Rory McIlroy’s tennis star girlfriend Caroline Wozniacki insists the World No. 1 ranked gofer was  “very comfortable” with his new Nike clubs and hopes to disprove doubters at this week’s WGC – Accenture Match-Play Championship in Arizona.

While McIlroy will be in Arizona, Wozniacki is in Hong Kong for the BNP Paribas Tennis Showdown.

And the Danish tennis ace says her double Major winning boyfriend will rid Nike management of a month-long crimson red face and return to form in Wednesday’s starting $USA 8.75m event against first round opponent, Shane Lowry.

“Rory likes his new clubs and is very comfortable with them,” said Wozniacki.

“He’s going to play a tournament this week and hopefully he’s going to do well.”

And while Wozniacki defended McIlroy, the current World No. 10 ranked tennis star faced continuing questions as to whether she and McIlroy were engaged despite arriving at the Brisbane International in late December wearing what looked like an engagement ring.

“No we’re not engaged — but everything is good thank you and everything is going well,” she said.

“We do a lot of training together and he likes the gym, he goes every day. We often hit the gym together.

“You can always learn something, and obviously Rory is (world) number one. It gives you a different view in terms of sport and it’s nice to be able to draw from that experience.”

Wozniacki will play China’s world number five Li Na at the exhibition event staring on March 4th in the China Special Administrative Region.
