Caroline Wozniacki has been receiving some tips on how to play golf, but not from her boyfriend, world No. 1 golfer Rory McIlroy, the tennis star said Monday.

Instead, Wozniacki has received advice from former tennis No. 1 Yevgeny Kafelnikov, now the Russian national golf champion.

"I actually really enjoy golf. I think it's a fun sport to play and I think I've got hooked on it a little bit but not as much as much as Yevgeny," she said.

"He actually gave me a few hints on the tennis court how to play golf when we were in Australia this year."

Despite Kafelnikov's input, the Dane will remain strictly a recreational golfer, as well as supporting McIlroy at tournaments, she said.

"I think I'll stay playing occasionally and going out to watch."

Wozniacki, ranked world No. 11 after an underwhelming year, is to face either former French Open champion Francesca Schiavone or Poland's Urszula Radwanska in the second round of the Kremlin Cup in Moscow this week after getting a bye in the first round.
