"Overall, I am happy with the victory," said Wozniacki, who is currently the world number six. Kerber has won six of her past 10 meetings with Wozniacki, including the April final of the Porsche Tennis Grand Prix in Stuttgart, Germany. Swiss teenager Belinda Bencic edged past former US Open champion Samantha Stosur in a gruelling second-round thriller.
