Recent Developments
Elina Svitolina and Marta Kostyuk are set for a closely contested opening set when they meet at Roland Garros, with the early stages of the match expected to extend to at least nine games. The all-Ukrainian matchup brings together two players familiar with each other’s rhythms and capable of sustaining long baseline exchanges on clay.
Svitolina’s experience and defensive consistency will be tested by Kostyuk’s aggressive shot-making, particularly in return games. With both players likely to find holds of serve difficult to protect at times, the first set is shaping up as a competitive battle rather than a quick start for either side.
The match, scheduled as part of the 2026 French Open women’s draw, will be decided according to official Grand Slam scoring, with any first-set tiebreak counting as a single game in the total.
