Elena Rybakina is through to the US Open fourth round for the first time, routing Emma Raducanu 6-1, 6-2 on Friday.
What sparked her resurgence?
The No. 9 seed credits her improved health and stability in her coaching box, with Stefano Vukov back on her team after an eight-month ban.
Elena Rybakina tried a new coach, Goran Ivanisevic, during the Australian Open, but it didn't work out.
Why is Vukov's return significant?
Vukov's return has brought good communication and support to Rybakina's team, which she believes is essential for her success.
The WTA had banned Vukov for breaking the Code of Conduct, but he was cleared to return at the start of August.
What's next for Elena Rybakina?
Rybakina will face Marketa Vondrousova, the 2023 Wimbledon winner, on Sunday, looking to continue her strong run.
She has reached the semifinals in Washington, Montreal, and Cincinnati, including a win over world No. 1 Aryna Sabalenka.
Elena Rybakina had struggled with insomnia and health issues in 2023 and 2024, but says she's now back to full health.
The 26-year-old, born in Russia and representing Kazakhstan, is eager to move forward and build on her recent success.
Rybakina's win over Raducanu marked her first time reaching the fourth round at the US Open without dropping a set.
She's looking to turn the page after a turbulent stretch over the past two years and regain her form.
Elena Rybakina's resurgence is a significant development in the tennis world, with the 2022 Wimbledon champion back in contention.
