time in his 23rd major tournament at the US Open last summer, Khachanov is now back at the same stage in his next event.

Australian Open 2023: Wimbledon champion Elena Rybakina sails through to semi-finals

07:26 , Jamie Braidwood

Wimbledon champion Elena Rybakina became the first player into the Australian Open semi-finals after outmuscling Jelena Ostapenko 6-2 6-4 in a one-sided contest on Rod Laver Arena.

The Russian-born Kazakh looked sharp from the start and only a 25-minute delay to close the stadium roof against a passing shower prevented her from wrapping up the opening set within a half-an-hour of arriving on court.

Former French Open champion Ostapenko looked unable to cope with Rybakina's pace and power in the opening stanza but ramped up her own fierce groundstrokes to break for a 2-0 lead at the start of the second.

Rybakina, who ousted top seed Iga Swiatek in the fourth round, broke straight back, however, and saved four break points with some brilliant tennis in the next game to consolidate.

The 23-year-old rode the momentum to break her Latvian opponent again for a 3-2 lead and then it was only a matter of looking after her impressive serve.

Follow live updates from the Australian Open as the quarter-finals begin in Melbourne. An unpredictable opening week of the first grand slam of the season has seen the top two seeds of the men’s and women’s draws tumble before the last-eight stage, and there is now an opportunity for those who remain. Among them, third seeds Stefanos Tsitsipas and Jessica Pegula have the chance to win a first grand slam title and both are in action in the primetime slot on Rod Laver Arena.
