McIlroy says arm OK, girlfriend Wozniacki even better

US Open golf champion Rory McIlroy confirmed Thursday that he and top-ranked tennis player Caroline Wozniacki of Denmark are an item.

McIlroy, who attended Wozniacki's second-round match at the WTA's US Open tune-up at New Haven on Tuesday, has been linked to Wozniacki for weeks, the two giving their Twitter followers plenty of information on their budding relationship.

"Why it's going so well is that we have so much in common," said Northern Ireland's McIlroy, who said it would be fine to call Wozniacki his girlfriend.

"Obviously, different sports, but we're pretty much in the same position at a young age and we can talk about things that probably a lot of 21-, 22-year-olds can't talk about.

"It's nice to have someone that sort of understands what you're going through."

McIlroy had treatment on his injured right forearm at the Connecticut Tennis Center on Thursday, a day after hitting golf balls at the nearby TPC River Highlands course.

McIlroy strained a wrist tendon in the first round of the PGA Championship earlier this month.

"It's OK," he said. "It's not 100 percent."

McIlroy also confirmed he plans to play "maybe 17, 18 events" on the US PGA Tour next year.

"For me, I play my best golf over here and I just want to spend a bit more time over here," he said.

As for Wozniacki's sporting pursuits, he said he would be delighted if she could claim her first Grand Slam title at the US Open, which starts on Monday in New York.

McIlroy said the prospect of them both owning a US Open title was "pretty cool".
