The Czech Republic got within a point of defending the Davis Cup title as Tomas Berdych and Radek Stepanek beat Serbia's Ilija Bozoljac and Nenad Zimonjic in Saturday's doubles in Belgrade.
Berdych and Stepanek won the fourteenth of their 15 Davis Cup doubles rubbers together as they swept the hosts 6-2, 6-4, 7-6 (7/4) in two hours and 12 minutes to give the Czechs a 2-1 lead over 2010 champions Serbia.
In Sunday's reverse singles, world number two Novak Djokovic will first take on Berdych and Stepanek will then face Dusan Lajovic, world number 117 who has replaced the injured 36th-ranked Janko Tipsarevic.
On Friday, Djokovic, the recently-crowned ATP World Tour Finals champion, beat Stepanek, world number 44 in the opening singles, 7-5, 6-1, 6-4.
Seventh-ranked Berdych then put the Czechs level, sweeping Lajovic 6-3, 6-4, 6-3 on the hardcourt of the sold-out Belgrade Arena sitting more than 15,000 people.
