BELGRADE, Serbia -- With the Davis Cup on the line, Radek Stepanek delivered again.
Stepanek gave the Czech Republic its second straight Davis Cup title Sunday, sweeping past Dusan Lajovic in straight sets in the fifth and decisive match to secure a 3-2 win over Serbia in the final.
The 6-3, 6-1, 6-1 win over 117th-ranked Lajovic made Stepanek the first player in the history of the tournament to decide consecutive finals in the fifth match. He defeated Spain's Nicolas Almagro last year.
"This is an amazing moment," Stepanek said.
"We both entered this match with a lot of tension," Djokovic said. "I managed to break his resistance in the second set."
However, Stepanek converted his first match point with a smash to send about a thousand visiting Czech fans at Belgrade Arena into wild celebrations, blowing trumpets and beating their drums.
Stepanek spread his hands on the court as Berdych and other Czech teammates mobbed him.
"It's difficult to find right words for emotions I am going through now," Stepanek said. "It was a completely different experience than last year. I was very focused, concentrated, I knew what to do on court. We made history for our country today."
Last year's victory for the first for the Czechs as an independent nation. Serbia won its only crown in 2010, beating France in Belgrade.
The 23-year-old Lajovic, who has a 5-12 record on the ATP tour and had never played in the Davis Cup before this weekend, replaced Janko Tipsarevic, who missed the final with a heel injury.
He also lost his first singles against Berdych on Friday -- his first career best-of-five-sets match -- and was thrust into by far the biggest match of his life against Stepanek. The Serb started well, breaking Stepanek in the opening game, but the 34-year-old Czech responded swiftly with two consecutive breaks to take a 5-2 lead.
Stepanek controlled the match, breaking Lajovic for 3-1 in the final set and added another before serving out the match.
"I was fighting to my last breath, but obviously this wasn't enough," Lajovic said. "Of course, I am very disappointed. Right now I need to cool off my head and think what to do next."
Serbia captain Bogdan Obradovic said his team's chances of winning the title were hurt by Tipsarevic's injury and a 12-month doping ban against Viktor Troicki, who helped Serbia win its only title.
"We couldn't find the real replacement for the two," Bogdanovic said. "Dusan is the young gun in our team. Hopefully, he is going to use the energy from the team and some experiences from those two matches for his career, even if it wasn't a success."
The Czechs got the crucial point in Saturday's doubles to go up 2-1. Then second-ranked Djokovic then kept alive Serbia's hopes by beating Berdych on Sunday.
Berdych was leading 5-4 in the second-set tiebreaker when he sent wide an easy backhand volley at the net. Then he lost a point on his serve, and Djokovic took his first chance to serve out the set.
Djokovic, who improved his winning streak to 24 matches since losing the US Open final against Rafael Nadal in September, converted his first match point with an ace, bringing cheers from the 17,000-strong boisterous Serbian crowd at the arena.
"It's really hard to find right and correct words to explain at what level he's playing and how strong Novak is," Berdych said. "He is now the best player when he's playing indoors."
