Barty through to semi final

Ash Barty is one win away from becoming the first Australian woman since Wendy Turnbull in 1980 to qualify for an Australian Open final, having defeated number seven seed Petra Kvitová in straight sets at Rod Laver Arena on Tuesday afternoon.

The first set lasted 70 minutes before Barty claimed it in a tie break, having earlier avoided a set point. She went on to win the second set more comfortably after an early double break of serve, winning 7-6 (8-6) 6-2.

Both players broke each other's serve early on the first set in a match up between two top ten seeded players in the tournament, both playing the majority of points from behind the baseline in a power battle between the two.

Barty held on in a tense tie break to claim it eight points to six, before immediately opening the match up in the second set with a double break, consolidating to claim a spot in the final four.

Barty will play American Sofia Kenin for a spot in the final, after the 14th seed defeated Tunisian Ons Jabeur in her quarter final match up 6-4, 6-4.

Roger Federer is facing American Tenys Sandgren in his quarter final, while Novak Djokovic plays Canadian Milos Raonic tonight.
