Top stars Eugenie Bouchard, Ana Ivanovic, Agnieszka Radwanska and Caroline Wozniacki have all qualified for the WTA Finals in Singapore.

The quartet will join Simona Halep, Petra Kvitova, Maria Sharapova and defending champion Serena Williams as the top eight players in the world to compete at the Sports Hub from October 17-26.

"The year-long competition on the Road to Singapore has been intense and exciting for our fans," said WTA Chairman and CEO Stacey Allaster.

"With a combination of young rising stars and established superstars competing for the coveted Billie Jean King Trophy, every match will be like a Grand Slam final."

Bouchard has qualified after rising to the world ranking of No. 7 on the back of winning her first career WTA title at the Nurnberger Cup and impressive Grand Slam results. The 20-year-old Canadian made her career-first Grand Slam final appearance at Wimbledon and reached the semi-finals at the Australian Open and Roland Garros.

Ivanovic has secured four titles this season, including triumphs at the ASB Classic (Auckland), Abierto Monterrey, Aegon Classic (Birmingham) and Toray Pan Pacific Open (Tokyo). The Serb is making her first appearance at the WTA Finals since her debut season in 2008.

Radwanska captured a title at the Rogers Cup (Montreal), a finals appearance at Indian Wells and made the semi-finals at the Australian Open, Qatar Total Open and Mutua Madrid Open. The 25-year-old Pole play at the WTA Finals for the sixth time in her career (2008-09, 2011-14).

World No.8 Wozniacki has enjoyed a strong second half of the season that saw the Dane win her 22nd career title at the TEB BNP Paribas Istanbul Cup and finished as runner-up at the US Open and Toray Pan Pacific Open in Tokyo. The former World No.1 will be at the WTA Finals for the fourth time.

The singles draw ceremony for the WTA Finals will be held on Oct 18 in Singapore.
