The American tennis player Cori Gauff , 15, surpassed this Friday (7-6 (7/1), 6-4) in the quarterfinals of the Linz tournament to the Dutch Kiki Bertens , first favorite, and became the Younger woman to reach a semifinal in a WTA tournament since Czech Nicole Vaidisova lifted the Tashkent tournament in 2004.

After winning the first set in the tiebreaker, Gauff only needed a break to finish the game in 97 minutes and seal his first victory over a Top Ten player. However, Gauff did not have time to think about his achievement and quickly focused on the duties he would have to do when he arrived at the hotel.

"I have just left the field, so I have not thought about the semifinal," said the teenager, who will meet Germany's Andrea Petkovic in the semifinals. "I am thinking about the duties I have to do tonight. I still don't know what it is. I am studying the typical things: Mathematics, English, History ... I don't know what I have to do today," he said.

The other semifinal will oppose Russian Ekaterina Alexandrova against Latvian Jelena Ostapenko , winner of Roland Garros in 2017.

Gauff rose to fame this year when she became the youngest player to qualify for Wimbledon's main draw in the Open Era. In the London grass he reached the fourth round, leaving Venus Williams on the road.

The American will become the only player under 18 in the top 100 when the rankings are updated on Monday. He will also play the doubles semifinals in Linz, along with also American Caty McNally, 17.
