The Par 3 Contest is one of the Masters' many storied traditions. Former champions like Jack Nicklaus and Arnold Palmer as well as current players compete in the nine-hole event played at the club's par-3 course, and players often have their wives, children, friends or parents caddie for them.
Wozniacki revealed on Twitter that she'd be on McIlroy's bag in response to a question from European Tour player Thorbjørn Olesen, who is playing the Masters this week.
@thorbjornolesen yeah I am! Gonna be fun! Are you playing the par 3?

Wozniacki won't be the first women's professional tennis star to caddie in the Par 3 Contest; Chris Evert was on then-husband Greg Norman's bag on 2009.
And, sorry US Magazine, we're not likely to see Lindsey Vonn caddie for Tiger Woods in the Par 3 Contest. Vonn is recovering from knee surgery following a frightening skiing crash in February. Woods hasn't played the Par 3 since 2003. He has said he will play when his children are old enough to caddie for him. His daughter Sam is now 5 years old. Photo: Getty Images
