It's a credit to just how phenomenal Barty's rise has been that many pundits don't even know she's a Grand Slam doubles champion and still world number-six in the dual version of the spot.

It was her incredibly fruitful partnership with fellow Aussie favourite Casey Dellacqua that spawned her greatest success on the doubles court, but now Barty is teaming up with legendary Belarusian Victoria Azarenka for the Canadian Open.

The number six seeds have set up a (nearly) all Aussie encounter in Toronto, where they'll face Storm Sanders and Monique Adamczak.

While Sanders will be familiar to many tennis fans after numerous entrances to the Australian Open, the now doubles-focused left hander is partnering with the vastly experienced Adamczak, a combination that has garnered some success over the past two years.

The respective 24 and 36-year-olds will be notable underdogs for the encounter, but should provide stiff competition for Barty, who hasn't played a tournament since her Round of 16 Wimbledon exit to Allison Riske.

The four face each other 2am tomorrow, AEST.
