Roger Federer will open Switzerland's Davis Cup first-round match against Serbia by playing Ilija Bozoljac on Friday, while Australian Open champion Stanislas Wawrinka faces Dusan Lajovic.
Switzerland is an overwhelming favorite against Serbia, last year's finalist and the 2010 Davis Cup champion, which will be without Novak Djokovic. The second-ranked Serb decided to rest after losing to Wawrinka in the Australian Open quarterfinals. Lajovic at No. 102 is Serbia's highest-ranked team member.
Federer was a surprising inclusion in the Swiss team, having played only one first-round match since 2004. He last represented Switzerland in September 2012, helping win a relegation playoff against the Netherlands.
The series opens Friday on indoor hard court. Doubles are Saturday and reverse singles Sunday.
The winner plays Belgium or Kazakhstan in the quarterfinals in April.
