Pera, ranked 85th in the world, proved too strong in a 6-2 6-4 victory to set up a quarter-final meeting against Xinyun Han.

The left-hander won the last five games of the first set and never looked back and said afterwards her second serve was key.

"You can say I'm satisfied. I played well," Pera said.

"She's a tough opponent and I'm thrilled to be in the next round. I think she was struggling a lot with my second serve.

"I was able to break her a couple of times and that's what made the difference."
