The 23-year-old has had a disrupted build-up to the Australian Open, with a hip problem causing him to miss the United Cup and cancel a training camp with four-time major champion Carlos Alcaraz.

Draper said he had been trying to adapt to the heat by using saunas and "bikes in hot bubbles", alongside arriving in Australia two-and-a-half weeks before the Grand Slam tournament began.

"It's not just the tennis, it's a big mental game as well and it's how we recover after points and deal with stress in general, whether that be the tennis or the conditions," Draper said.

"I think my prep for the heat this year has been a lot better than previous years."

Draper, who is seeded 15th at Melbourne Park, has been practising alongside world number one Sinner and 24-time Grand Slam champion Novak Djokovic before his first-round match against Argentina's Mariano Navone on Monday.

"They just bring such a high quality to the practice court It's really great to be able to spar with that kind of level of intensity and work ethic," Draper added.

Burrage was at a career-high of 84th in the world rankings in February when she needed surgery on a snapped tendon in her wrist.

But she suffered another blow in April as she prepared to return to competitive action.

Burrage ruptured an ankle ligament in a practice session with British number one Katie Boulter and, although she did not require surgery, she missed another 10 weeks.

She finally returned to court in September at a WTA event in Monastir before the emotional moment in November where she questioned her future during practice at the National Tennis Centre.

It was a sliding doors moment. Burrage fought on. A week later she reached the final of a Futures event in Slovakia, then lifted the trophy in Dubai straight afterwards.

"That's the funny thing about tennis," said Burrage, who is playing in Melbourne under a protected ranking and faces French qualifier Leolia Jeanjean in the first round.

"Literally five days later, I started in Slovakia, made the final and then I win the biggest title of my career in Dubai.

"It was very up and down. Those six months were really, really hard."

Asked what stopped her quitting, she said: "For some reason, I love this crazy sport. That's what kept me going.

"The fight, being here [in Melbourne], working hard, working towards something.

"I feel like I've got so much more to give."

Since her 'fairytale of New York', Emma Raducanu has needed to show a great deal of patience.

Coping with the intense scrutiny that followed her stunning 2021 US Open triumph was tough, as was the physicality of going full-time on the WTA Tour.

There were signs of progress last year as she made her comeback from wrist and ankle surgeries in 2023.

Signing up a full-time fitness trainer has signalled Raducanu's intention to become the athlete she "knows she can be" but there was familiar blow when she pulled out of the season-opening WTA event in Auckland with a back injury.

The 22-year-old has been practising in Melbourne but will go into the major having not played competitively since November's Billie Jean King Cup.

Raducanu has drawn criticism for the way she has approached her career, either for not being robust enough, chopping and changing coaches or her lucrative sponsorship deals.

It does feel, however, that 2025 is the year where Raducanu needs to kick on. A strong run in Melbourne would be a fantastic platform to build from.

Zheng Qinwen recovered from a "stupid mistake" to begin her Australian Open bid with a straight-set win on a rain-disrupted first day in Melbourne.

Chinese fifth seed Zheng, beaten by Aryna Sabalenka in last year's final, won 7-6 (7-3) 6-1 against Romanian qualifier Anca Todoni under the roof on Rod Laver Arena.

The Olympic gold medallist served for the opening set at 5-4 40-0, but could not take any of her three set points.

Todoni, 20, had never beaten a top-50 opponent and had the chance to move halfway to a shock win after creating three set points on Zheng's serve at 6-5.

But she could not convert and Zheng, 22, held before stepping up a gear in the tie-break.

The second set was more straightforward as Zheng, backed as usual by a huge number of Chinese fans, broke early before cruising through to victory.

"The first set is always not easy, especially because I was doing stupid mistakes - I don't know what happened there," she said.

"But I am happy to get through."

On expectations rising after winning the Olympic title, she added: "Of course there starts to be more pressure but [the fans] are pushing me to become a better person and better athlete.

"I like to play with pressure. Like what Billie Jean King says - pressure is a privilege. I love this sentence.

"Let's keep going and playing with pressure."

While Zheng was able to complete her match indoors, a heavy thunderstorm caused play on the outdoor courts to be suspended until 17:00 local time (06:00 GMT).

The first day of the Australian Open has been disrupted by heavy rain and thunderstorms in Melbourne.

Matches at the season-opening Grand Slam tournament started as scheduled at 11:00 local time (00:00 GMT) on Sunday.

But players on the outer courts were forced off about an hour later.

Play will not resume at Melbourne Park until at least 17:00 (06:00 GMT).

The wet weather meant only the matches scheduled on Rod Laver Arena, Margaret Court Arena and John Cain Arena - all of which have a roof - could be played.

Three matches had been completed by 15:00 (04:00 GMT).

Chinese fifth seed Zheng Qinwen, last year's beaten finalist, and teenage Russian 14th seed Mirra Andreeva won in the women's singles.

French 20th seed Arthur Fils secured victory in the men's first round.

Sonay Kartal, who is the only Briton in action on Sunday, was among the players whose matches were delayed.

The British number three was due to start her match against Spain's Jessica Bouzas Maneiro at 14:00 (03:00).

These sides have produced some classic encounters through the years, but Saturday's meeting - their first since 2019 - was for the most part a scrappy affair, with a raft of handling errors reflecting the tricky conditions.

The first half delivered just three penalties; two for Lozowski and one from Jack Crowley, who was in the thick of the action during the opening 40 minutes.

Having earlier spilled a high ball and had a kick charged down that brought Saracens close to the Munster try-line, the Ireland fly-half's handling cost him the chance to score a stunning try.

Spotting a gap in the visitors' defence, Crowley chipped the kick through a sea of Saracens bodies and another over Liam Williams' head before dropping the ball as he bore down on the line.

In the second half, Elliot Daly moved Saracens 9-3 in front, but after both sides failed to put more points on the board with missed kicks from Crowley and Fergus Burke, Munster pulled clear with a devastating one-two punch.

First, Bleuler dove over from close range on the hour mark after Gavin Coombes drove Munster to the Saracens line, with Crowley's conversion edging the hosts ahead for the first time.

Five minutes later, Thomond Park erupted when Hodnett broke through to finish off a fine move from injury-hit Munster, who were without Peter O'Mahony and Craig Casey among others.

Replacement back row Hodnett, who scored two tries in the loss at Castres, survived a last-ditch Williams tap-tackle to finish and open up a 17-9 lead.

Saracens were not done, though. After Lozowski's third penalty brought Saracens to within a score, the visitors pushed for a dramatic late try only for a promising move to break down when Wales international Williams spilled the ball metres short of the line.

The result leaves the battle for second spot - and the home knockout tie that goes with it - finely poised going into the pool round's climax next week.
