Tennis: Goodbye girl Pennetta, Kerber join WTA Finals lineup

Flavia Pennetta of Italy reacts after losing a point against Anastasia Pavlyuchenkova of Russia during their women's singles third round match at the China Open tennis tournament in Beijing on October 8, 2015.

PARIS - US Open champion Flavia Pennetta and Germany's Angelique Kerber qualified for the eight-woman season-ending WTA Finals on Wednesday, leaving just one place to decide.

The pair join Simona Halep, Garbine Muguruza, Maria Sharapova, Petra Kvitova and Agnieszka Radwanska in the October 23-November 1 tournament in Singapore.

It is a competition which will be missing world number one Serena Williams who has shut down her season.

"Qualifying for the WTA Finals in Singapore is a dream come true and the perfect way to end to an amazing season for me," said Pennetta who will retire from the sport after the event.

"It will also be a wonderful way for me to say to say goodbye to tennis - it's a spectacular stage to bow out on. Having won the WTA Finals before in doubles, I can't wait to make my debut in singles."
