Barty 1-0 Kenin*
Barty reacts well to a short ball and slices it on the volley. Kenin overcooks a forehand to bring up 40-15 but Barty then drags one of her own wide.
The Aussie recovers well to get her first serve in and holds comfortably.

BBC Sport at Melbourne ParkAshleigh Barty has been keen to play down the hype. That in itself is quite a skill when your face and name is plastered all over Melbourne.
In the Channel 9 television coverage of the semi-final, she appeared in three commercials during one ad break.
Unsurprisingly she is also on the front page of the Herald Sun, who go with a Happy Monday-style (but probably not inspired) pun in their headline.

And these posters adorn the billboards on the walk up to Melbourne Park.

*Barty 0-0 Kenin
Right, here we go. Both players are wearing the exact same outfit but Barty has gone a bit rogue with a white cap rather than green.

Barty v Kenin
American Sofia Kenin is playing in her first Grand Slam semi-final but knows how to deal with big-name opponents having knocked 23-time major champion Serena Williams out of the French Open last year.
"I feel like that match really changed things," said Kenin. "Obviously saw that I can play on this level, I could play with the best. Of course, it just happens to be Serena, my idol.
"I feel like after that, things took off."

Barty v Kenin
World number one Ashleigh Barty is not being swept away with growing public excitement as she bids to become the first Australian woman to reach the final of the home tournament in 40 years.
"Obviously it's exciting. But I don't pay attention to it, honestly," French Open champion Barty said.
"I'm here to try and do the best that I can. Hopefully I can bring a smile to a few faces around our country and around the world."
She is aiming to emulate Chris O'Neil - the last Australian to win a singles title in 1978.
"This is a new experience for me," Barty said. "I'm just going to try and take it in my stride, learn as much as I can and go from there."
