Radek Stepanek ensured the Czech Republic successfully defended their Davis Cup title as he claimed a straight-sets victory over Serbia's Dusan Lajovic to complete a 3-2 win in the final at Belgrade Arena.
The world number 44 became the first player to win consecutive fifth singles rubbers in the final after outclassing Lajovic, ranked down at 117 in the world, in what was undoubtedly the biggest match of his 23-year-old opponent's career.
Stepanek, who beat Nicolas Almagro in four sets in the fifth match of last year's final - in which Czech Republic defeated Spain 3-2 - comfortably outplayed the young Serb to record a 6-3 6-1 6-1 triumph.
Earlier on Sunday, Novak Djokovic made sure the final went to a fifth rubber against the defending champions as he saw off Tomas Berdych.
The world number two claimed a 6-4 7-6 (7-5) 6-2 victory over the 28-year-old in two hours and 42 minutes to level the contest at 2-2.
The Czech Republic took a 2-1 lead on Saturday when Stepanek and Berdych needed only three sets to beat Iliya Bozoljac and Nenad Zimonjic 6-2 6-4 7-6 (7/4).
But on Sunday and in front of his home crowd, the 2013 Australian Open winner ensured the match would go to a final rubber as Serbia attempt to wrestle back the title they won in 2010.
Lajovic, winner of the 2012 Samarkand Challenger, was a late replacement for the hosts after Janko Tipsarevic was ruled out due to injury on Thursday night.
Tipsarevic was forced to admit defeat in his battle to recover from a heel injury sustained in Valencia in October, denting Serbian hopes of winning a second title after their 2010 final triumph over France.
Stepanek took a 4-1 lead in the first set before the young Serb pulled it back to 4-2 and then 5-3, but the 34-year-old went on to claim a 6-3 win and leave Czech Republic two sets away from retaining the title.
Lajovic looked like he was struggling to read what Stepanek was going to do and fell 4-0 behind in the second set, working hard to return as his opponent had him running all over the court.
The Serbian won the following game but his errors were pilling up and it was going to require a mammoth effort to come back after the Czech took the next two games to put the visitors two sets up.
The 34-year-old Stepanek, who also broke his own record as the oldest player to win a live fifth rubber in Davis Cup history, took the first game before Lajovic held his serve to make it 1-1.
Djokovic and the Serbia team were willing their man on from the sidelines but with telling experience over his young opponent, Stepanek made it look almost easy as he won the next four games.
The crowd were still getting behind Lajovic as the match was drawing to a conclusion but his defensive lob went long.
Stepanek then put away a forehand and a big serve out wide before a clinical smash made it 6-1 and handed the Czechs their second consecutive title.
