Tennis aces Samantha Stosur and Daria Gavrilova will clash for the Australian No.1 ranking after setting up a high-stakes final in Strasbourg.

In a mouth-watering French Open appetiser, Gavrilova has the chance to end Stosur's record-long 450-week reign as Australia's queen of the court after continuing her hot claycourt run with a 6-4 6-2 semi-final dismissal of Caroline Garcia on Friday.

Under siege following a near-decade as national No.1, Stosur responded with an equally impressive 7-6 (7-0) 6-4 victory over Peng Shuai to lock in the first all-Australian WTA title decider in 12 years.
