French wild card Loïs Boisson shocks Mirra Andreeva to reach Roland Garros semifinals

Loïs Boisson’s Roland Garros fairytale continued on Wednesday, the No. 361st ranked French wild card stunning Mirra Andreeva, 7-6 (6), 6-3 to reach the semifinals.

Boisson caused the biggest upset of the women’s event when she shocked No. 3 seed Jessica Pegula to reach the quarterfinals; she backed up that win by grounding the No. 6-se22-eded teenager in two hours and eight minutes beneath the Court Philippe-Chatrier stadium roof.

Boisson had never faced anyone ranked inside the Top 50 prior to Roland Garros, her previously-highest ranked opponent being world No. 60 Moyuka Uchijima earlier this year at a WTA 250 in Rouen. The 22-year-old needed a wild card to get into the main draw, having missed her planned debut last year due to a torn ACL. She had gone viral at that tournament after opponent Harriet Dart made disparaging comments about her during their match, a moment Boisson later took in stride on social media.

She began the week with a three-set win over No. 24 seed Elise Mertens and later won another three-setter against fellow wild card Elsa Jacquemot to reach the second week. Once there, she rallied from a set down to defeat Pegula to book the biggest match of her career against Andreeva.

Though she’s four years younger than Boisson, Andreeva came into their quarterfinal with considerably more experience, having reached the semifinals of this tournament last June. She began 2025 with back-to-back WTA 1000 titles in Dubai and Indian Wells, vaulting into the Top 10 under esteemed coach Conchita Martinez. She didn’t drop a set through her first four matches, and appeared on course for another seamless victory when she took a 5-3 lead on Boisson to kick off the final last-eight clash of the women’s tournament.

Saving a set point on her serve, Boisson—who, alongside Andreeva, got to warm up alongside world No. 1 Jannik Sinner before their match—broke straight back and shook off losing a marathon 11th game to power through the subsequent tiebreaker, saving one more set point along the way.

A frustrated Andreeva looked to have righted the ship early in the second, racing out to a 3-0 lead. But Boisson soon climbed back into the match, winning the next five games to find herself on the brink of victory.

In anger, Andreeva knocked a ball into the crowd, startling a ball kid behind her, and couldn't reign in her emotions as she served to stay in the match, quickly falling behind 0-30. A forehand into the net handed Boisson three match points, and Boisson took full advantage, forcing a final error off a well-struck forehand to reach the final four in Paris.

Up next for the tournament's Cinderella story will be No. 2 seed Coco Gauff, who roared back from a set down to snap Madison Keys' 11-match Grand Slam winning streak earlier in the afternoon.
