Wozniacki plays caddy to boyfriend McIlroy at Augusta!

She may be the girlfriend of a two-time Major-winning golfer, but Caroline Wozniacki needs to hone her skills for the sport.

The tennis star was caddying for her World No.2 other-half Rory McIroy at the lighthearted Masters Par Three competition at Augusta on Wednesday when he let her take one of his tee shots.

But despite hand-eye coordination that has seen her top the rankings in her day job, the Danish racket-weilder plopped her effort straight into the lake, the Sun reported.

Boyfriend McIlroy saw the funny side and planted a smacker on her lips when they got to the green -- a fairway to make up for it.
