Rio de Janeiro, State of Rio de Janeiro, Brazil, 8 August 2016 |

Sam Stosur has overcome the stiff challenge of Jelena Ostapenko to advance to the second round of the women’s singles in Rio.

Stosur beat the Latvian teen 1-6 6-3 6-2 on Tuesday.

The win sets up a second-round meeting with Japanese lefty Misaki Doi, who beat Wimbledon quarterfinalist Yaroslava Shvedova.

Stosur beat Doi just a few months ago in the opening round at Roland Garros and leads their head-to-head seriesĀ 3-0.

Fellow Aussie Daria Gavrilova was unable to join Stosur in round two, falling to the mighty world No.1 Serena Williams.

Gavrilova went down 6-4 6-2, but did come out on top of this spectacular rally on Centre Court at the Olympic tennis venue.

The other Aussie in action, Sam Groth, lost 6-4 6-2 to Belgian No.8 seed David Goffin.
