Elina Svitolina and Marta Kostyuk face off for the right to become the first Ukrainian women's singles semi-finalist at the French Open since the start of the open era in 1968.
Their showdown is a landmark moment for Ukrainian tennis and brings together two of the most in‑form players on the WTA Tour on the most iconic clay court in the world.
Kostyuk enters with a 16‑match winning streak on clay, including a breakthrough Madrid title last month, where she dismantled Mirra Andreeva in the final.
Her fourth-round victory over four‑time French Open champion Iga Swiatek was arguably even more impressive as she produced 25 winners and six breaks of serve.
Svitolina, meanwhile, has been a model of consistency all season.
Her title in Auckland, a final in Dubai and deep runs in Melbourne, Indian Wells and Stuttgart re‑established her as a top‑tier contender, which she proved again in Rome by winning the Italian Open late last month.
She survived a first‑round scare against Anna Bondar but has since tightened her level, overcoming Belinda Bencic in three sets to reach the last eight.
Seven years older than Kostyuk and with four appearances in Grand Slam semis on her CV, Svitolina has the edge in terms of experience.
However, Kostyuk is full of confidence and knows how to beat Svitolina, having taken the win in their most recent meeting two years ago.

Elina Svitolina v Marta Kostyuk Prediction
Best Bet: Marta Kostyuk -0.5 games handicap @ 5/6
This match feels like it could be the moment Kostyuk steps fully into the elite tier of women's tennis.
She has been knocking on the door for a couple of years at Grand Slam level, but this is her chance to make the last four at a major for the first time.
Her clay‑court level this season has been extraordinary - not just consistent, but assertive, fearless and tactically sharp.
Her victory over Swiatek on Sunday was relatively comfortable in the end as her Polish rival wilted under the pressure for only her third defeat in 46 singles matches at Roland Garros.
That win was the culmination of a month‑long surge in confidence and execution. She is striking the ball heavier, defending smarter and returning with far more aggression than in previous seasons.
Svitolina’s experience is undeniable, but she has shown vulnerability in Paris. Bondar pushed her to a super‑tiebreak and Bencic exposed her slow starts. Against a red‑hot Kostyuk, those lapses could be costly.
The younger Ukrainian’s ability to take time away, step inside the baseline and attack Svitolina's second serve gives her a clear tactical edge.
If she maintains the discipline she showed against Swiatek, she can control the tempo of rallies and force Svitolina into defensive patterns.
Expect long exchanges, plenty of breaks and momentum swings, but Kostyuk's higher ceiling on clay gives her the edge.
Alternative Bet: First set under 9.5 games @ 4/5
Both players tend to start matches with high intensity and heavy physicality. There is no reason to think that Tuesday's tussle will be any different.
But while both players' return games are elite, neither possesses the kind of overwhelming serve that produces quick holds.
The match-up looks likely to produce long rallies and plenty of break-point opportunities, which in turn probably reduces the prospect of a long, drawn-out first set.
And history also points to an opener that could be done and dusted before the 10th game. All five of their previous sets have lasted exactly eight games.

Marta Kostyuk to win

Marta Kostyuk 3+ aces
Pays 6/1
Kostyuk broke serve six times against Swiatek and has averaged over four breaks per match this clay season, while there has been an average of eight service breaks in Svitolina's four matches in Paris this year.
Pushing the total match breaks above eight looks possible in this clash of exceptional returners.
Kostyuk has been serving with more confidence, hitting her spots and mixing in more flat first serves - enough to produce at least three aces across a long match.
If Kostyuk wins, it will likely be through sustained pressure and multiple momentum swings, making this Bet Builder a strong value play.
