Serbian teen Olga Danilovic stunned top-seeded Julia Georges 6-3, 6-3 to reach the semifinals of the Moscow River Cup on Friday.
Danilovic, 17, is in the tournament as a lucky loser and reaches her first-ever WTA semifinal after beating the world’s No. 10 player.
“Every win here is important, especially since I played with one of the top players in the world right now,” Danilovic said afterward. “It’s an amazing feeling, an amazing win.”
Unseeded Slovenian Tamara Zidansek, who stunned No. 2 seed Daria Kasatkina on Thursday, also advanced to her first career semifinal by beating Laura Siegemund, of Germany, 6-3, 6-4.
Another 17-year-old, Russian wild-card Anastasia Potapova, also advanced on Friday, rallying after dropping the first set to knock off fellow Russian Valentyna Ivakhnenko 1-6, 6-3, 6-2. She’ll face Zidansek in the semifinal.
Friday’s expected marquee match never got off the ground as third-seeded Anastasija Sevastova pulled out of the tournament ahead of her showdown with No. 5 seed Aliaksandra Sasnovich of Belarus.
Sasnovich will face Danilovic in Saturday’s other semifinal.
Unseeded Lin Zhu stunned top-seeded Shuai Zhang 7-6 (3), 4-6, 6-1 to reach the semifinals in Nanchang, China.
Zhu, of China, will face another countrywoman in the semifinal in sixth-seeded Saisai Zheng, a 6-3, 6-4 winner over Fang Ying Xun.
No. 2 seed Qiang Wang also advanced with a 6-3, 6-0 win over Fangzhou Liu to set up a showdown with third-seeded Magda Linette of Poland.
Linette held off unseeded En Shuo Liang, of Taiwan, 6-3, 4-6, 6-2.
