WATCH: Wozniacki plays "2 Truths and a Lie"

Caroline Wozniacki has a pretty impressive pokerface. The world No. 2 played a game of "2 Truths and a Lie" with the WTA, and maintained a cool expression throughout all three statements.

The three were 1) she was born in 1990, 2) she turned pro in 2005 and 3) she's a certified scuba diver. The most obvious one in this case, scuba diving, was the lie.

"I kind of get claustrophobic if I go too deep in the water," Woznaicki said. "So that wouldn't be for me."

After an early loss in Miami, the Australian Open champion is turning her sights on clay. To get ready, she's hard at work on an even softer surface—sand.
