The line-up also features St. Petersburg Trophy winner Kristina Mladenovic, Russian Anastasia Pavlyuchenkova, who has won three titles this year, and Indian Wells champion Elena Vesnina.

"This signature event showcases top players along with up and coming stars, all joining together and celebrating their successes of the 2017 WTA season," WTA CEO and Chairman Steve Simon said.

The WTA Elite is a season-ending event that features both singles and doubles competitions. The 12 highest ranked women that did not qualify for the WTA Finals compete in the singles tournament for a total prize money of over $2.2 million.

Chinese number one Peng Shuai, who was beaten by Russian Maria Sharapova in the semi-finals of the Tianjin Open, was handed the singles wild card for the tournament.
