Ash Barty defeated Danielle Collins in an enthralling final to cap a supreme Australian Open campaign with a maiden title in her home grand slam.

Barty was made to work hard for her success by unlikely finalist Collins and had to come from 5-1 down in the second set to prevail 6-3 7-6 (7-2) on Rod Laver Arena.

It was to the delight of a partisan Melbourne crowd, who saw an Australian triumph in a singles event at the season's first major for the first time since Chris O'Neil in 1978.

Barty, who has now won 11 matches in a row in 2022, clinched her third grand slam title at the first opportunity, a sublime cross-court forehand sealing a sensational triumph.

Barty had offered the first sign of nerves and had to save the match's first break point with a brilliant forehand winner before recovering to hold.

Yet she turned the tables in the next game, Collins tensing up and conceding the first break when she sent two serves long.

With the crowd behind her, Barty got into her groove, holding with ease before two fantastic forehands paved the way for her to serve out the set.

Barty seemed primed to take the match away from Collins in the second set, yet the top seed was stunned as she slumped to a 3-0 deficit.

Having conceded serve for just the second time in the tournament, Barty squandered two immediate chances to break back, Collins coming out on top in a thrilling rally.

There were more fist pumps from Collins as she held to go 4-1 up. A brilliant passing shot gave Barty hope in the next game, but she rushed a volley and followed with a double fault to hand her opponent two break points.

Collins took the first to put herself on the brink of restoring parity, only for Barty to rally back with a break of her own and start a quite sensational comeback.

Having held for 6-3, Barty appeared to have left herself too much to do when she went 30-0 down on Collins' next serve but reeled off four straight points to send the crowd into raptures before levelling the set with a fine hold.

Collins needed to regain her composure and did so to reach the tie-break, but a foreland long put Barty in control, and the crowd were on their feet after a volleyed winner made it 4-0.

Collins struck the net and then missed the court to grand Barty four championship points, and the comeback was complete with her slick forehand.

DATA SLAM: Barty's home run

The first Australian woman since 1980 to reach the final of this major, Barty became the first woman to win a grand slam title in her home country since Sloane Stephens triumphed at the 2017 US Open.

She is also the first woman ranked world number one to lift the trophy since Serena Williams in 2015, ending a run of top-ranked players losing the Australian Open final, after Simona Halep in 2018 and Serena Williams in 2016.

Ash Barty ended the host nation's 44-year wait for an Australian Open singles champion after beating Danielle Collins in straight sets on Saturday.

Ash Barty's form at the Australian Open gives her deserved favourite status for the final, but in Danielle Collins one of the most dangerous players on the WTA Tour stands between her and history.

Barty has ruthlessly cruised into Saturday's final – the first Australian to reach the women's singles decider in 42 years – in brilliant form.

The two-time grand slam champion has lost just 21 games on her way to the showpiece, dropping serve just once.

Barty, the world number one, has appeared a class above at the year's first grand slam, where she is bidding to become the first Australian singles champion since Chris O'Neil in 1978. But she faces a huge test in the final against American 27th seed Collins, who is into her first major decider.

After three straight losses to Barty, two of which were on clay, Collins beat the Australian in straight sets in Adelaide last year in a sign of what she is capable of. Collins, who came from a break down in both sets in that win, possesses the power to threaten Barty on Rod Laver Arena.

Barty's variety – her serve, backhand slice and ability to construct points – has been much talked about in Melbourne this year.

Her 35 aces for the tournament are the second most, and exactly half of her first serves have been unreturned at the event, the highest percentage of any player in the women's draw. While Barty will try to unsettle Collins with her variety, the American is likely to respond with power. Collins has crushed 32 return winners at the event, a tally that is eight more than the next best.

Collins has also delivered 164 winners to 149 unforced errors, showcasing her aggressiveness, while Barty is at 106 and 96 respectively.

If Barty can extend the points, she will fancy her chances of a first Australian Open title. Collins has spent 10 hours, 37 minutes on court compared to Barty's 6:06, but shorter points would also suit the 2019 Australian Open semi-finalist.

Of points between zero and eight shots this tournament, Collins has won 458 of 809 (56.6 per cent), while Barty is 331-202 (62.1). But of rallies of nine-plus shots, Collins is 23-31 compared to Barty's 30-19 at the 2022 event.

Barty will be well aware of what Collins is capable of, but should have confidence her best is more than good enough to end Australia's long wait.

Australia expects as Ash Barty faces Danielle Collins in Saturday's grand slam final at Melbourne Park.

The world number one, from Ipswich, Queensland, will be bidding for her third grand slam singles title but a first at the Australian Open.

The wait for a home champion has been a long one, but it could soon be over.

Chris O'Neil was the last Australian winner of the women's singles, way back in 1978, while the last men's singles champion was Mark Edmondson in 1976.

Australia has hardly been starved of tennis talent over the past 40 years, but for one reason or another, the home slam has been beyond their reach.

Here, Stats Perform remembers the household names who have seen their hopes dashed in Melbourne.

Jelena Dokic

Dokic never came close in Melbourne, truth be told. Which is not to say she lacked the ability, having reached the Wimbledon semi-finals in 2000 and climbed as high as number four in the WTA rankings two years later. Dokic's career was blighted by a traumatic relationship with her overbearing and violent coach and father, Damir, whom she alleged physically abused her on many occasions. Her best performance at Melbourne Park came against all expectations, at the outset of a tour comeback in 2009 when she reached the quarter-finals, losing out there to Dinara Safina. Dokic, who is now 38 and retired from the tour, has been conducting on-court interviews during this year's Australian Open.

Lleyton Hewitt

'Rusty' won Wimbledon and US Open titles at the peak of his powers, and reached number one in the world at the age of 20. Before Roger Federer came along with different ideas, it seemed Hewitt might rule the roost in the men's game for years to come. He reached one Australian Open final, and in 2005 that was a glorious chance to secure a home major as he faced Russian Marat Safin in the final. Hewitt won the first set, but then Safin took command, winning in four. Incredibly, it would be the last grand slam men's singles final not to feature Federer, Rafael Nadal or Novak Djokovic until the 2014 US Open (Nishikori v Cilic).

Pat Cash

Cash's career peak came at Wimbledon in 1987, when he beat Ivan Lendl to capture the title before famously climbing up to the players' box. At the start of that year he almost won the Australian Open, too, when that tournament was staged on grass at Kooyong, in Melbourne's suburbs. He lost a five-set thriller to Stefan Edberg, another grass-court master, and when the tournament moved to Melbourne Park a year later, shifting to hardcourts, Cash was a finalist once more. Again, he suffered heartbreak in a deciding set, Mats Wilander denying Cash home glory, and he would never play a grand slam final again.

Samantha Stosur

Stosur, who called time on her singles career after a second-round defeat in Melbourne this year, was Australia's most recent women's singles grand slam champion until Barty came along. She triumphed at the 2011 US Open, sensationally beating Serena Williams in the Flushing Meadows final, and got to as high as number four in the world. She also reached the 2010 French Open final, but Stosur was never a factor in the business end of her home major, at least in singles. The fourth round was the furthest she ever went, but it was a different story in doubles, as she won an Australian Open mixed title in 2005, alongside fellow Australian Scott Draper. In the twilight of her career, in 2019, she teamed up with Zhang Shuai to win the women's doubles, a poignant success after so much singles frustration.

Mark Philippoussis

Philippoussis, aka 'Scud', was a US Open runner-up in 1998 and also reached the 2003 Wimbledon final, where he was the sacrificial lamb as Federer scooped the first grand slam title of his career. In Australia, though, just like Stosur, his slam peak was round four, a disappointment considering his talent and weaponry. In 1996, Philippoussis stunned the then world number one Pete Sampras in the third round in Melbourne, only to lose to lowly ranked compatriot and doubles expert Mark Woodforde in his next match. Arguably the most famous story concerning Philippoussis and the Australian Open is the widely reported rumour he was spotted kissing Anna Kournikova in an underground car park at the 2000 tournament. Both denied it. "Just good friends," was Kournikova's verdict.

Pat Rafter

Rafter won back-to-back US Opens in 1997 and 1998, as well as reaching consecutive Wimbledon finals in 2000 and 2001. A semi-final run in Melbourne in 2001, which proved to be the serve-volley master's last year on tour, was Rafter's best performance at his home slam, eventual champion Andre Agassi coming from two sets to one down to deny him a place in the title match.

Nick Kyrgios

All the talent in the world, but Kyrgios appears to be happy enough ploughing a unique furrow though his tennis career. Top five in the shot-making stakes, Kyrgios turns 27 in April and his ability has taken him to just two slam quarter-finals to date, including at the 2015 Australian Open. He was a junior champion at Melbourne Park in 2013, and has also reached the fourth round twice in the seniors. It is up to Kyrgios whether he wishes to make optimum use of his remarkable racket skills or carry on entertaining with virtuoso, but short-lived, singles runs. You wonder whether a Barty triumph could ignite this firecracker of a player.

Ash Barty will plot a path to victory over Danielle Collins in the Australian Open final with the coach she describes as "a magician" and "a massive part of my life".

Australian home hero Barty has been a hot favourite for the title since before the first ball was struck in Melbourne, and to date she has justified all the hype and expectation.

Barty has dropped only 21 games across six matches to reach the final. Since 2000, only Serena Williams (16 games at the 2013 US Open and 19 at the 2012 US Open) and Venus Williams (20 games at Wimbledon in 2009) have lost fewer games to reach a grand slam final.

The last player to lose fewer games en route to the final in Australia was Monica Seles in 1993 (20 games), and she went on to beat Steffi Graf in a title match that went to three sets.

This is the level Barty is at now, as an established world number one and reigning Wimbledon champion, and a Collins victory on Saturday would be a major upset.

Yet Barty sees the 28-year-old American as a major threat, and the evidence of Collins' destructive performance against seventh seed Iga Swiatek in Thursday's second semi-final attests to that.

Collins won 6-4 6-1 and hit 27 winners and only 13 unforced errors, securing a place in her first slam final.

"She's an exceptional ball striker," said Barty. "She's someone who stands on the baseline and can hit all spots of the court from any position. I think the challenge is going to be trying to get her off balance.

"We'll do our homework and try to figure out a plan, and come Saturday try and execute. Danielle's done incredibly well here in Australia before. The way she's able to control the baseline and really take the game on, she's one of the most fierce competitors out here.

"She loves to get in your face and loves to take it on. It's going to be a challenge for me to try to neutralise as best as I can, but it's certainly nice to see her out here playing her best stuff."

Working out a strategy for the match, alongside Barty, will be veteran coach Craig Tyzzer. Barty trusts him implicitly to get the plan right.

"'Tyzze' is a magician; he's able to look at a lot of different matches, look at key matches, some recent and some old, and work our plan out in looking at different conditions and things like that," Barty said in a news conference after her thumping 6-1 6-3 semi-final win against Madison Keys.

"He's the man that does all the work. I just get to go out there and have fun with it."

Barty is understating her role there, but she has turned singles into a team game, relying on the likes of Tyzzer and mindset coach Ben Crowe to steer her on the right path.

She is attempting to become the first Australian player to win this title since Chris O'Neil in 1978, so the pressure is on, and it helps that those around her help to relieve the stress.

"Everyone is equally important. We're all equal, we all play our roles," Barty said. "The most amazing thing is we all communicate really well together and get along with each other and know when it's time to back off, relax, and then when it's time to switch on and really have a crack.

"'Tyzze' has been a massive part of my life since 2016. Before that, we'd done some work together, but the work he's done in setting up an amazing group of people around us has propelled my career for both of us. The experiences we've been able to share has been remarkable.

"It starts with my family, my sisters, obviously my professional team who contribute as much time and energy into my career and help me try and live out my dreams. I cannot thank them enough for the time and effort they put in to someone else.

"Being able to enjoy it all together and lighten up when we're not focused on the match is a really important part of that."

Barty's first serve has been a huge weapon, while Collins' return of the second serve has been a significant factor behind her run. So if Barty can land enough first serves on Saturday, that could prove telling. It has helped her to save 13 of 14 break points so far in this tournament.

Giving Collins a regular look at her second serve could be costly. Collins has won more points on the return of second serve (90) than any other woman in the tournament.

Barty ranks ninth on that list but is the leader on winning points when landing a first serve, achieving an 83 per cent success rate.

Danielle Collins is relishing a "spectacular" Australian Open showdown with home favourite Ash Barty after outclassing Iga Swiatek to reach her maiden grand slam final.

Collins was imperious in her second major semi-final on Rod Laver Arena, taking just an hour and 18 minutes to beat Swiatek 6-4 6-1.

The 28-year-old American's emphatic victory was her second over a top-10 opponent in a grand slam.

Collins was relentless as a struggling Swiatek had no answer to her aggressive approach, and the 27th seed will attempt to tear up the script by denying Barty a first Australian Open title on Saturday.

It was only last April that the Florida native underwent emergency surgery for endometriosis, an extremely painful condition in which tissue similar to that which lines the uterus grows outside of it.

Collins was also diagnosed with rheumatoid arthritis in 2018, but she has broken new ground for her career at Melbourne Park, dropping only two sets en route to the final.

She said in an on-court interview following the win over Swiatek: "It feels amazing. It's been such a journey, and it doesn't happen overnight. So many years of hard work and hours at an early age on court.

"Yesterday I was talking about all the early mornings my dad would get up with me and practise before school. It's just incredible to be on this stage and especially with the health challenges. I'm just so grateful, and I couldn't be happier."

Collins beat world number one Barty to reach the Adelaide International quarter-finals last year, having lost their previous three meetings, and the world number 30 will embrace such a big occasion this weekend.

She said: "We've had some incredible battles over the years. It's going to be really spectacular, with the energy the fans bring, whether they are for me or for my opponent.

"I think we're just so grateful after everything with COVID to have incredible energy and people here supporting us."

Ash Barty is ready for "one last crack" on Saturday when she will bid to become a first home winner of the Australian Open women's singles in over 40 years.

The 25-year-old Queenslander powered through to the third grand slam final of her career with a clinical 6-1 6-3 win over Madison Keys on Thursday.

She is 2-0 for her past two finals in the majors, taking titles at the 2019 French Open and last year at Wimbledon, and has looked an unstoppable force in Melbourne.

That theory will be put to the test by Danielle Collins, the 28-year-old big-hitting American who dismantled Iga Swiatek's game in the second semi-final to reach a first slam final.

Barty is dialled in and up for the challenge, looking to land the title that was last won by an Australian when Chris O'Neil triumphed at the 1978 tournament.

"It's fun, it's brilliant to be playing in the business end of your home slam," Barty said in a news conference.

"Saturday's going to be a new experience for me. So I'll go out there and embrace it, smile, try and do the best that I can, and whatever happens, happens.

"It's been an incredible January and incredible summer for us, and I'm really looking forward to having one last crack here, to really go out and enjoy it."

Wendy Turnbull was the last Australian finalist in the women's singles, way back in 1980, and the scale of the achievement in ending the long wait is not lost on Barty, who has already won doubles and singles titles this month at the Adelaide International.

"To be in the finals weekend of your home grand slam is what a lot of Aussie players dream of," she added.

This is modesty, but Barty is now a long-standing world number one, and therefore anything but lifting the trophy would be a disappointment at this stage, with 27th seed Collins looking to spring what would be a major upset.

Barty said she was able to "play the match on our terms" against Keys, pointing to her on-court effort being a collaboration with her support team.

Keys was outplayed and her reflection on the experience of tackling Barty was blunt.

"It's tough, it sucks. She's just playing incredibly well," Keys said. "You have a game plan in your head, but she's just executing everything so well.

"She's serving incredibly well, so you don't get any free points on that; her slice is coming in so much lower and deeper than it was in the past, so it's hard to do anything on that; and then you try to play to her forehand and she can open you up there.

"She's so locked in and focused. I've played her a handful of times and this is easily the best I think she's ever been playing."

Barty, who dabbled with cricket before focusing on tennis, appears to have a work-life balance that would be the envy of many, finding it no problem to unwind once she leaves the gates of Melbourne Park. Enjoying the early Australian dominance in the women's Ashes has only brightened her mood.

"It's pretty easy for me. When I'm not here, I don't think about the tennis too much," she said. "I've got the women's Ashes to watch, which is brilliant, read a book, few coffees, and we're set."

The young Barty who first visited the Australian Open before hitting her teenage years, for a training camp, would stand in awe of the player she has become.

"I'd have been only 11 or 12 years old," she recalled. "To see how professional it was and to see everybody going about their business was really eye-opening.

"My first taste of it was in the juniors and I loved it. Being able to get a taste of that kind of lit the flame. You wonder what you can achieve."

Danielle Collins will face home favourite Ash Barty in her first grand slam final at the Australian Open after dispatching Iga Swiatek in straight sets.

Playing in only her second major semi-final at the age of 28, an assured Collins rose to the occasion to win 6-4 6-1 in dominant fashion on Rod Laver Arena.

The 27th seed from the United States was beaten by Petra Kvitova in the last four of the first grand slam of the year at Melbourne Park three years ago, but she was not to be denied on this occasion.

Swiatek was unable to become the first Polish woman to reach the final of this tournament, struggling with her serve from the start as her bid to win a second grand slam title came to a halt and Collins booked a showdown with world number one Barty on Saturday.

Collins capitalised on a shaky start from the 2020 French Open champion, breaking when the seventh seed sprayed a forehand long after double-faulting in a poor first service game.

An aggressive Collins was a double-break up at 3-0 after her out-of-sorts opponent drilled a backhand wide, but Swiatek sprung into life, winning back-to-back games to reduce the deficit to 4-2.

Swiatek trailed 5-2 after being broken for a third time as she struggled with her second serve and although Collins failed to serve out the set at the first attempt, she made no mistake second time around after firing down two aces.

The Florida native was in the zone, staying on her feet during changeovers, and she struck another blow by breaking in the first game of the second set with a cross-court backhand winner.

Swiatek's frustration mounted as her service woes continued, Collins near flawless with her backhand a potent weapon as she broke again to lead 3-0.

The ice-cool world number 30 showed not a hint of nerves, finishing off the job with another break after earning two match points with a glorious forehand winner and forcing a backhand error from Swiatek to move into the final.

DATA SLAM: Imperious Collins a class apart as Swiatek is let down by her serve

While Collins was at her very best in a brilliant performance, Swiatek looked like she did not know what had hit her.

Swiatek won only three of the 21 points behind her tentative second serve after landing only 60 per cent of her first serves in, and the 20-year-old fell into the trap of feeding Collins' dangerous backhand far too often.

Ash Barty continued her fairy-tale run at the Australian Open, crushing Madison Keys to become the first local woman to reach the singles final in 42 years.

The two-time grand slam champion continued her impressive form at Melbourne Park with a 6-1 6-3 victory over Keys on Rod Laver Arena on Thursday.

Barty, the world number one, became the first Australian woman to reach the singles final at the tournament since Wendy Turnbull in 1980.

She can become the first to win the title since Chris O'Neil in 1978 when she faces either Danielle Collins or Iga Swiatek in Saturday's final, which she will undoubtedly start as favourite.

Barty has dropped just 21 games on her way to the decider and the reigning Wimbledon champion was again ruthless against Keys, who lost her fourth grand slam semi-final in five such appearances.

The 25-year-old Barty settled well and broke the Keys serve in the opening game.

A powerful forehand created the opportunity before she delivered a cross-court winner off that wing to convert following a Keys drop shot.

Barty only made two first serves in her opening two service games yet did not lose a point.

Spurred on by a hopeful and enthusiastic home crowd, Barty's variety and depth – plus nine unforced errors in five games from Keys – helped her race into a 4-1 lead.

Keys finally won a point against the Barty serve in the sixth game, the Australian forced to save a break point before sealing the opening set in 26 minutes courtesy of a forehand return winner down the line.

The first real signs of nerves from Barty came in the fifth game of the second set, but she dug out a tough hold for 3-2.

Keys had settled, but Barty grabbed the break she was after in the sixth game with back-to-back forehand winners.

Barty looked calm throughout and that did not change as she served out the match in style, booking a spot in the final with a forehand winner.

Alize Cornet "felt out of breath all the time" during her Australian Open quarter-final loss to Danielle Collins.

Collins was too good for Cornet in a 7-5 6-1 victory on Rod Laver Arena on Wednesday, reaching her second Australian Open semi-final in four years.

The American 27th seed hit 28 winners and 29 unforced errors in a strong performance against Cornet, who was playing her maiden major quarter-final.

Cornet said Collins, who will face Iga Swiatek in the last four, never allowed her to settle at Melbourne Park.

"Well, she's very powerful, even more than what I expected. Her ball is going really fast in the air and she takes the ball super early," the Frenchwoman said.

"All the time you feel really oppressed. I felt out of breath all the time. I couldn't, like, place my game. She just never let me do it, never gave me the time to do it. Yeah, she's impressive.

"But today she was pretty quiet. She didn't scream that much. When I see her playing on TV, sometimes she's yelling, 'C'mon.' She looks like a lion.

"Today I don't think I gave her enough battle so she could express herself."

Collins was playing her first quarter-final since the 2020 French Open and dictated from the outset against Cornet.

The 28-year-old hopes her experience in the latter stages of tournaments helps her late in the Australian Open.

"Yeah, I think now that I've made quarter-finals at French and semi-finals here before, I think I can use those experiences to certainly help me in the tight-pressure moments on court. I can use that to my advantage," Collins said.

"Last time I was here in the semi-finals I had never done that before. I've made some deeper runs in tournaments since then. Hopefully I can carry the confidence that I've gained over the last couple years and be able to use that to my advantage."

Iga Swiatek came through a huge battle against Kaia Kanepi to advance to the Australian Open semi-finals on Wednesday.

Swiatek, the Polish seventh seed, made her second grand slam semi after a 4-6 7-6 (7-2) 6-3 victory over Kanepi on a warm day on Rod Laver Arena.

The 2020 French Open champion held off Kanepi, who suffered a seventh defeat in as many grand slam quarter-finals.

Swiatek fought hard and needed three hours, one minute to progress to a meeting with American 27th seed Danielle Collins.

The steadier start was made by Swiatek, with Kanepi saving break points in each of her opening three service games.

But the Pole was having some trouble with her serve, a fifth double fault giving Kanepi a break point in the seventh game, the Estonian converting with a fine forehand return winner.

Swiatek held after a gruelling 16-minute ninth game, saving four set points as the Rod Laver Arena crowd started to come to life.

Kanepi had won only one set in her six previous grand slam quarter-finals, but she eventually served out the opener against Swiatek, converting her ninth set point.

After Kanepi broke in the opening game of the second set, Swiatek – who was starting to move the veteran around the court – reeled off four straight games.

However, Kanepi responded, a pair of Swiatek double faults helping her break back in the seventh game on the way to a tie-break.

Swiatek was the more consistent of the two players in the tie-break to send the quarter-final into a deciding set.

After the players traded breaks early in the third set, Swiatek took a 3-2 lead after Kanepi sent a forehand narrowly wide before managing a tough hold in the sixth game.

Swiatek charged into a 5-2 lead and while her attempt at serving it out did not go to plan, she sealed her win with another break after a tremendous defensive point.

DATA SLAM: Swiatek hard to beat at majors

It takes a fair bit to beat Swiatek at a grand slam.

The 20-year-old is now 30-2 at majors against opponents ranked outside the top 30 after getting past world number 115 Kanepi.

Danielle Collins ended Alize Cornet's dream run and reached her second Australian Open semi-final with a straight-sets win on Wednesday.

Collins moved into the last four in Melbourne for the second time in four years thanks to a 7-5 6-1 victory on Rod Laver Arena on Australia Day.

The American 27th seed, who will face either Iga Swiatek or Kaia Kanepi in the semi-finals, was in solid form in warm conditions.

Collins was the aggressor throughout against Cornet, who was playing her maiden grand slam quarter-final in her 63rd main-draw appearance.

It was Collins who dictated the majority of points from the baseline early and landed a break of serve in the fourth game.

Cornet saved three break points, but there was no denying Collins on her fourth opportunity, a powerful return setting up a simple volley winner for a 3-1 lead.

Collins looked the more comfortable in the warm weather, but Cornet hung in there and broke back when her opponent was trying to serve out the first set, the American's backhand letting her down with three unforced errors.

But Cornet dropped the first set when serving to stay in it, saving two set points but not a third – set up with a Collins forehand winner down the line – as she framed a forehand long.

Collins crushed a forehand return winner to break serve in the second game of the second set to take complete control of proceedings.

She broke to love to grab a 4-0 lead, cruising through the second set on her way to another last-four appearance in Melbourne.

DATA SLAM: Contender Collins finding consistency

The dangerous Collins has found consistency since the back end of last year.

She is now 31-7 since July 12, 2021 and will be hard to stop by either Swiatek or Kanepi in the semi-finals.

Ash Barty was told how her backhand slice has been compared to that of Roger Federer, but the women's top seed at the Australian Open is not convinced.

Barty produced a stellar display as she saw off Jessica Pegula in Tuesday's quarter-final, losing just two games over the entire duel as the American proved no match.

Her victory sets up a semi-final clash with another American, Madison Keys, with Barty aiming to reach the final of her home grand slam for the first time.

Barty was ruthless against Pegula, firing 17 winners to her opponent's seven, while she won five of the nine break points available to her.

But it was her backhand slice – one of the most recognisable shots in the women's game today – that was particularly notable to four-time grand slam winner Jim Courier in commentary, who compared Barty in this respect to Federer.

Not that Barty was having any of it.

"That's very kind from Jim," Barty told reporters afterwards. "I think everyone's shots are unique.

"I think obviously Roger has one of the most exceptional slice backhands in the game. Mine's a long way off that. Absolutely, no stretch of the imagination we are even on the same page at all.

"But I love to use my slice, I love to get creative with it, to use it offensively and defensively. Over my career I've learnt it is a weapon for me.

"I try and use it when I have to. Sometimes I try and use it when it's my choice and I can be really, really aggressive with it.

"But being able to use it with variety and have different options has been a massive part of my game through this last couple of years of my career."

When Barty faces Keys in the semi-final, she will have already matched her personal best at the Australian Open – she also reached the last four in 2020.

But the combination of being world number one for over two years and having two grand slams under her belt is helping her maintain focus this time around.

"[It's] a bit of both. I think the process hasn't changed, but obviously the familiarity of knowing what to expect or expect how my body feels and almost be able to deal with those emotions a little bit better has probably changed and grown as I've become more experienced," she continued.

"But the processes for us haven't changed regardless of whether it's a first round of the tournament, latter stage of a grand slam, it doesn't actually matter the process before we walk out on court.

"But it's exciting, and I think also being able to embrace the excitement of being in with a chance to play deep in your home slam, it's pretty cool. I think going out there and enjoying that and really embracing that experience helps for sure."

Ash Barty was in clinical form to swat aside Jessica Pegula 6-2 6-0 in just 63 minutes and book her spot in the Australian Open semi-finals.

The world number one is still to drop a set at her home slam in Melbourne and made easy work of her opponent as Barty continued her bid to become the first female Australian singles champion since Chris O'Neil in 1978.

Barty won nine games in a row from 3-2 up in the first set to take complete command and she can now prepare for a semi-final showdown with another American in the form of Madison Keys.

A nervy-looking Pegula was rushing her shots in the early exchanges and Barty broke in the first game when a forehand cross set up a break point chance that her opponent put into the net.

Barty had chalked up 12 unforced errors by game four, but it was her aggressive tactics that had Pegula completely on the ropes and when a thumping forehand set up another break point in game seven, it was little surprise when it was converted.

By this point Barty was in complete command and Pegula had no answer to the variety of shots her opponent rained down on her.

The second set raced by in just 28 minutes, with Barty putting the finishing touch on a mightily impressive performance when Pegula put a return long on the second match point.

"Jess is an incredible person and a brilliant girl. I love to test myself against her. She's had sensational couple of years, she's definitely a top-20 player, there's plenty more to come for sure," Barty said after the match.

On reaching the semis in Melbourne for the second time after doing so in 2020, she added: "I've grown as a person, as a player, I'm a more complete tennis player.

"Credit to my team, they do so much work behind the scenes to make me the best version of myself, I love playing out here. Hopefully I've got a little bit more left."

DATA SLAM: Barty serves up a treat again

Barty defeated both Pegula and Keys en route to winning her maiden slam title at the 2019 French Open and history could be repeating itself here with the world number one playing arguably the best tennis of her career.

Behind her dominance is phenomenal success on serve. Barty is still yet to drop a set in Melbourne, and went 63 games without being broken before Amanda Anisimova did so in the previous round. Here, she lost just five points on first serve (22 of 27, 81 per cent) and gave up just a solitary break-point opportunity in the match.
