Caroline Wozniacki sorry for Nadal’s ‘cramping spasm joke’ at US Open

 Danish tennis ace Caroline Wozniacki has said that she was not making fun of Rafael Nadal when she imitated the Spanish superstar's cramping spasm at the US Open.

"Had a bit of fun last night b4 my press conference. Hope it was not taken the wrong way. I have the upmost respect and admiration of Rafa !," the Dane said on her Twitter account, the Sydney Morning Herald reports.

Nadal slid to the floor in agony during a news conference after his fourth-round win over David Nalbandian on Sunday, slipping slowly off his chair and disappearing behind a table.           

The episode was filmed and had become a huge internet hit.

On Monday, World No.1 Wozniacki laughed off the incident in the same conference room after her marathon last-16 victory over Svetlana Kuznetsova.
