Ashleigh Barty has progressed to the fourth of the Miami Open after winning her all-Australian showdown against Samantha Stosur in straight sets.
In the second career match between the two players, it was the nation’s top-ranked player who came out on top against former US Open champion Stosur.
Barty earned a comprehensive 6-0 6-3 win in 58 minutes and the scoreline could have been even more definitive.

The young star held match points for what would have been a 6-0 6-1 victory in just 48 minutes before being broken by Stosur.
It was their first meeting since Stosur won 6-4 6-4 in Miami two years ago.
Barty, who will face seventh seed Kiki Bertens or the 20-year-old Viktoria Kuzmova in the fourth round, could enter the world’s top 10 rankings with a deep run.
Elsewhere, world No.2 Petra Kvitova was extended to three sets before the Czech overcame Croatia’s Donna Vekic in the third round.
Two-time Wimbledon champion Kvitova finally prevailed 6-4 3-6 6-4 in the clash between two heavy hitters, requiring more than two-and-a-half hours. Kvitova, the third seed, will next meet France’s Caroline Garcia.
Garcia had earlier knocked out 15th seed Julia Goerges, of Germany, 6-0 7-5.
Serena Williams, meanwhile, has withdrawn from the Miami event with a left knee injury, tournament officials said on Saturday.
It is the second consecutive WTA event in which the American has been unable to continue, after her retirement from last week’s Indian Wells event with illness.
“I hope to be back next year to play at this one-of-a-kind tournament in front of the incredible fans here,” Williams said.
Former world No.1 Williams showed no signs of injury while winning her opening match against Swede Rebecca Peterson 6-3 1-6 6-1.
