Two quarterfinals from the bottom half decide the semifinal places on Tuesday, and both carry a charge beyond the scoreline. Elina Svitolina and Marta Kostyuk meet in an all-Ukrainian last-eight tie that already guarantees the country a semifinalist, two unbeaten streaks running straight into one another. Eighth seed Mirra Andreeva, the tour's win leader, takes on Sorana Cirstea, whose farewell season has produced the most unlikely deep run of the fortnight.
Svitolina and Kostyuk collide with the country guaranteed a semifinalist
The all-Ukrainian quarterfinal pits two win streaks against each other, and ensures one of them survives into the last four. Svitolina arrives on 10 straight, the run built on her Rome title - where she beat Andreeva, Gauff and Rybakina back to back - and four wins in Paris, the last two recovered from a set down against Anna Bondar and Belinda Bencic. She is 32-7 in 2026. Kostyuk's streak is longer and unbroken on the surface: 16 matches in a row, 15 of them on clay this season, the only player left in the draw yet to lose on it, with titles in Rouen and Madrid already banked. She reaches her first Paris quarterfinal having ended Iga Swiatek's run of last-eight appearances at every French Open since 2019, beating the four-time champion on her 25th birthday for a first win over her in four attempts after losing the previous three in straight sets. Her earlier rounds carried more strain - a three-set grind past Katie Volynets - but the level against Swiatek was a different thing entirely. On clay this season the rate stats are tight nearly everywhere, with the gaps that exist favouring Kostyuk on return: she wins 58.6% of her return games to Svitolina's 44.1%, 47.2% of first-serve return points to 39.1%, and converts 50.3% of break points to 46.2%. Svitolina's one clear edge is break-point defence, where she saves 72.7% to Kostyuk's 62.3%, the survival rate that has defined her game for a decade. Serve holds and first-serve points are near-even. The head-to-head is level at 1-1, Kostyuk taking the most recent meeting in Toronto in 2024.
Andreeva and Cirstea meet across a generation
The day's other quarterfinal sets the tour's youngest deep threat against one of its most compelling late-career stories. Mirra Andreeva carries the heaviest workload of wins in the game into this one - a tour-leading 33 in 2026 and a 19-3 clay record, also the most clay wins on tour - a year on from the quarterfinal here she lost as favourite to Lois Boisson. Her route to the last eight has been close to untroubled: she dropped just one set, to Marina Bassols, and never trailed on the scoreboard in dispatching Jil Teichmann 6-3 6-2. Cirstea, 36 and playing what she has said will be her final season, is enjoying the best clay tennis of her career, 14-3 on the surface with a Rome semifinal in which she beat Sabalenka, and she has reached the quarterfinals having dropped only seven games across her first three matches, a 6-0 6-0 win over Solana Sierra among them, before holding off qualifier Xinyu Wang 6-3 7-6(4). The achievement carries real historical weight: the 17-year gap between her first Roland Garros quarterfinal in 2009 and this one is the longest between a woman's first and second quarterfinal at a single major in the Open Era, and at 36 she is the third-oldest woman to reach the Paris last eight in that span. On the radar the rate stats lean marginally Cirstea's way - she wins 70.9% of first-serve points to Andreeva's 67.6%, 51.9% of second-serve points to 49.8%, and edges the return-games count 45.7% to 41.7% - while Andreeva's clear edges are serve accuracy (62.6% to 58.8%), break-point defence (59.7% to 51.7%) and tiebreaks, where she has won 83.3% on clay this season to Cirstea's 71.4%. Break-point conversion is near-even at 50.0% to 48.1%. They met once, on Linz clay earlier this year, Andreeva winning 7-6(4) 4-6 6-2.
A Ukrainian is guaranteed a place in the semifinals; the other will be decided between a 19-year-old leading the tour and a 36-year-old in the last weeks of her career.
