Garbiñe Muguruza’s sensational run in the women’s singles draw at the French Open may have come to an end in the quarterfinals… But she’s still in the title hunt at Roland Garros.

The 20-year-old half-Spanish-half-Venezuelan tennis player, considered one of the WTA’s rising stars, and her women’s doubles partner Carla Suarez Navarro beat Kveta Peschke and Katarina Srebotnik, the tournament’s No. 4 seeds, 6-4 6-4, in the quarterfinals to advance to the next round.

Peschke and Srebotnik, 2010 French Open finalists and 2011 Wimbledon champions, were the heavy favorites going into the match.

It’s only the third Grand Slam doubles appearance of her young career. Muguruza’s previous best showing in women’s doubles at a Grand Slam was a second round appearance at this year’s Australian Open.

Muguruza and Suarez Navarro will have a tough challenge in Friday’s semifinals. They’ll be facing off against this year’s No. 1 seeds, Taiwan’s Hsieh Su–wei and China’s Peng Shuai.

In the last two years, she’s taken home doubles titles at the Hobart International in 2013 and this year’s Marrakech Grand Prix. She and current partner Suarez Navarro were the runners-up at last month’s Madrid Open.
