The Brazilians are in form as they are fresh from consecutive gold medal matches in World Tour events having claimed victory in the three-star Qinzhou Open and second at the four-star tournament in Yangzhou.

"We arrived from China on Monday and we are still dealing with the time-difference and the sand, which is a little bit different than the one we played at in China," Cavalcanti said.

"It wasn’t our best game but we were very focused and aware that we are still adapting to the tournament, so it was a good start."

Two other Brazilian teams will be joining Cavalcanti and Silva in the women’s main draw.
