Joint is jumping as Aussie tennis teen wins first title

A rip-roaring display from the US-born daughter of a Sydney dad who has rocketed through the rankings in just 18 months since basing herself in Queensland left her emotional before she jets off to Paris for her Roland Garros debut.

Confirming herself as one of the sport's finest young talents, Joint added the singles crown to a maiden doubles victory she had annexed the day before.

"Must be something about Morocco," she beamed afterwards on court. "It's been a an amazing week. The conditions really tested both of us - this crowd was unbelievable."

In Paris, Joint will face a first-round encounter against Australian luminary Ajla Tomljanovic, who retired with illness after losing the first set of their semi-final on Friday.
