Jack Draper has been told that he must stay on top of a huge problem that could derail his career. The British No. 1 enjoyed the best fortnight of his career in Indian Wells, winning his first Masters 1000 title and breaking the world’s top-10. It was a fitting reward for the work Draper has put in to overcome his physical issues.

The 23-year-old previously raised question marks about his fitness when he became dizzy and vomited during some Grand Slam matches last year. However, renowned tennis coach Patrick Mouratoglou has now shared his own theory about Draper’s health woes, also claiming that “all of Britain” was watching and expecting him to keep winning.

Draper has already faced plenty of injury layoffs in his young career, dealing with issues in his abdomen, elbow and hip. He’s also retired from his share of matches, battling cramps and dizzy spells at tournaments staged in hotter climates, like the Australian Open.

It led former players and coaches like Andy Roddick and Mark Petchey to question his fitness, urging the Brit to find a training base in a warm country. But, in 2025, the 23-year-old has proven that he has what it takes to survive long, gruelling matches and go deep in tournaments.

Draper won three five-set matches in a row Down Under, then reached the Qatar Open final by coming through some tight three-setters before lifting the biggest title of his career in Indian Wells.

With the questions around his stamina and athleticism now all but gone, French tennis coach Mouratoglou has suggested that the problems were all mental – though he has warned Draper that he is still going to be more injury-prone than his smaller rivals.

“When you see a young player struggling physically like Jack was, that can sometimes be mental more than physical,” Naomi Osaka’s current coach told Tennis365.

“The cramps Jack had and I also remember him throwing up during some matches. This is probably mental and it takes time to find a way to understand this and to control it.”

According to Mouratoglou, Draper also has more weight on his shoulders as a British tennis player. He added: “Sometimes you go through moments at the start of your career when you really start to break through that there are so many hopes and expectations on his shoulders. Not just from the player, but also from everyone around him.

“Also, all of Britain wants him to win as well, I guess. That can be very difficult to handle. What I believe about Jack is he is very ambitious and extremely courageous. He has the right mentality to win, but he had to understand how to control that on court.”

While the vomiting issues appear to be behind him, Mouratoglou has urged the 6’4” Draper to work on injury prevention or risk having his career derailed like other big guys.

“He’s tall, he’s strong and you need to pay even more attention to the bigger guys,” he continued.

“Look at someone like Juan Martin del Potro and he had a lot of injury problems. This is because it is tough for the bigger guys to avoid injury and this is an issue Jack needs to be on top of because it can stop him from going to the very top.

“He’s a great player. We knew that before he won Indian Wells. I’m not surprised he is now in the top ten and there is much more to come.”

Draper has already assembled a top team to help him get a hold of any physical troubles. As well as his tennis coach James Trotman, the world No. 7 has been working with physiotherapist Shane Annun and fitness coach Matt Little – two former members of Andy Murray’s camp.
