Brazilian 14th seed Beatriz Haddad Maia reached her first Grand Slam semi-final by fighting back to stun Tunisia's Ons Jabeur in the French Open last eight.
Haddad Maia, who had never previously reached the third round of a major, recovered to win 3-6 7-6 (7-5) 6-1.
The 27-year-old is the first Brazilian woman to reach a Grand Slam semi-final since Maria Bueno in 1968.
Haddad Maia will play Polish top seed Iga Swiatek or American sixth seed Coco Gauff in Thursday's semi-finals.
Haddad Maia has become known for her ability to come through long tests, including in the Roland Garros fourth round when she outlasted Spain's Sara Sorribes Tormo in an epic lasting almost four hours.
