Blossoming Australian tennis star Lizette Cabrera already has a mental edge over her round-two opponent at the Hobart International.

On Tuesday the 19-year-old Queenslander will take on Croatian qualifier Jana Fett after both women had surprise victories on debut in a WTA main draw.

The problem for Fett, 20, is that if she beats her friend Cabrera she progresses to Hobart’s quarter-final, due to be played on the same day she has to be at Melbourne Park to start qualify for the Australian Open.

“It’s either this or that,” Fett said of the clash in scheduling.

“I’ll play for sure and then we’ll see how it goes.”

Cabrera doesn’t have the same headache, having already been handed a wildcard entry for the Open on the back of strong recent form.

The world No.208 toppled Misaki Doi in her first-round match on Sunday in a surprise upset over the 40th-ranked player from Japan.

“I want to keep going and just ride the momentum,” Cabrera said after the victory.

Fett on Monday disposed of former French Open champion Francesca Schiavone in straight sets.

“This is a good start, I’ve been injured last year so I just started playing in October,” she said.

“I had wrist surgery – my ligament broke (and) I had nine months off but it’s all good now.

“It’s been sore for two years but I’ve been playing with it, taking painkillers and stuff. And then I had to have surgery.”

Prior to the evening clash between Cabrera and Fett, world No.40 Monica Niculescu meets 73rd-ranked Belgian Kirsten Flipkens on centre court.

On Monday Flipkens disposed of Aussie wildcard Jaimee Fourlis 7-6 (12-10) 6-4.

Overnight the tournament’s top-ranked player, world No.22 Kiki Bertens, overcame Germany’s Annika Beck 6-1 6-2.
