The second seeds were in confident form as they claimed a 21-19, 21-15 win over the German pair in Pool B of the men's competition at the Red Bull Beach Arena on Danube Island.

"The goal is to play each match like the last one, we are only focused on the next match," said Smedins.

"We are not looking at any other matches, we are just preparing for this one, that is all. 

"We played a little bit better with the service today, and they didn’t move their legs as good.

Jefferson Santos Pereira and Cherif Younousse of Qatar, the 23rd seeds, also secured their second success of the tournament in Pool B as they overcame Carlos Rangel and Jonathan Golindano of Venezuela.

It went to three sets but the Qataris triumphed 21-18, 22-24, 15-10.

In the women's tournament, Agatha Bednarczuk and Eduarda Lisboa of Brazil maintained their 100 per cent record in Pool C with a narrow win against Canada's Julie Gordon and Camille Saxton.

Reigning world champion Bednarczuk, who won the 2015 women's title in The Hague with Barbara Seixas, and Lisboa were made to work hard for their victory before prevailing 27-25, 15-21, 15-7.

Their Brazilian counterparts Talita Antunes and Larissa França, who lost in the bronze medal match at last year's Olympic Games in Rio de Janeiro, swept aside American pair Emily Day and Nicole Branagh 21-15, 21-9 in Pool A.

Summer Ross and Brooke Sweat of the US were another pairing to clinch a second consecutive win at the event in the Austrian capital as they were on the right side of a 21-15, 25-23 scoreline in their Pool E clash with Tatyana Mashkova and Bakhtygul Samalikova of Kazakhstan.

The tournament in Vienna continues tomorrow.
