But how can a player who is only 23 be called slow?
"I'm nearly scared to say it but it's now 48 years ago I won my first Slam there, too".
Ashleigh Barty hated her first trip to Paris but 10 years later, after one of the more remarkable tennis journeys, she woke up in the French capital on Sunday as queen of Roland Garros.
"Because she won junior Wimbledon, everyone assumed grass would be her best surface". A tennis player rarely experienced IQ certification your compatriot Samantha Stosur agreed at the 2011 US Open, the last Australian victor of a Grand Slam tournament. In this game you can't sit still and she knows that.
Barty played for the Brisbane Heat cricket team in the Women's Big Bash League four years ago, playing nine matches with a top score of 39.
Naturally, Barty did return to tennis. She is the first Australian woman to win a major title since Samantha Stosur won the 2011 US Open, and the first to win Roland Garros since Margaret Court in 1973.
Barty had never previously made it past the second round of the French Open.
There was no doubt that the soon-to-be world No 2 always had it in her.
"She has been close".
The Australian has one of the most versatile game styles on tour.
Cracking a stiff-armed, two-handed backhand, in the manner of Jim Courier, Barty was able to counter Vondrousova's attempts to pull her wide with her loopy left-handed backhand, and the Czech rapidly ran out of ideas.
All traceable, in some way, to her time away from the sport. "So I think the time away was the best thing for her".
Barty also acknowledged former Australian tennis champion Evonne Goolagong Cawley for inspiring her to succeed. It has made a huge difference to her mentality, an aspect she has never been shy to discuss. Of course it was to play tennis.
She used a very Anglo-Saxon expletive as match point landed then turned, arms aloft, to salute her box and sank on her haunches for a brief moment of contemplation. "It's just been an unbelievable journey that we've had over the last few years", Barty said. She had also had moderate success in the singles during this time, but while her doubles successes continued into the next year, she struggled in the singles - physically, and most importantly, mentally.
Meanwhile, the second men's semi-final was completed on Saturday.
But that is how Barty got to the final in the first place. But with grit and her all-court game, she clawed her way back to beat the 17-year-old, who had stunned defending champion Simona Halep, 6-7 (4), 6-3, 6-3.
And that's with, arguably, her best surface coming around the corner: grass. Now the number-one ranking is well within her reach, with Naomi Osaka only holding a narrow lead at the summit, and Barty has the Japanese star in her sights.
"You only have to look at the age of the girls who got through here". She moved back in with her family to Ipswich in the North of Australia, went fishing or had a few lessons with a coach.
Barty, a Wimbledon junior victor, wasn't very fond of the surface.
"What a wonderful result for Australia and how exciting that another Aboriginal has won at the French Open".
"Obviously I love the grass-court season", Barty said. By the end of that season, she had reached 272. Next year, she would prove her huge prowess at the doubles.
Ashleigh Barty, who just won her first Grand Slam tennis title in French Open, said she witnessed an incredible period of her life when she was a cricketer.Barty took a break from her tennis career in 2014 and a year later she played in the Women's Big Bash League (WBBL) for Brisbane Heat.
The teen, less experienced than Barty on the Grand Slam stage perhaps, just did not seem to find her footing early on.
