Caroline Wozniacki has defeated American tennis star, Venus Williams 6-4, 6-4 to win the biggest title of her career at the WTA Finals on Sunday.
The Dane, a former world number one, but who has never won a Grand Slam title, swept Serena’s Sister at the Singapore Indoor Stadium.
The new champion’s aggressive approach proved too much for the veteran American opponent after the sixth seed edged a tight first set. Wozniacki then charged into a 5-0 lead in the second before surviving a late fightback.
It marked the 27-year-old’s first victory over her opponent in eight attempts stretching back to 2007.
“It feels amazing, I can’t believe I am here as the winner,” Wozniacki told BT Sport.
“Venus Williams is a great champion and she made it very, very difficult for me.
“This is my biggest title to date.”
Wozniacki has lost US Open finals in 2009 and 2014 and also reached the last-four stage of the Australian Open in 2011.
She was also defeated by Belgium’s Kim Clijsters in the final of the World Tour Finals in 2010.
Romania’s Simona Halep, meanwhile, will end the season as world number one despite failing to make it out of the group stage in Singapore.
