Switzerland's Laciga brothers have won through to the semi-finals of the Berlin Beach Volleyball Open, where they will meet their compatriots, Swiss duo Stefan Kobel and Patrick Heuscher.

Paul and Martin Laciga sailed through the first four rounds of the latest leg on the beach volleyball world tour, when they claimed a decisive victory after every match.

Kobel and Heuscher had to work a little harder to make it through to the last four of the Berlin tournament. The pair suffered an early setback when they went down to the Brazilian partnership Emanuel/Tande in the second round, losing 19-21, 18-21.

But a strong recovery in the third and fourth rounds guaranteed the Swiss pair a place in the semi-finals, the furthest they have ever reached in the annual tournament.

Whichever Swiss pair emerges victorious from the semi-final tie will go on to play the winner of Sunday's other semi-final match, between Emanuel/Tande and the Australian duo, Zahner/Prosser.

The Laciga brothers, who hail from Fribourg, already hold the 1998 and 2000 world titles and came fifth in the 2000 Sydney Olympics.
