The no. 1 seed got some revenge on Osaka, who beat her in the third round of the Australian Open this year.

Barty led 3-0 in the first set but Osaka fought her way back into the match but Barty did what she did best winning 80 percent of the points played when she served.

She broke third-seeded Osaka three times and didn’t face a break point on her own serve.

Barty dropped just nine points on serve overall in the entire match and made it four straight set wins.

“I think it’s been a very clean week for me. I’ve served well and gotten myself into return games very well,” Barty told tennis.com.au.

“I think when I first got on the grass, I instantly felt comfortable.

“I’m obviously feeling very good this week and I hope to go one more tomorrow.

"Being in a final again is always a positive no matter where you are,” she said.

Barty will face Johanna Konta early tomorrow morning (12am AEST) as she beat defending champion Donna Vekic 6-2 6-3.

The two have met in the quarterfinals of the tournament in 2017 where Konta came away the winner from the match.

Konta is aiming to become the first Brit to win a WTA singles grass title at home since former Wimbledon champion Virginia Wade in Eastbourne in 1975.

Barty is into her second final of the year after losing in January to former world No.1 Angelique Kerber at the Sydney International.
