<p>It leaves world number one Aryna Sabalenka as favourite to claim her first title in Paris, though ‌Kostyuk will be one to watch as ⁠she builds the momentum that ‌has helped her sparkle on clay this season.</p><p><strong>"I'm still in shock," Kostyuk ​said in an on-court interview.</strong></p><p><strong>"I feel like I've given myself more space to just create something, to ​challenge my opponents. I woke up in the morning and all I thought was 'what an unbelievable day I have to live ⁠today ... there's nothing I ​could do other than this'.</strong></p><p><strong>"I try not to focus at all on winning and losing, because I'm not playing tennis to win. I'm playing tennis because I love it. I want to ‌connect to people, I want to feel this energy ... make people happy and unite people."</strong></p><p>There was little to separate the ‌duo in the early ⁠exchanges as ‌they twice traded breaks, before Kostyuk came ​up with a tight hold in the 11th game ​and raised her level at the end to claim the opening ⁠set with ​a backhand crosscourt winner.</p><p>It was the first time that Kostyuk had taken a set off the third-seeded ‌Pole after three straight defeats in their previous meetings, and she sensed a big upset when she went ahead 3-1 in the next set after a battling effort.</p><p>The Rouen and Madrid champion held her nerve from there ‌to take her record on ​clay this season to 15-0, and ‌book a meeting with seventh-seeded Ukrainian Elina Svitolina or 11th-seeded Swiss Belinda Bencic in the next round of Roland Garros.</p><p>Check out all the match stats with Flashscore.</p>
