Emma Raducanu struggled with a stomach bug during a marathon second-round loss to Wang Yafan at the Australian Open.

The former US Open champion, playing only her fourth match since returning from eight months out and three surgeries, had battled back strongly from a set and a break down to force a decider.

But Raducanu then began to show a lot of discomfort, clutching at her chest and abdomen before calling the trainer two games in.

She had her blood pressure checked and took some pills before resuming, and she battled hard to try to turn the match around but Wang held firm to win 6-4 4-6 6-4 after two hours and 55 minutes.

It appeared Raducanu was struggling with her breathing but she revealed in her press conference that she was feeling sick having gone into the contest under the weather.

“I think I just had a bit of a stomach bug beforehand,” she said. “Now I feel a little bit better. I had some time.

“During the match, third set I was 30-0 up serving. Then all of a sudden I just felt so sick, just really weak and nauseous. Throughout the third set I think everyone could see it was a bit of a battle.

“Like physically, body-wise, I felt fine. It was more I was throwing up in my mouth. Then after the match, it came out. Now I’m OK. I’ll get over it. It just sucks with the timing.

“I was actually feeling good about my tennis. Mentally, I don’t know why, I just felt really composed the entire time. Even in the first set when I was making a ton of errors with the wind, I kind of always had this feeling that I was coming back, just tidy up the errors. I felt pretty composed throughout.”

Raducanu is no stranger to medical time-outs and retirements but she was determined to keep going this time.

“I’ve been in that situation before in matches, whether it was with illness or injury, and retired a few times,” she said.

“With what I went through last year, you feel awful right now, at some points I couldn’t really see the ball very well, but I think it’s made me so much tougher. There was no way I was going to pull out. She was going to have to beat me, and she did. She served it out.”

Raducanu’s exit followed those of Katie Boulter and Jack Draper and means Cameron Norrie, who battled from two sets down earlier to beat Giulio Zeppieri, is the only British player through to the third round.

Raducanu comfortably won her first-round match against Shelby Rogers, but the American looked very rusty after a long break herself which made it difficult to gauge the 21-year-old’s true level.

This was a much bigger test, with Wang a former top-50 player now ranked 94 who is still working her way back up the game after choosing not to travel amid China’s restrictive Covid policies.

The 29-year-old’s game initially held up better than Raducanu’s in the breezy conditions and she looked in control at one set and 2-0 up, at which point the British player cut down her errors and fought her way back into the contest.

She broke to lead 5-3 with a sizzling cross-court winner but tentativeness crept in as she tried to serve out the set, with two chances going begging.

Raducanu did not let the disappointment affect her, though, and refused to be hesitant when more chances arrived on Wang’s serve, drilling a backhand winner to clinch a mammoth 65-minute set.

At that stage it appeared Raducanu was the favourite but her physical issues quickly became apparent and she was unable to turn the match back around in her favour.

She leaves Australia greatly encouraged for what is to come, though, saying: “There were doubts whether I would be able to make the Australian Open trip.

“I think that to be here is a bonus, a good starting point I would say, because I started putting good practice sessions together with (coach) Nick (Cavaday), we’re doing good work off the court.

“I’m feeling very positive. I really just want to play a full season. The encouraging thing is, even though I played two back-to-back three-setters in Auckland, a three-setter today, body-wise, strength-wise, I didn’t come up with any random niggles.

“It was just me throwing up. That’s fine. That’s not normal, but it’s like a one-off.”

Jack Draper and Katie Boulter have set their sights on being seeded for Wimbledon after losing in the second round of the Australian Open.

Both found themselves up against highly-ranked opponents and were unable to cause upsets, with Draper losing 6-2 3-6 6-3 7-5 to 14th seed Tommy Paul, while Boulter was beaten 6-3 6-3 by 12th seed Zheng Qinwen.

Draper was particularly frustrated having beaten American Paul in both their previous meetings, including last week in Adelaide.

But, although he pulled up well physically from his dramatic first-round match, which he ended vomiting into a bin, the 22-year-old was unable to find his best tennis.

“He definitely came out playing really well,” said Draper. “I think he knew what he was up against. I think I won all four sets against him that I played.

“I definitely feel like I haven’t really got used to conditions this week at all. I just have been struggling to find my level. Obviously when you are playing a top player like that, if they’re playing well, there are very small margins in it. He was the better player today. He deserved to win.”

Draper is impatient to get to the sort of ranking he knows his talent merits, and it appears physically he is becoming more durable.

Being among the seeds at slams means guaranteeing avoiding higher-ranked players in the first two rounds and, having missed much of last season through injury, Draper now has a big opportunity to climb quickly.

He said: “I feel fit. I’m ready to keep going. I’m very motivated to keep getting better.

“So hopefully, by grass, if I keep my form up, if I stay fit, keep giving myself the opportunities to compete, then I’m going to be hopefully seeded for Wimbledon. And that’s kind of my goal now.”

It is the same for Boulter, who was disappointed to lose to Zheng but showed again that she can mix it with the top players.

The 21-year-old Chinese player is one of the game’s up-and-coming stars but the contest was closer than the score suggested.

Boulter will leave Australia with the best win of her career under her belt against Jessica Pegula at the United Cup earlier this month and a lot of belief in her prospects for the rest of the season.

“This trip has been great,” she said. “For me it’s about week in, week out playing these girls, trying to get big wins against the best players in the world. I gave myself opportunities to do that this week. I found myself winning a couple of matches a few weeks ago as well.

“For me, it is a massive step in the right direction. I’m going to keep working very, very hard. I know my game is there. Today it just wasn’t quite there.

“I would much rather play (her) in the third round, the fourth round to get myself into the tournament more and more and be playing on the bigger courts, which ultimately is more about the tennis than the conditions.

“So my next step for me is to challenge myself to get to 32 and push on from there.”

Banbridge could head straight for the Ryanair Chase at the Cheltenham Festival following his successful reappearance at Kempton.

Joseph O’Brien’s charge proved his worth at the highest level as a novice over fences last term, placing in the Drinmore at Fairyhouse and the Irish Arkle at Leopardstown before enjoying his day in the sun in the Manifesto Novices’ Chase at Aintree in the spring.

Banbridge made his first competitive appearance in nine months in last weekend’s Silviniaco Conti Chase, and O’Brien believes his defeat of the race-fit Pic D’Orhy is clear evidence the eight-year-old has improved since last season.

He said: “It was a lovely ride from J J (Slevin) and a lovely performance from the horse. It was a career-best on figures and we’re looking forward to the spring with him.

“You’re always hoping they might put up a nice performance on their reappearance and he has been delayed a couple of times so he was a little bit rusty, particularly in the straight jumping the second- and third-last, but he got a good jump at the last and went and won nicely.

“It’s one thing being a Grade One novice, but it’s another jump up to hold your own in open company. It looks as though he might be able to do that in the spring.”

Banbridge is a 5-1 shot with Paddy Power for the Ryanair Chase, and while he will be aimed for Cheltenham, O’Brien hinted he could look elsewhere should testing conditions prevail in the Cotswolds, adding: “The programme will map itself out and the Ryanair is the obvious next spot for him, but we’ll be watching the weather.”

Cameron Norrie was pleased to show his mental fortitude in a gritty comeback victory over Giulio Zeppieri in the second round of the Australian Open.

A strong wind and two rain breaks, coupled with an inspired opponent, made life extremely difficult for the 19th seed but he battled to a 3-6 6-7 (4) 6-2 6-4 6-4 victory to set up a clash with 11th seed Casper Ruud.

Norrie took a medical timeout early in the match for treatment to his right knee and was also shaking out the troublesome left wrist that prompted his withdrawal from a tournament in Auckland last week.

The British number one is confident the issues will not hinder his chances, and took heart from being able to play through the discomfort.

He said: “I feel great right now. I think it will be interesting to see how I pull up. The legs feel great. Hopefully the wrist is good, as well. I think it’s just a good lesson to learn that I can play with a few distractions going on.

“I don’t think the knee was anything. I think it just was a bit more precautionary. Actually it loosened up. I think it was probably just being very tense from the match.

“I think I have to make sure I warm up really well. Once the wrist is warm, then I’m not feeling it. So I think it’s just trying to stay warm and play and not think about it. I was able to prove that in the first couple matches.

“I think I was making it a bigger deal than it probably was in the beginning of the match. I was addressing it too much. Once I switched my focus and my energy towards how to win and how to play and how to win points, I think that was key. I think it was a good match mentally for me.”

It is the third time Norrie has recovered from two sets down to win after his Davis Cup debut against Roberto Bautista Agut in 2018 and a first-round win over Diego Schwartzman at the US Open four years ago.

For the best part of two sets Norrie was unable to cope with the power of Zeppieri, ranked 133 but in form after coming through qualifying, who bullied the British number one with his serve and forehand.

In cool, windy conditions, Norrie did not get into the contest until late in the second set, when he gave himself the chance to level proceedings only to lose the tie-break.

The third set was affected by two rain delays but Norrie had changed the momentum and he hung tough through a close deciding set before gaining the crucial break of serve at 5-5.

“He came out firing and basically took the racket out of my hand for the first hour and a half,” said Norrie.

“I was really flat. I was just kind of complaining to myself about little things. Wasn’t moving. Wasn’t playing clear. I wasn’t thinking clearly.

“I just managed to rise the energy a little bit. He dropped slightly. I think, when the first rain delay came, I just felt a little bit more calmer coming out to court. I got a chance to chat with my coach and change the game plan a little bit, to play a little bit more to the backhand side.

“But I was really pleased more mentally how I managed to switch it around. I was not feeling good on the court. It was not great, but I managed to finish the match. I managed my serve so well from the start of the third.”

Norrie finds himself in the now familiar position of being the only British singles player left, and he will try to claim a first win over Ruud to reach the fourth round for the first time.

Gavin Cromwell is leaning towards running his dual Stayers’ Hurdle hero Flooring Porter in the National Hunt Chase at this year’s Cheltenham Festival.

The nine-year-old dominated from the front to lift the Stayers’ crown in 2021 and 2022, but having had to make do with fourth place when bidding for the hat-trick last season, he has this term embarked on a career over fences.

He made a successful start at Cheltenham in October, but has since had his limitations exposed in Grade Two and Grade One company at Punchestown and Leopardstown respectively.

With Cromwell deciding against entering his stable star for the Brown Advisory Novices’ Chase, he faces a straight choice between the three-mile-six-furlong National Hunt Chase or switching back to the smaller obstacles for the Stayers’ Hurdle, with the former currently his preferred option.

“It (National Hunt Chase) is probably more likely anyway, but we’re keeping an open mind and seeing how things go with everyone else and what way the races are closer to the time,” he said.

“He’s very versatile, so there’s no reason why he couldn’t switch back to the Stayers’ Hurdle.”

Keith Donoghue has taken over in the saddle from Danny Mullins this season, but neither will be eligible to ride in the National Hunt Chase, which is of course confined to amateur jockeys.

Asked whether he had considered who might take the mount if Flooring Porter does line up over fences, Cromwell added: “That is obviously a bit of a dilemma, but we’ll work on that.”

A Plus Tard, winner of the 2022 Cheltenham Gold Cup, has been retired from racing.

Owned by Cheveley Park Stud and trained by Henry de Bromhead, A Plus Tard gave jockey Rachael Blackmore a historic victory in the Prestbury Park feature as she became the first woman to ride the winner of jump racing’s blue riband.

The 10-year-old rocketed to a 15-length success that day, supplementing three previous Grade One wins, including a 22-length verdict in the 2021 Betfair Chase.

However, A Plus Tard has struggled to make his mark since that Gold Cup win, pulling up on two occasions and finishing third at Aintree in April before bowing out when unplaced in the Savills Chase at Leopardstown last month.

Richard Thompson, director of Cheveley Park Stud, paid tribute to the gelding who realised the dream of his late father, David, when winning at Cheltenham.

He said in a statement: “My father and I sat down in early 2018 and agreed a plan to buy some National Hunt horses to be trained in Ireland with the aim of winning the Cheltenham Gold Cup.

“Just over four years later, we achieved this objective when Rachael Blackmore rode A Plus Tard to victory in front of 70,000 people at the first Cheltenham Festival post Covid.

“My father watched A Plus Tard win the Savills Chase in a thrilling finish on television on December 28, 2020. He died the very next day. It was the last horse race he ever watched.

“A Plus Tard was also the first Cheltenham winner in the red, white and blue Cheveley Park Stud colours and also Rachael Blackmore’s first winner at Cheltenham in the 2019 Listed Close Brothers Novices’ Chase. Rachael rode him to five of his six victories and Darragh O’Keeffe rode him in the other one.

“For all of the above reasons, A Plus Tard will always be a very special horse in the history of my parents’ ownership of Cheveley Park Stud.

“A special thank you to Henry de Bromhead and all the team at Knockeen and to Rachael too. To win the Cheltenham Gold Cup is the Holy Grail of National Hunt racing and we will never forget March 18, 2022.”

A Plus Tard will remain at De Bromhead’s Knockeen yard in the immediate future before returning to Cheveley Park in Newmarket to enjoy his retirement.

De Bromhead added: “A Plus Tard was our first horse to train for Cheveley Park Stud and the Thompson Family. He was bought from France by Alex Elliot and gave us many memorable days, culminating in the 2022 Gold Cup.

“He was sublime that day, not only visually impressive, but also one of the highest rated winners of the Gold Cup in the last 30 years, as well as being one of the best horses we have ever had in our yard.

“We were delighted when this very special horse won Cheveley Park Stud their first Gold Cup.”

A Plus Tard bows out the winner of eight of his 23 career starts, with over £957,000 in prize money.

Exeter boss Rob Baxter has backed “calm character” Immanuel Feyi-Waboso to make the most of his opportunity with England.

The 21-year-old Exeter wing was born in Cardiff and spoke with Wales defence coach Mike Forshaw ahead of this season’s Guinness Six Nations Championship.

But Feyi-Waboso also qualified for England, and he has taken that route, being named among seven uncapped players in Steve Borthwick’s squad for the tournament.

The Exeter University medical student has excelled in Chiefs colours this season, scoring some memorable tries and consistently proving a handful for opposition defences.

Feyi-Waboso will potentially be up against the likes of Elliot Daly and Tommy Freeman for a starting place against England’s opening Six Nations opponents Italy on February 3.

And Baxter believes he will thrive in the England environment, having impressed him at every turn this term.

“He has maintained decent form on the field, hence his call-up, and he is a calm character on the whole. I would like to think he will take it in his stride,” Baxter said.

“At the same time, you get relatively short time in the England camps to prove a point, so he is going to have to step in there and get on with things and drive his own opportunity.

“I think he is just the kind of guy who might well do that. I don’t have any fears for him.

“I think he is a guy with a very bright future in the game, and this is just one of those steps for him.

“One of his dreams is playing international rugby, winning trophies and playing Premiership rugby, but another big part of his dream is qualifying to be a doctor. It is not just always about rugby.

“He is settled at Exeter University and is happy the way the course is going, and with us. Once he goes to play for Wales, that is it, there is no get-out for him.

“If he wants to keep playing internationally, he has to go back to Wales, there is no leeway there for him.

“These are things people have to take into account when they wonder what he is doing. He has got big decisions to make, and it is not all one country over another.

“He has got himself up and running in his medical career. From what I can gather, England were in contact with him earlier than Wales, so there are a few factors.”

Feyi-Waboso will report for England duty next week alongside his Exeter colleagues Ethan Roots and Henry Slade, with Slade being recalled after missing out on the World Cup in France.

Baxter added: “The biggest thing I will say before they leave us after this weekend will be to make sure they are confident being themselves, and the qualities they have shown are the reason they got selected.

“If someone wants to pick you because of the way you play in club rugby, those are the attributes you have to show when you play.

“I always look at 100-cap international players, and nine times out of 10 when you watch them play they play pretty much the same when they play in a club game.

“They have that confidence in the way they play at club level, and if they do that well it transposes well into the international game.

“Henry getting back into the England set-up is a celebration for him, but it is a celebration for the team as well, and I really hope the team feel like that.

“He has almost, not reinvented himself, because he hasn’t had to because he is a very, very good player, but he has certainly reinvigorated himself.

“He is certainly playing with a pace, energy, enthusiasm and drive that is very evident.”

Emma Raducanu suffered more physical difficulties in a second-round Australian Open exit to China’s Wang Yafan.

The former US Open champion, playing only her fourth match since returning from eight months out and three surgeries, had battled back strongly from a set and a break down to force a deciding set.

But Raducanu then appeared to struggle with breathing difficulties, clutching at her chest and abdomen before calling the trainer after two games.

She had her blood pressure checked and took some pills before resuming, and she battled hard to try to turn the match around but Wang held firm to win 6-4 4-6 6-4 after two hours and 55 minutes.

Raducanu’s exit followed those of Katie Boulter and Jack Draper and means Cameron Norrie, who battled from two sets down earlier to beat Giulio Zeppieri, is the only British player through to the third round.

Raducanu comfortably won her first-round match against Shelby Rogers, but the American looked very rusty after a long break herself which made it difficult to gauge the 21-year-old’s true level.

This was a much bigger test, with Wang a former top-50 player now ranked 94 who is still working her way back up the game after choosing not to travel amid China’s restrictive Covid policies.

The 29-year-old’s game initially held up better than Raducanu’s in the breezy conditions and she opened a 5-2 lead in the first set.

The match was again being played on the relatively small 1573 Arena, and queues stretched from each entrance with fans eager to watch the contest.

Raducanu had the majority of the support, and she sparked hopes of a comeback by winning consecutive games to make it 5-4, but Wang served it out at the second time of asking.

There were too many errors off the racket of the British player, and she dropped serve again at the start of the second set.

But Raducanu dug in and gradually began to find her range, finally taking her fifth break point in a long fourth game to draw level.

The 21-year-old is determined to stick to an aggressive game plan following her comeback and her forehand was now looking the dominant shot.

She broke to lead 5-3 with a sizzling cross-court winner but tentativeness crept in as she tried to serve out the set, with two chances going begging.

Raducanu did not let the disappointment affect her, though, and refused to be hesitant when more chances arrived on Wang’s serve, drilling a backhand winner to clinch a mammoth 65-minute set.

Both players took a bathroom break but that did not alleviate the discomfort Raducanu was feeling, and there was doubt over whether she would be able to continue.

She improved physically again as the match went on and will feel she could have turned the set around but a final backhand into the net signalled her demise.

Saturday’s BetMGM Clarence House Chase fixture at Ascot is already in major doubt after an inspection was called for 4pm this afternoon.

The Berkshire circuit is due to host a seven-race card, with the Grade One feature set to stage a mouthwatering rematch between old foes El Fabiolo and Jonbon after the top-class pair were both declared as part of a four-runner field on Thursday morning.

However, it appears increasingly unlikely the clash will take place this weekend after temperatures dipped even lower than forecast on Wednesday night.

“We were expecting to get down to minus 4C last night, but we actually got down to minus 6C,” said clerk of the course Chris Stickels.

“It’s still colder than minus 2C now here and the forecast for tonight is for temperatures to get down to minus 4C.

“The course is frozen under the covers and with the forecast we’ve got, I would imagine we’re going to be unable to race. There’s nothing at this stage that gives me confidence.”

An inspection has also been called ahead of Saturday’s meeting at Haydock, with officials set to check on conditions at 8am on Friday.

Clerk of the course Kirkland Tellwright admits it is a “long shot” the card, which features the Sky Bet Peter Marsh Chase, will take place, but given a rise in temperatures is forecast on Friday, he will wait a little longer before making a final decision.

He said: “It’s a long shot but we have got one eye on this thaw.

“We will probably fail to race, but we think it’s worth running with it a little bit longer in case that thaw comes a bit earlier than expected.

“We got to minus 7C last night so the majority of the track is frozen, including some areas under the covers, so we have a steep gradient to climb.”

Carlos Alcaraz came through a tough four-set battle with Italy’s Lorenzo Sonego on a day of close encounters for the big names at the Australian Open.

Novak Djokovic’s struggles will have given heart to his rivals but few are finding the early stages of the tournament straightforward, and second seed Alcaraz needed three hours and 25 minutes to defeat Sonego 6-4 6-7 (3) 6-3 7-6 (3).

In a match full of shot-making, Alcaraz topped the highlight reel with two winners around the net post.

“I didn’t feel I had downs in the match,” said the Spaniard. “In the tie-break, he started to play an unbelievable game. I think he made some big returns after a good first serve from me.

“I think probably I could do something else in the tie-break. But the level that he played, it was really, really high.”

Sixth seed Alexander Zverev and 11th seed Casper Ruud both needed fifth-set tie-breaks to edge into round three.

Zverev looked in deep trouble down two sets to one against Slovakian qualifier Lukas Klein before recovering to win 7-5 3-6 4-6 7-6 (5) 7-6 (10/7).

The German said of his opponent: “I didn’t know him at all. To be honest, if he would have been in a room, I would have not known that he’s my opponent.

“But he played extremely well. He played very, very aggressive, hitting every single ball as hard as he could from both sides, I feel like. A lot of the times I was a spectator in the match. I was just witnessing whether he’s going to hit a winner or miss.

“That’s not a nice feeling to be in, especially in the important moments, but I’m happy that I managed to win.”

Zverev next faces American teenager Alex Michelsen, who knocked out last year’s quarter-finalist Jiri Lehecka.

Ruud was given a huge battle by Australian Max Purcell, who twice fought back from a set down to force a decider before the Norwegian prevailed 6-3 6-7 (5) 6-3 3-6 7-6 (10/7).

“He’s a really tricky player and a great tennis player in my eyes, even though he plays different from others,” said Ruud.

“I’m very happy with the win. He beat me in Cincinnati. The plan was to do things better from that time, and I think I did, and that was just enough to win the match.”
