The pairing were only the fourth ranged German team in the rankings, and with only the top two securing an Olympic berth, missed out in favour of Laura Ludwig and Kira Walkenhorst, and Karla Borger and Britta Buthe.

But they enjoyed far better fortunes today, requiring just 33 minutes to beat top-seeded opponents Monika Brzostek and Kinga Kolosinska of Poland.

“We still are playing to win,” said the 26-year old Laboureur.

“It is our job.

"Defeating the Polish girls was satisfying, especially with their qualification for the Olympics and beating them before their home crowd.

"Winning matches will help relieve some of the disappointment, but it is still frustrating to know that we were so close.”

Laboureur and Sude were among eight pool winners today.

Others to enjoy success included United States' Lauren Fendrick and Brooke Sweat, who followed a 21-17, 21-17 win over 24th-seeded Rimke Braakman and Jolien Sinnema with a 20-22, 21-18, 15-13 victory in 45 minutes over ninth-seeded qualifiers Eduarda Lisboa and Elize Maia of Brazil.

Second-seeded Talita Antunes and Larissa Franca and fifth-seeded Agatha Bednarczuk and Barbara Seixas, both of Brazil, were among other pool winners.

Ludwig and Walkenhorst also progressed, along with fourth-seeded Heather Bansley and Sarah Pavan of Canada, sixth-seeded Madelein Meppelink and Marleen Van Iersel of The Netherlands, and 10th-seeded Elsa Baquerizo and Liliana Fernandez of Spain.

Action in both the men's and women's competition is set to continue tomorrow.
