Miami, FL, USA, 29 March 2015 | tennis.com.au

Daria Gavrilova has continued her fantastic run at the Miami Open, advancing to the last 16 with a straight-sets victory over Japan’s Kurumi Nara.

Following on from her stunning upset of No.2 seed Maria Sharapova in her previous match, Gavrilova picked up right where she left off, beating Nara 6-0 7-5(5).

Next up for the Russian-born Aussie is the winner of the match between 14th seed Karolina Pliskova and Spanish wildcard Paula Badosa Gibert.

Earlier on Saturday in Miami, Australian qualifier James Duckworth fell to 29th seed Fernando Verdasco.

Duckworth, who went down in straight sets to the Spaniard a fortnight ago at Indian Wells, pushed Verdasco harder this time, taking the first set before losing 4-6 6-2 6-1.

Another Aussie, Sam Stosur, staged a magnificent comeback before falling to Venus Williams in the third round.

Williams won 6-4 7-6(3) to advance to the fourth round, where she will take on Caroline Wozniacki.

Having dropped the first set, Stosur slumped to a 5-1 deficit in the second set before mounting an exciting turnaround.

Three times Williams served for the match, only to be broken on each occasion.

The third of those sent the set to a tiebreak, which Stosur began in style with a crisp backhand winner down the line.

Yet errors – she finished the match with 34, to just 14 winners – began to creep back into her game.

Williams forged ahead 6-2 to gain her first match point opportunities of the contest, and although Stosur saved one, Williams was able to seal victory in one hour and 40 minutes.
