Ash Barty has matched her career-best result at the Italian Open by advancing to the third round.
The world No.1 scored a straight-sets win against Kazahkstan's Yaroslava Shvedova, recovering from a slow start to record victory in 78 minutes.
"Room to improve without a doubt, but overall I'm happy to get through and get another opportunity tomorrow to work on a few things," Barty said after posting a 6-4 6-1 win.
"I feel like I'm really getting myself into the tournament here in Rome. I think it's such a beautiful, iconic event and I'm really excited now that I get another opportunity tomorrow."
In-form Russian Veronika Kudermetova is Barty's next opponent. The 24-year-old has been quickly climbing the rankings this season, rising to a career-high No.28 this week. This will be their first career meeting.
Former Roland Garros champion Jelena Ostapenko proved too strong for Australia's Ajla Tomljanovic, scoring a 6-2 7-6(3) victory in their second-round encounter.
John Millman's tournament is also over, beaten by world No.9 and local hope Matteo Berrettini in straight sets.
It was a tough day too for Aussies in doubles action. Ellen Perez and Chinese partner Zheng Saisai were beaten in the second round, while Alex de Minaur and German Jan-Lennard Struff lost to the reigning Australian Open champions.
Aussie combination Max Purcell and Luke Saville couldn't capitalise on a 6-3 match tiebreak lead, losing the final seven points of the match in their showdown with Brits Andy Murray and Liam Broady.
