Caroline Wozniacki thinks her recent slump and slide in the rankings has more to do with bad luck than bad tennis – and that it certainly isn’t related to her relationship with golfer Rory McIlroy.

The former top-ranked Dane wasted two match points in the second set before losing 5-7 7-6 (7/4) 6-4 to Tamira Paszek of Austria in the first round of Wimbledon on Wednesday.

Wozniacki has yet to win a title this year, was eliminated in the third round of the French Open and lost her first match at the grass-court warmup tournament at Eastbourne this month.

Having ended both 2010 and 2011 as the world’s top-ranked woman – albeit without ever winning a major – she has fallen to No.7.

So could it be that her highly publicised relationship with McIlroy – which began a year ago – could be affecting her tennis?

“No,” was the short and terse answer from Wozniacki when asked.

Instead, she pointed to factors like luck and the fact that Paszek hit two balls on the line when saving one of her match points.

“It was a good match, good tennis, but that doesn’t really help me. I lost in the first round,” Wozniacki said.

“Tomorrow no one will remember how great a match it was, they’ll just remember who won. It’s not a nice feeling.

“Those are some of the matches that it’s really great when you win them, but also really sucks when you lose. Especially after having two match points and not taking them.”

McIlroy, meanwhile, will be playing in the Irish Open on Thursday, trying to break out of his own recent dip in form that has seen him miss the cut in four of his past five tournaments and lose his No.1 ranking to Luke Donald.

Wozniacki said she has yet to decide whether to fly to Northern Ireland to support him, having travelled to several of his tournaments previously over the past year.

“To be honest, right now I don’t know what I’m going to do,” she said. “I don’t know what my plans are at the moment.”
