Australian Open 2024 results: Jack Draper, Cameron Norrie and Katie Boulter win

Britain’s Jack Draper battled through the Australian Open heat to win his first five-setter – and then threw up at the side of the court after victory.

Draper called for the doctor and had his blood pressure checked before a 6-4 3-6 4-6 6-0 6-2 win against American Marcos Giron in temperatures above 30C.

Earlier, Cameron Norrie showed no sign of any wrist issues as he won 6-4 6-4 6-2 against Peru’s Juan Pablo Varillas.

Katie Boulter also advanced with a 7-5 7-6 (7-1) win over China’s Yuan Yue.

Fellow Britons Emma Raducanu and Dan Evans play later on Tuesday.

Norrie, seeded 19th, Draper and Boulter are the only players from the nation through so far, with Jodie Burrage and Andy Murray having lost on the first two days of the tournament.

When Draper needed medical attention at the end of the second set, and disappeared off court after the first game of the third, it looked to be a familiar tale.

The 22-year-old has been plagued by a host of physical problems and early retirements in his burgeoning career.

Playing in stifling temperatures on the hottest day of the tournament so far, Draper appeared in deep trouble when he trailed by two sets to one.

Instead, he recovered admirably to earn what must rank among his most gratifying victories.

Draper won eight games in a row to turn the match in his favour and managed that, with instructions from his team to try to keep the points short, by using more variety with serve and volleys, slice and drop shots.

In the decider, Draper broke again for 4-2 after outlasting and outthinking Giron in a brilliant exchange on break point.

That left the Briton bent over the side of the court to catch his breath and his physical exertions were illustrated even more starkly when he clinched victory.

After stretching for a forehand winner on his first match point, Draper shook hands with Giron before immediately running over to a courtside bin to be sick.

Before the match, left-hander Norrie had said he was “concerned” by a problem with his left wrist which forced him to pull out of an ATP event in Auckland five days ago.

Norrie, who is Britain’s highest-ranked singles player, is safely through and faces Italian qualifier Giulio Zeppieri next.

After a poor end to last year where he admitted feeling burned out, Norrie is looking to bounce back in 2024 and go beyond the third round in Melbourne for the first time.

After scrapping to save a break point in his first service game, Norrie quickly asserted his authority as he took advantage of Varillas’s poor service game.

Norrie applied heavy pressure as the Peruvian barely landed a first serve, eventually taking a sixth break point for a 3-2 lead which was enough to secure the opening set.

With Varillas’ first-serve percentage down below 45%, Norrie moved a double break up at the start of the second set, allowing for him to drop serve before seeing it out at the second opportunity.

Varillas produced a double fault to hand over another break for 2-1 in the third and Norrie continued to move through the gears nicely.

He took his opponent’s serve for the fifth time before ending Varillas’ late resistance by taking his third match point in what was a pleasing opening performance.

“I think I did the basics well. I served well in the big moments and I think I won a lot of points on my first serve when I did make them,” Norrie said.

“I didn’t think I served that well, but I didn’t lose many points on my first serve, which was good to see.”
