Marta Kostyuk of Ukraine, who has not lost on the clay courts this season, advanced to the fourth round of the French Open on Friday -- with four-time champion Iga Swiatek her next opponent.

The 15th-seeded Kostyuk won titles on the clay courts in Madrid and Rouen leading up to the French Open. She advanced with a 6-4, 6-3 defeat of Viktorija Golubic of Switzerland.

Swiatek, the third seed, most recently won the title at Roland Garros in Paris in 2024. She defeated Magda Linette 6-4, 6-4 in an all-Polish match on Friday to advance. With the win, she avenged her three-set loss to Linette earlier this year in Miami.

Swiatek has yet to win a tournament on clay this season and has a record of 9-3. Her most recent title, on any surface, came last August in Cincinnati.

Kostyuk had an optimistic tone in her post-match news conference, even though she has lost all three career matchups against Swiatek and hasn't won a set from her.

'I definitely have a different feeling going into this match,' she said. 'Because I feel like last time that I played her in Cincinnati, I lost this match way before it even started, and I don't feel the same this time.'

Swiatek also won the tournament in 2020 before three straight victories from 2022-24 and is 43-3 overall at Roland Garros. Only Chris Evert (seven) and Stefanie Graf (six) have more singles wins in Paris during the Open Era.

Kostyuk knows that history, too.

'She's won this tournament four times. I would love to be the one who is a favorite in this match, but I still don't think it's the case, even though I have this really long streak,' the Ukrainian said. 'But it's not going to ruin my day or ruin my game. I still want to go out and try my best and enjoy. Like, I have never taken a set off her. Even if I win one set in the next match, I'm going to be very happy. That's how I look at it, and I'm excited for this match.'

Other winners Friday were eighth-seeded Mirra Andreeva of Russia, who defeated Czech Marie Bouzkova, the 27th seed, 6-4, 6-2. In the fourth round, she will face Jil Teichmann of Switzerland, who upset 10th-seeded Karolina Muchova of Czechia 6-1, 7-5.

Sorana Cirstea of Romania, the 18th seed, shut out Solana Sierra of Argentina 6-0, 6-0 to set up a fourth-round meeting with Xiyu Wang of China.

Seventh-seeded Elina Svitolina of Ukraine ousted Tamara Korpatsch of Germany 6-2, 6-3. She will play the winner of the late Friday match between 11th-seeded Belinda Bencic of Switzerland and Peyton Stearns.
