NIS, Serbia (AP) -- Janko Tipsarevic beat Michael Ryderstedt of Sweden in straight sets Sunday to send Serbia to the Davis Cup quarterfinals against the Czech Republic.
Tipsarevic won 6-2, 7-6 (5), 7-5 to give Serbia an unassailable 3-1 lead in the best-of-five series on an indoor hard court in the central Serbian town of Nis. In the last match, Serbia's Dusan Lajovic beat Filip Prpic 6-4, 6-4 for the final 4-1 score.
The Serbians won the two opening singles matches, but Swedes Johan Brunstrom and Robert Lindstedt beat Tipsarevic and Nenad Zimonjic in Saturday's doubles.
Serbia played without top-ranked Novak Djokovic, who is resting after winning the Australian Open.
