TOKYO, Japan – Japan is a special place for longtime friends and rivals Caroline Wozniacki and Dominika Cibulkova. The two played their first junior match against one another in this very country all the way back in 2004.

Both have become mega-stars on the WTA tour since, but both have found time to give back on days like Monday, when the pair participated in a kid’s clinic at the Toray Pan Pacific Open.

Cibulkova is the No.6 seed in Tokyo and plays her first match against Lucie Safarova; former No.1 Wozniacki opens against 2015 Tokyo finalist Belinda Bencic. Both play on Center Court on Tuesday.
