Paris: Wimbledon runner-up Eugenie Bouchard, Poland's Agnieszka Radwanska, US Open finalist Caroline Wozniacki and former French Open champion Ana Ivanovic have wrapped up the last four spots at the season-ending WTA Finals in Singapore.
The elite eight-player field for the October 20 to 26 showpiece became clear when Angelique Kerber and Ekaterina Makarova both lost their third round matches in Beijing on Thursday.
Bouchard, Radwanska, Wozniacki and Ivanovic join Serena Williams, Maria Sharapova, Simona Halep and Petra Kvitova at the WTA Finals which are being staged in Singapore for the first time.
"I'm excited to compete in my first WTA Finals," Bouchard said. "The fans in Singapore were so enthusiastic when I visited in January for the launch of the Road To Singapore.
"I have worked hard all year on and off the court to qualify."
Ivanovic, who earlier in the day scored her 55th match win of the season -- more than she's ever had in a season before, and more than anyone this year -- said this has been a year-long goal for her.
"It's been my big goal since the beginning of the year," said Ivanovic who saw off Sabine Lisicki in Beijing in her third round clash.
"Everyone really earns a spot there, and I feel like I've been playing so well the whole year. I was working hard towards this."
