Tennis news - Women's round-up: Ashleigh Barty and Anastasia Pavlyuchenkova secure dominant wins
Home favourite Ashleigh Barty is through to the fourth round of the Australian Open after beating Maria Sakkari in straight sets 7-5 6-1 at the Rod Laver Arena.
The 15th seed is yet to drop a set this week, but required medical attention at the end of the opener after complaining of a stomach problem,. She managed to shake off the issue to progress in straight sets.
Barty had to save two break points in her opening service game, but she managed to get out of a tight spot and it was Sakkari who blinked first with an unforced error.

The Greek benefited from a mis-hit from the Australian to break back immediately, but a succession of aggressive double faults allowed Barty to gain the upper hand and put one foot in the fourth round with the first set.
Barty, with the home crowd spurring her on, fed off Sakkari's inconsistency to clinch the crucial first break of the second set as more intelligent play saw her race clear and finish the job in style.
The 22-year-old will face either Maria Sharapova or for a place in the quarter-finals.
