Australian tennis great Sam Stosur has lavished praise on boom teenager Emerson Jones ahead of her grand slam debut.

Jones, 16, is the world’s No.1 junior girls player and lived up to that billing with a stunning demolition of Wang Xin at the Adelaide International on Monday.

The Queensland prodigy is the daughter of Olympic triathlon silver medallist Loretta Harrop and handed world No.37 Wang a 6-4, 6-0 defeat in Adelaide.

Jones will now play world No.9 Daria Kasatkina in the round of 16 on Wednesday night.

Stosur, the 2011 US Open champion, hit with Jones two years ago and the talent was obvious.

“I was really surprised how well and how hard she hit it, at that stage only 14 years old,” Stosur told ABC Sport.

“She just competes and goes for it. And hit some great shots on the move and try and dictate play.”

Jones has been granted a wildcard for the Australian Open.

She is the first Australian to rise to No.1 in the junior girls rankings since Jelena Dokic in 1998.

Jones is coached by Stosur’s former mentor Dave Taylor.

The now retired Stosur urged Jones to “play with no fear and enjoy the moment” of her first senior grand slam.

“She’s a really good competitor. She moves really well, she’s not afraid to go for it and play aggressive,” she said.

“She’s had experiences on the big courts, on these grounds, and playing at home, but obviously playing your first grand slam is a very different prospect.

“And obviously, depending on what the draw looks like and everything else… but I’m really excited to watch her play and I know she’s going to give it everything she’s got. She’s really excited for the opportunity and what a chance to be able to do it at 16.”

Jones has also shown a level head when asked about comparisons between her and former world No.1 Ash Barty.

“I find it really exciting that people say ‘she did this and that’ and I am following in her footsteps,” Jones said.

“But I just think we’re all on our different journeys and I just want to see how I go.

“Obviously, Ash Barty was amazing, so it would be very hard to keep up with that.”
