Will turn 22 on
What she’s done since last summer
- Reached the semifinals at tournaments in Abu Dhabi and Istanbul
- Made a Grand Slam doubles quarterfinal at Roland Garros (2020)
- Reached the fourth round of Roland Garros (2021)
- Kostyuk won her first junior Grand Slam title at 14 years old
Kostyuk was the first from her generation to strike it big on the WTA circuit, making it just shy of the second week at the 2018 Australian Open as a 15-year-old. A combination of injuries and expectations stalled the Ukrainian teenager for over two years before she turned heads once more at last year’s US Open, where she took eventual champion Naomi Osaka to three sets.
