SINGAPORE - French Open champion Jelena Ostapenko has become the seventh player to book her spot at the season-ending BNP Paribas WTA Finals Singapore presented by SC Global.

The 20-year-old Latvian joins Garbine Muguruza, Simona Halep, Karolina Pliskova, Elina Svitolina, Venus Williams and Caroline Wozniacki in the elite eight-woman singles field.

Ostapenko secured her ticket to the WTA Finals on Wednesday (Oct 4) after Briton Johanna Konta - currently holding the eighth and final qualification spot in the Porsche Race to Singapore - withdrew from next week's Prudential Hong Kong Tennis Open on Tuesday.

Ostapenko defeated Australian Samantha Stosur 6-3, 7-5 to reach the third round of the China Open in Beijing on Wednesday.

The top eight singles players will qualify for the Oct 22-29 event at the Singapore Indoor Stadium.

Ostapenko is set to make her debut at the WTA Finals following a season highlighted by winning her first Grand Slam title at Roland Garros in June.

"I'm extremely happy to qualify for my very first WTA Finals," said Ostapenko in a press release issued by the WTA. "I've had a great season and hope I can continue to play my best tennis in front of all the fans in Singapore."

She started the year ranked 44th in the WTA rankings but she is now at a career-high No. 8.

Despite losing in the first round of the China Open, Konta can still complete the WTA Finals singles field this week if either Australian Ashleigh Barty or Russian Elena Vesnina fails to win the title and France's Caroline Garcia falls before the semi-finals in Beijing.

Last year, Konta was denied her WTA Finals debut a day before the competition began, when Svetlana Kuznetsova won the Kremlin Cup in Moscow.
