Australian Ash Barty didn't expect she'd be a quarter-finalist at the French Open.
The 23-year-old powered into her maiden French Open quarter-final after a gritty 6-3, 3-6, 6-0 win against American Sofia Kenin on Monday.
"I didn't expect it at the start of the week but I've been preparing well, playing well and enjoying myself," Barty told Eurosport after her victory.
Rod Laver, who was sitting courtside at Barty's match, had no doubts the Queenslander can continue to perform at Roland Garros.
"It's amazing what she has accomplished here," he told media.
"A couple of years back, she was a good doubles player and played some attractive singles but something happened. She says, 'I know how to win matches now', and that's what Barty has accomplished this year.
"It's more confidence than anything else. With confidence, you can make anything happen."
Barty took the first set with relative ease but a late fightback from Kenin could have been a warning sign of what was to come in the second.
However, despite dropping the second, the world No.8 bounced back in style in the third and showed that a blimp in the road didn't break her mental game.
It will be Barty's second consecutive grand slam quarter-final after reaching the same stage at the Australian Open earlier this year.
She will be looking to become the first Australian French Open singles champion since Margaret Court in 1973.
In the last 46 years, only four Australian women have made the quarter-finals at Roland Garros including Wendy Turnbull, Dianne Fromholtz and Sam Stosur.
Barty now faces Madison Keys on Wednesday.
