Intro:

Stanislas Wawrinka and Roger Federer watch on as doubles pair seal victory for Swiss

Script:

After Roger Federer and Australian Open winner Stanislas Wawrinka gave Switzerland the lead against Serbia in the Davis Cup on Friday, it was up to Marco Chiudinelli and Michael Lammer to seal victory in the doubles on day two in Novi Sad.

The Swiss pair won the opening set seven points to three on a tie-break against Filip Krajinovic and Nenad Zimonjic.

But the home side hit back by winning the second set 6-3.

It was the Swiss pairing digging deep at vital moments though, they won the third set with another tie-break.

That appeared to break the spirits of the Serbia pair and Switzerland went 4-1 up in what would become the final set.

They took it 6-2 and now face either Belgium of Kazakhstan for a place in the semi-finals.
