World No. 1 Caroline Wozniacki and her father, Piotr, have ended their coaching relationship, Ekstra Bladet reports. The father and daughter apparently discussed her moving in another direction after Dominika Cibulkova upset Wozniacki at Wimbledon. The Wozniackis are said to have hired a new private coach to travel with Caroline, but he/she has yet to come on board, so Piotr went with Caroline to Toronto and Cincinnati.
Wozniacki fell in the opening round of both tournament, to Roberta Vinci in Toronto and to Christina McHale in Cincinnati. Piotr was heard yelling at the slumping Caroline when he came on court during her loss to McHale.
The identity of the new coach is so far unknown but is said to be a former touring pro.
Wozniacki's agent, Lagardere's John Tobias, confirmed to TENNIS.com that Piotr is stepping back, but said that no definitive hire of a new coach has been made yet.
Wozniacki has also worked with adidas Player Development coach Sven Groenefeld. Piotr Wozniacki, a former soccer player in Denmark, is said to have encouraged his daughter to try someone else out. Wozniacki, who has yet to win a Grand Slam, has been criticized for playing too defensively.
"We've heard from morning to night how Caroline should play," Piotr told the newspaper. "So now she tries something else. It is intended that she should be a very aggressive player. But as you can see, she cannot win matches right now, because she does not know how she should play. But whatever, I'm Caroline's father, and I will always support her."
She is scheduled to play in New Haven next week.
