Swiatek, who defeated Britain's Emma Raducanu 6-1 6-0 in the third round, conceded just 10 points as she wrapped up the first set in 24 minutes.

She had won 20 straight games across the two matches before Germany's Lys, ranked 128th in the world, eventually managed to hold serve.

"Usually I don't feel comfortable with my game at the Australian Open, but this year it is a bit better," said Swiatek, who will replace Aryna Sabalenka as world number one if the defending champion fails to reach the semi-finals.

Lys was the first women's singles lucky loser to reach the Australian Open fourth round in the Open era and she described her run in Melbourne as "the nicest week in my life".

The 23-year-old had her flight home booked after losing in the final round of qualifying, but she was given a spot in the main draw following Anna Kalinskaya's withdrawal.

"I've had a lot of nights where I was actually talking to my parents, often with tears, asking, 'When will the time come?'," Lys said.

"Because I know I have the potential, but sometimes I was the only person that's really standing in my own way.

"Everything just came down to this week where on one side it's definitely the tennis I played, but also it was the luck in the beginning."

Swiatek will face Emma Navarro in the last eight after the American eighth seed clinched a narrow 6-4 5-7 7-5 win against Russian Daria Kasatkina, the ninth seed.

Defending champion Jannik Sinner came through a tough physical battle against Holger Rune to reach the Australian Open quarter-finals.

In a match disrupted by medical timeouts and a broken net, both Sinner and Rune seemed to struggle with the 32C heat on Rod Laver Arena.

Sinner, towards the end of the second set and into the third, was visibly shaking during the changeovers as he wrapped ice towels around his neck.

But the world number one prevailed to win 6-3 3-6 6-3 6-2 against the Dane.

"I was not feeling really well," said Italy's Sinner.

Speaking on court after his win, the 23-year-old said: "I knew in my mind even before the match I would struggle today.

"This morning was a very strange morning because I didn't even warm up today, trying to go on court as fit as I could."

He will face Alex de Minaur, the last Australian standing in the singles, next after he claimed an assured 6-0 7-6 (7-5) 6-3 win over American Alex Michelsen to reach the Melbourne last eight for the first time.

"There's nothing I want more than to play well here in Australia in front of you guys. I'm glad I finally made it to the quarter-finals here but let's go for bigger and better things," said eighth seed De Minaur.

Elsewhere, fellow Italian Lorenzo Sonego beat American qualifier Learner Tien 6-3 6-2 3-6 6-1 to reach his first Grand Slam quarter-final.

Sonego will play 21st seed Ben Shelton next after the American's fourth-round opponent, Frenchman Gael Monfils, retired with a back issue while trailing 7-6 (7-3) 6-7 (3-7) 7-6 (7-2) 1-0.

Djokovic, a 10-time champion at Melbourne Park, plays world number three Carlos Alcaraz in the quarter-finals on Tuesday.

Channel Nine also apologised, saying "no harm was intended towards Novak or his fans".

The Serbian Council of Australia has called for Jones to be sacked, saying his comments were "offensive, racist and only serve to incite further discrimination of Australian-Serbs".

Jones said he particularly felt he had "overstepped the mark" with his "kick him out" comment - which he accepted could be interpreted as a reference to Djokovic's 2022 deportation from Australia because of the country's Covid-19 regulations.

"That has angered Novak I completely understand that," said Jones.

"It has been an unfortunate situation and one of personal angst for Novak and personal angst for me as well. The priority now is to focus on the tennis. He has an amazing match and I hope he can focus on that.

"I can only again tell Novak what I told him 48 hours ago which is I do apologise if he feels I disrespected him.

"I agreed to meet him in person, they came back and yes, that hasn't transpired yet but I hope it will happen in the next 24 hours."

Tennis Australia said: "Novak acknowledges the apology has been given in public as requested and is now moving on and focusing on his next match."

Satomi Watanabe and Marwan Elshorbagy have won the Squash in the Land 2025 titles, recording convincing wins over Amanda Sobhy and Tarek Momen respectively on finals day in Cleveland.

Kicking off the days play, the matchup between Watanabe and Sobhy represented a significant opportunity for both players, with Watanabe targeting the biggest title of her career and Sobhy seeking her first tournament win since returning from a second career-threatening achilles injury.

Both players had needed all five games to get through their semi-final encounters, with the American fighting back from 2-1, 5-1 down to beat Rowan Elaraby, while Watanabe recorded an epic win over rising star Amina Orfi, clinching a fifth-game tiebreak 12-10.

What a performance from @x_satosq_x to claim the biggest title of her career so far #Squashintheland pic.twitter.com/j0KI0UzeBq

That result came 48 hours after the Japanese star had knocked out No.1 seed Georgina Kennedy in the quarter-finals, with Watanabe saying after her semi-final win that this week has been some of the best squash of her career.

She continued that fine form in the early stages of this final, too, showing no signs of being overawed by the occasion or the American crowd.

Cutting a relaxed figure, Watanabe moved Sobhy around the court well en route to a 10-5 lead, and while Sobhy mounted a comeback to close the score back to 10-8, the World No.12 slammed the door shut with a brilliant serve return winner down the line.

The action was taking place at Clevelands Outcalt Theatre in Playhouse Square, the second-biggest theatre district in the USA behind only New York and Watanabe continued to put on a show early in game two, quickly leading 5-2.

Sobhy found her feet and moved back to 7-7, rushing Watanabe, forcing her into a handful of errors, but the 26-year-old responded in kind, producing three outstanding points to stop another comeback in its tracks and take a two-game lead.

Watanabes backhand had been outstanding throughout the first two games and she opened game three with another clinical volley drop on the same side, kickstarting a charge towards the title that would not let up.

From 4-3 down she won seven points on the bounce to bring up six match balls, seeing the first two saved before getting over the line on the third, securing the first Silver-level title of her career.

I dont think I can describe how I feel at the moment with words, she said moments after victory.

But Im definitely really, really happy that I fought through the whole week. It was one of my toughest tournaments as well so Im just over the moon to win this tournament, and I think its my biggest title.

I think I was really calm today in knowing what was happening on court. I made some errors here and there but she was putting me under a lot of pressure as well, so Im happy with how I played today.

At the point of 10-4 [in the third] I thought I was really pushing her and then she hit the really, really nice lob at the corner and I just could not get it back, I was like alright, ok, here we go, its a really nervous time, but I was just trying to relax my arm, make sure I hit the length again.

That performance was swiftly followed by an equally impressive display from mens No.4 seed Elshorbagy, who needed just 35 minutes to see off Momen.

The Egyptian had beaten top seed Mohamed Elshorbagy 24 hours earlier, denying the Cleveland crowd the chance of all-Elshorbagy final, while Marwan had put a slow start behind him to see off Karim Abdel Gawad in four.

Those results set up this final showdown, the 14th PSA Tour meeting between the two players but the first in a final.

Title #15 in the bag for @maelshorbagy #SquashintheLand pic.twitter.com/1zBBSsuHPj

PSA Squash Tour (@PSASquashTour) January 19, 2025

Elshorbagy had only won two of the previous 13 matchups but he looked sharp from the off in this encounter, taking less than 10 minutes to take the opening game.

Momen would have been hoping for a turnaround similar to that which he produced in his semi-final win over Mohamed Elshorbagy, when he lost the opening game before winning the next three, but instead he made the worst possible start to game two, losing seven of the first eight points.

Elshorbagy was attacking well to the front and hitting his targets well in the back corners too, and while Momen closed the gap back to 9-6, hed left himself far too much to do, going down 11-6.

The crowds at Clevelands Outcalt Theatre had been treated to some spectacular comebacks in this years event but any hopes of another one here were soon dashed in the early stages of game three, as Elshorbagy continued to play exceptionally sharp squash.

He stormed into a 5-1 lead and didnt give the Egyptian a look-in, closing the door with another 11-6 win when an ambitious backhand dropshot attempt from Momen fell short on match ball.

Im very happy with the week, Elshorbagy said after collecting his trophy.

To come here and win means a lot to me. It was a tough match playing Tarek today, I dont have the best record against him of course and Ive already played him twice this season but I woke up today and mentally, I was telling myself that I have nothing to lose, and to stay calm as much as possible, try to play good squash and stick to my tactics.

Im glad it worked, I felt very sharp from the beginning, I didnt lose my focus through the whole three games so I was happy with my solid performance today.

Fit-again Dan Sheehan and James Lowe are set to return to action for Leinster this week before linking up with Ireland's Six Nations squad.

Hooker Sheehan, 26, has not played since sustaining an anterior cruciate ligament injury during Ireland's defeat by South Africa in July.

New Zealand-born wing Lowe, 32, has been out since Ireland's Autumn Nations Series win over Australia on 30 November with a calf problem.

On Monday, Leinster confirmed both players are available for Saturday's United Rugby Championship match against the Stormers at Aviva Stadium.

Sheehan and Lowe returned to full training last week but did not feature in Saturday's Investec Champions Cup win over Bath.

Back row Will Connors is also available for Leinster, who have won all 13 of their games in the URC and Champions Cup this season.

The Ireland squad gathered in Dublin on Monday before travelling to Portugal for a training camp.

Ireland begin their bid for a third successive Six Nations title at home to England on 1 February.

"We have a Six Nations campaign and Rugby World Cup to prepare for in what promises to be the biggest year in the history of women's rugby.

"We have work to do but having coached, and coached against, the Welsh internationals in England, I know we have the players to make the nation proud."

As well as coaching the PWR team, Lynn oversaw the rugby programme at Hartpury College and University.

He was unveiled by the Welsh Rugby Union (WRU) at the Principality Stadium on Monday.

Lynn had made no secret of his ambition to coach at international level, but played down links to the role a few weeks after Cunningham's exit.

His appointment could be a good fit for Wales, with Gloucester-Hartpury home to a large contingent of Welsh internationals including Hannah Jones, Sisilia Tuipulotu, Lleucu George, Bethan Lewis, Kate Williams and Kelsey Jones.

He will work closely with Belinda Moore, who was recently named the WRU's head of women's rugby in Wales, a new high-profile role.

WRU chief executive Abi Tierney said Lynn's appointment "underlines the importance" of Wales' women's team and emphasises how the union want the side to progress.

She added: "His ability as a coach is second to none as he has proved with two back-to-back titles in the PWR.

"I am delighted he has accepted the role. He was the outstanding candidate among a field of high-calibre of applicants who recognised what a prestigious and important role it is to be the Wales head coach."

Saracens' Phil Morrow will join England as head of performance at the end of the season, after an initial attempt to recruit him was blocked by Premiership clubs.

England had hoped to bring in Morrow last autumn, but Saracens would only allow him to take up the role midway though a campaign if he continued with his club duties.

Premiership clubs blocked the job-sharing proposal over concerns of a potential conflict of interest, with England's strength and conditioning department now working more closely with top-flight sides over star players' fitness and recovery programmes as part the new Professional Game Agreement.

However, Morrow will step down from his Saracens post at the end of the domestic season to make the switch.

The situation means England will continue with a reduced conditioning department through the Six Nations.

Gloucester fitness coach Dan Tobin was recruited in September after Aled Walters switched to Ireland and long-serving Tom Tombleson left the camp.

"I'm incredibly proud to be joining England Rugby," said Morrow.

"I've worked in the Premiership for a long time and week in, week out I see the quality of the players we have in England. The clubs do an outstanding job of developing these players, and I look forward to working with them to help them reach their full potential.

"Under Steve [Borthwick] the England team is in an exciting phase of growth and development, and I cannot wait to start contributing to the team's future success."

Morrow has spent almost 14 years with Saracens, during which they have won five Premiership titles and three European crowns.

He was also part of the strength and conditioning staff on the British and Irish Lions tour to New Zealand in 2017.

As part of his role, Humphreys - who won 72 caps for Ireland and captained Ulster to the European Cup in 1999 - says he wants to return all four Irish provincial teams to the "top end of Europe".

Leinster, Munster and Ulster have all qualified for this season's Investec Champions Cup knockout rounds while Connacht have reached the last 16 in the second-tier Challenge Cup.

But while Leinster have played in each of the last three Champions Cup finals (losing all three), Ulster have not featured in a decider since 2012, Munster have been absent from the showpiece since winning the competition in 2008 while Connacht have not qualified since the 2021-22 season.

Leinster also provide the majority of players to the Irish national team, with 23 of Easterby's 36-man Six Nations squad selected from Leo Cullen's side.

Humphreys, however, does not believe such an imbalance will be "detrimental" for Irish rugby in the long run.

"For me, it's very simple: it's not about taking anything away from Leinster," he said.

"No business in the world we'd look at the strongest asset and say 'we have to take a bit away' to do something else.

"For me, it's about making sure that Leinster not just retain their status in European rugby but go on and win some European Cups, they've been so close.

"For the long-term success of Irish rugby, four competitive provinces, we have to get to that point."

During his time as Ulster's director of rugby, Humphreys recruited high-profile southern hemisphere players such as Ruan Pienaar, Johann Muller and John Afoa.

And with New Zealand's Jordie Barrett having starred in the early stages of his loan spell at Leinster, Humphreys says there is "huge value" in having established overseas internationals playing alongside homegrown players in Ireland.

"For me, the model is: top quality international players playing alongside top quality Irish players.

"That, to me, is not a solution but a way to make sure Irish rugby becomes stronger at all levels of the game."

Analysis - Tom English, BBC Scotland's chief sport writer

The grim confirmation of Sione Tuipulotu's Six Nations-ending injury was expected but it still landed with a thud nonetheless.

Tuipulotu is one of the form inside centres in the game; a captain, a physical brute, an artist, an inspiration to his team. He's a pretty rare amalgam of world-class bludgeon and world-class rapier.

His absence - and that of the outstanding lock Scott Cummings - has seen Scottish optimism, racing along merrily last week, reduced to a slow crawl. Glasgow have also suffered a double blow in the loss of two critical operators.

Tuipulotu's partnership with Huw Jones is a cosmic blend. Now an alternative is needed. Jones and his excellent Warriors' team-mate, Tom Jordan, don't pack enough physical punch for Test rugby as a duo. Franco Smith never plays them together at 12-13 for Glasgow.

The same could be said for Rory Hutchinson, the dangerous Northampton centre. A Hutchinson-Jones combo lacks enough muscle for the unforgiving fields of Six Nations rugby.

Most likely, it's going to be another Warriors pair, Stafford McDowall and Jones in the midfield in the championship.

McDowall is a tough operator and Glasgow's captain but nobody inside the Scotland camp is pretending Tuipulotu's absence is anything other than a nightmare.

As for Tuipulotu's fitness for the Lions - pretty much every pundit in all four nations has picked him at 12 in the Test series - let's just hope that his operation is successful and that his recovery is swift.

Losing Cummings is also hellish news given his power game and his form. Grant Gilchrist and Jonny Gray will surely now start against Italy in the opening day of the championship, but their back-up, Glasgow's Max Williamson, is also out for the tournament, so there are problems in multiple places.

Glasgow head coach Smith, like Gregor Townsend, must be a disappointed man today.

Scotland began their Six Nations season with two home games back-to-back, with Italy and then Ireland coming to Murrayfield in the first nine days of February.

The odds on Townsend's team causing a sensation this season will have drifted with Monday's news.
