American 17-year-old Amanda Anisimova has notched one of the biggest wins of her burgeoning career, stunning 11th seed Aryna Sabalenka in straight sets to move into the Australian Open fourth round.

The youngest player remaining in the women’s draw blew the highly rated Belarusian off the court 6-3 6-2 in a little over an hour on Friday.

Sabalenka is the second seeded scalp in two matches for the 87th-ranked Anisimova, who swatted aside 24th seed Lesia Tsurenko in the second round.

Scrambling from side to side on the baseline, Anisimova produced one of the shots of the first week, with a loopy slice forehand at full stretch getting past Sabalenka and landing in the corner.

“This is an unreal feeling. I’m really feeling good out here. I’m playing some good tennis,” the teenager said.

Anisimova will meet either No.8 seed Petra Kvitova, who she beat at Indian Wells last year, or Switzerland’s Belinda Bencic on Sunday for a place in the quarter-finals.

The youngster idolises 2008 Australian Open winner Maria Sharapova, who she could meet in the final eight if results go their way.

“Definitely Maria is someone I look up to so much. She’s an amazing athlete,” Anisimova said.

Sabalenka was the second Belarusian to take a third-round tumble on Friday, with Aliaksandra Sasnovich losing 6-0 6-3 to Russian Anastasia Pavlyuchenkova in exactly an hour.
