French Open champion Ostapenko makes season-ending WTA Finals

The Latvian, who will make her first appearance in the Oct. 22-29 event, joins Garbine Muguruza, Simona Halep, Karolina Pliskova, Elina Svitolina, Venus Williams and Caroline Wozniacki.

"I'm extremely happy to qualify for my very first WTA Finals," the 20-year-old said on the WTA website (www.wtatennis.com). "I've had a great season and hope I can continue to play my best tennis in front of all the fans in Singapore."

Ostapenko, who is through to the third round of the China Open in Beijing, won the second of her two career titles at the Korea Open in Seoul last month.

The top eight singles players at the $7 million prize money event will face off in a round-robin format for the Billie Jean King Trophy.

One place is still available for the showpiece with Britain's Johanna Konta currently holding eighth place in the WTA Race to Singapore standings.

Konta, a reserve last year, has suffered five straight defeats, however, and several players could still overhaul her. (Reporting by Shrivathsa Sridhar in Bengaluru and Martyn Herman; Editing by Christian Radnedge)
