Barty claimed the French Open title to end a 46-year drought at the event, and then snatched the top rung of the rankings from Naomi Osaka with a win at Birmingham.

She’s now on a 12-game winning streak and is hoping to go deep at Wimbledon, where she had previously won the Junior Grand Slam crown.

An arm injury forced Barty out of the Eastbourne tournament and she will first step onto court with her World No. 1 ranking at Wimbledon, which starts on July 1.

But Former World No. 1 and 18-time Grand Slam Champion Chris Evert said a taxing month may have taken a lot out of the 23-year-old Australian.

The US champion said Barty has obviously got the game to win the title but her recent success may have taken its toll.

“She’s got a great grass court game — I think she loves the grass,” the three-time Wimbledon champion and ESPN expert said. “I think it’s interesting that her parents were scheduled to come over for the grass court season, not for the clay court season. Look what happened.

“I think it would be like a herculean effort if she won Wimbledon — to have won the French, to have won the warm-up tournament (Birmingham) … and then when she won that, she became No. 1. At some point it’s got to be overwhelming, and she’s a human being.

“I mean, it would be so impressive if she won Wimbledon. She has the game. She has the athleticism, the variety. I just kind of wonder when the tank is going to start to get a little bit empty, both physically and emotionally. So it’s going to be tough.”

Evert also named Serena Williams, who is chasing her record breaking 24th Grand Slam title, while she also named homegrown talent Johanna Konta as a hope.

Aussie legends Rod Laver and Margaret Court have both backed Barty to go back-to-back and take out Wimbledon.

Laver said the Aussie start has the “mental strength and all court game” to win the most prestigious Grand Slam.

“The grass won’t cause her any issues at all, in fact she will enjoy it,” he said, as reported in The Herald Sun.

“As I was at Roland Garros, I’ll be court side to watch her progress and nothing would give me greater pleasure, than to be there to see her triumph on Saturday week.”

Court, who was the last Australian French Open champion in 1973 before Barty snapped the drought, told SEN’s The Bucket List Barty is bucking the trend of “robotic” modern players.

“I always feel if that type of game came back in again we would have a lot more champions,” Court said.

“(Barty) has a variety. If something is not working, she has something to fall back on. She can hit through the ball, she can slice the ball. She has played a lot of doubles. She has a good volley, a good serve and a good all round game but she can also change her game which a lot of girls can’t do.

“I think it’s such an asset for her to do that. It’s sort of the 60s and 70s game and you can use that on any surface.”

Barty has spoken about her career-threatening mental health battle ahead of Wimbledon, where she is the first Australian woman to headline the Wimbledon draw since Margaret Court in 1973.

It was less than five years ago that Barty quit tennis while struggling to cope with the suffocating pressure of being touted the sport’s next big thing after winning the Wimbledon junior crown at just 15.

Depressingly homesick, Barty packed it in after a first round US Open defeat.

“We went through ebbs and flows in that year in 2014,” Barty said. “I’m not going to go into details of how I felt and what I had to go through, but there was a point when I think I knew I had to stop and, when I made the decision, it was easy.

“Everyone is different, everyone is unique. I can’t sit here and tell people how they should figure out their way through their life. It’s their decision.

“For me, it was just being aware of my mental health. Having a discussion with people was the best thing that came out of it.”

Barty admitted she wouldn’t be where she is right now had she not taken time out and played professional cricket.
