Barty, Gavrilova eye watershed wins

Ashleigh Barty and Daria Gavrilova won't be shackled by the occasion as they chase watershed Wimbledon wins on Saturday.

Australia's best and last two women's singles hopes are both eyeing fourth-round berths for the first time at The All England Club.

While Gavrilova has twice reached the last 16 of her home grand slam in Melbourne, Barty has never ventured so far at a major anywhere.

But the 22-year-old former Wimbledon junior champion is vowing not to hold back against 14th seed Daria Kasatkina.

"I've learned much better the past 18 months to play with more freedom in every match regardless of if it's a first-round match or a final, and just try to play the way that I want to play," Barty said.

"I know if I do that and play to my ability that there are a lot of girls out there that I can beat.

Seeded 17th and boasting a tour-best 22 wins on grass in 2018, Barty has never been tested by her Russian opponent.

"I don't even actually know if we've practised together, so it's a bit of a different one for me," Barty said.

"I'll go out there, I'll back myself and try and get the job down."

If she does, Barty is guaranteed to play a lower-ranked rival - either 28th seed Anett Konaveit or world No.47 Alison Van Uytvanck - for a spot in the quarter-finals.

The singles is Barty's only focus after losing her first-round mixed doubles match on Thursday with Thanasi Kokkinakis, the wildcards going down 6-7 (10-12) 7-6 (7-2) 9-5 to Fabrice Martin and Raluca Olaru in a three-hour, 11-minute cliffhanger.

The first-round elimination of pre-tournament title favourite and two-time champion Petra Kvitova has also presented Gavrilova with a huge opportunity.

Gavrilova, the 26th seed, takes on Kvitova's conqueror, Aliaksandra Sasnovich and beat the Serb in their only previous encounter.

But she's not underestimating the world No.50.

"She's had a great year. She's been on a roll and she's actually been really tricky on the grass and she hits the ball super low over the net," Gavrilova said.

"She doesn't hit it flat. It's just a different ball and I think she has a pretty good effective serve on the grass.

"It's going to be tricky."

Either Latvian 12th seed Jelena Ostapenko or Russian qualifier Vitalia Diatchenko will be awaiting the winner in the last 16.
