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.
