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

In a mouth-watering Roland Garros appetiser, Gavrilova is gunning to end Stosur’s remarkable 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.

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.

Win or lose on Saturday night, both stars will head to Roland Garros for the season’s second grand slam event brimming with belief after storming into their first finals of the year.

But the opportunity to land her maiden career title and knock Stosur off her perch to further underline her credentials as a genuine Open contender is Gavrilova’s big motivator.

“I’m ready. I’m really hungry to win a tournament,” the 23-year-old said after dispatching Garcia in 76 minutes for her seventh win in eight matches on European clay.

“It’s actually a big one because whoever wins this tournament is going to be the No.1 in Australia.”

Backing up her giant-killing run to the quarter-finals last week in Rome, Gavrilova went nine service games unbroken to march into her second final, having lost to Svetlana Kuznetsova in her native Russia last October.

Stosur ‘ready’ for Dasha

Stosur, though, has her own intentions, and the world No.24 and former US Open champion is also acutely aware of what’s on the line.

“It’s obviously a unique situation. Even playing Australians, it doesn’t happen very often,” said Stosur, chasing a ninth career trophy in her 24th final.

“But we know each other very well. We’ve practised a lot together at home and it’s going to be a tough one.

“She’s playing very well and I’m going to have to be right at the top of my game to win.

“I’m certainly ready for Dasha to come out and fight and do whatever she can to try and play very well and play a good match, as will I.

“I know there’s things riding on the match for her, as there is for me.

“So we’re going to compete hard but, at the end, shake hands and we’ll be fine after the match no matter who wins.”

While presently separated by just one spot in the world rankings, Stosur is 10 years Gavrilova’s senior and hopes the gulf in experience will help.

“It’s a big thing to try to win your first final. I was in eight finals before I won one,” said the one-time world No.4.
