Head to head
They haven't met each other since they turned pro, but have met each other 3 times as juniors, all of them on hardcourt and Wozniacki won all 3 times handing out two bagels and only losing 9 games in 6 sets total: http://www.itftennis.com/juniors/pla...nent=100041250
But it's many years ago when both were very young. At their first match in October 2003 Wozniacki was only 13 years old and 15 years old at the Orange Bowl 2005 girls 18s championship.
