Switzerland has qualified for the next round of the Davis Cup in the Europe/Africa I zone competition as it bids to return to the World group next year.
Playing without world number one Roger Federer, the Swiss were able to defeat Poland in two days in Kreuzlingen, canton Thurgau.
On Saturday, the doubles team of Yves Allegro and Michael Lammer overcame Mariuz Fysternberg and Marcin Matowski in four sets, 6-4, 6-3, 2-6, 6-3.
Lammer replaced Swiss number two Stanislas Wawrinka, who was returning from injury. Wawrinkra won his singles match on Friday, as did Stéphane Bohli.
The Poles were the favourites after participating in the end-of-year Masters tournament in Shanghai, which brings together the best eight doubles teams of the year.
Switzerland will travel in April to Minsk to face Belarus and its aging stars May Mirnyi and Vladmir Voltchkov in the next round.
