Alex De Minaur forced out of Adelaide International

Kiki Bertens of the Netherlands hits a return shot to Ashleigh Barty of Australia during their WTA Finals Tennis Tournament in Shenzhen China’s Guangdong province Tuesday Oct. 29 2019

She blitzed Marketa Vondrousova in the final, 6-1 6-3, to capture her first grand slam, one of four tournament triumphs in a year propelling the Queenslander to world No.1.

"Roger's done a pretty good job of it over an extended period", she said.

"It's something I pride myself on is that no matter what the score is, I try and hang around for the whole match every time", Barty said after the match.

"It was just me finding the middle of the racquet, finding my groove. obviously it's natural to find your rhythm and find your groove the more matches you play".

"It's phenomenal to play at home again, it's my backyard where the Brisbane International is played, I train there day in, day out", she said.

"She probably doubted herself completely", Tyzzer told reporters ahead of Barty's first-round match on Tuesday at the Adelaide International.

On paper, Barty is the clear favourite to win this match, because of her higher world ranking, and superior head-to-head record.

"I felt like I was doing the right things".

The 20-year-old confirmed he had been desperate to play at the Adelaide International and said the city has a special place in his affections after he won his first Davis Cup match here against Bosnia and Herzegovina nearly 12 months ago.

But the 31st-ranked Russian, who now stands 3-3 in their head-to-head, lost her own serve on a forehand wide as Barty took a 6-5 lead and closed out the win a game later after two hours, 10 minutes. Barty broke Pavlyuchenkova in the 11th game that served for this match.

"I'm very proud of myself the way that 5-all game I was able to regather and then get that last bit of momentum that I needed".

Qualifying for the $2 million event began yesterday, while the tournament proper begins 5pm today (Sunday) and will be preceded by a Rally for Resilience, featuring Halep and former Australian Open victor Angelique Kerber, with proceeds to go towards supporting the bushfire relief appeal.

"I started to feel something from the second match of the ATP Cup, against (Denis) Shapovalov".

In the men's draw, Britain's Dan Evans reached the quarters with a 7-5, 6-2 defeat of Alexander Bublik.

Wimbledon champion Simona Halep marked her first singles match of the new season with a straight-sets win over Ajla Tomljanovic.

Sandgren, unseeded this year, beat doubles specialist and local hope Michael Venus 6-4, 6-3, serving up 15 aces along the way.
