The 24-year-old from Sokolov is used to delivering unexpectedly in Paris … and elsewhere. Five years ago, the left-hander, then just 19 years old and unseeded again, became the youngest woman in 10 years to reach a Grand Slam singles final when she played for the title at Roland-Garros, where she was beaten by Ash Barty.
Injuries, including two surgeries on her wrist, took her out for chunks of time over the next four years, but never fully prevented her from reaching big milestones: in addition to winning at SW19 last summer, she also won the silver medal at the last Olympics in Tokyo.
And repeatedly delivering on the game's grandest stages has, slowly but surely, erased some of the low-key left-hander's self-doubt.
“I think the most important thing … for me, for my head, [is] just to know that I can keep up with these players, just play close matches with them and actually win the match,” she said after beating Sabalenka in Stuttgart.
“So I think it's mostly for me just to know, 'You can do it.'”
Whatever her result on Court Philippe-Chatrier on Tuesday, this surprise package is quickly becoming a sure thing.
