Double celebration for Wozniacki

Caroline Wozniacki paid tribute to her mega-rich golfing boyfriend Rory McIlroy after fighting her way into the second round of the Australian Open on Tuesday.

Pitted against Wimbledon semi-finalist Sabine Lisicki, Wozniacki battled back from 3-0 down in the deciding set to come through the most testing of first-round draws with a 2-6 6-3 6-3 win at Hisense Arena.

Wozniacki's first success at a grand slam since last year's French Open came hours after reports that McIlroy had signed a multi-year deal with Nike believed to worth $250 million to the Northern Irishman.

"It wasn't really a big surprise to me. I kind of knew," Wozniacki said.

"So it was a long day for him yesterday, with a lot of media and a lot of things going on.

"But I think it's great. I'm so happy for him and I don't think it could have happened to a nicer person."

Wozniacki, the 10th seed this year after arriving in Australia last summer as the world No.1, apologised to McIlroy for upsetting his sleeping patterns before he starts his own season on Thursday in Abu Dhabi.

"He went to bed at midnight their time and woke up at three their time, then watched me and back to sleep for another couple of hours," the Dane said.

"I think I've messed up with his sleep a little bit. That's a true fan.

"It's great to have that support. I know that he's there watching on TV or on the computer always.

"He has a big tournament coming up as well, his first tournament of the year and hopefully he can get a good start to his year as well."

Lisicki, rightly described by Samantha Stosur's coach David Taylor as a high-risk player, clubbed 45 winners to Wozniacki's 12, but also committed a whopping 57 unforced errors to the Dane's eight.

"It's a tough first-round opponent," Wozniacki said.

"You never know what to expect ... so you just have to be on your toes all the time.

"I'm just happy to be through to the next round. Today I had to get my fighting spirit up."
