PRAGUE -- Six finals, six victories.
The Czech Republic kept its perfect record in the Fed Cup finals by capturing the trophy for the sixth time in eight years by defeating the defending champion United States.
Katerina Siniakova saved two match points before defeating Sofia Kenin 7-5, 5-7, 7-5 in the first reverse singles on Sunday to give the Czechs an insurmountable 3-0 lead over defending champion United States in the best-of-five final.
It was the first victory for the Czechs over the United States -- since the country was created after the split of Czechoslovakia in 1993 -- after four defeats in the Fed Cup.
The Czechoslovakia team that won five Fed Cup titles was 2-6 against the U.S.
"It was an unbelievable match for me," Siniakova said. "It was up and down, with nerves. I'm extremely happy that I won. I thank all who came for their support. It was felt."
U.S. captain Kathy Rinaldi said she was proud of her team despite the loss.
"We didn't get the result that we wanted but nobody can say we didn't give all out there," Rinaldi said after her first loss as the captain.
"That match today, both girls, both players were incredible," she said. "I'm so honored to have been part of that match, they really fought hard, the points were incredible, it's just something I never forget."
In a hard-fought match at the O2 Arena, the 22-year-old Czech saved two match points when Kenin was serving at 5-4, and went on to convert her second match point on the indoor hardcourt in front of 14,500 fans.
"It was a long match, a lot of points, a lot of effort, long points," Kenin said. "We fought hard till the end. It's disappointing for me `cause I had like two match points but couldn't turn things around. But I fought my hardest and I did everything I could."
Siniakova wasted a 3-0 lead in the final set and the 19-year-old Kenin, who was playing her second match in her debut Fed Cup tie, fought back.
Kenin, who wasted three break points at 5-5, hit 43 winners but also made 76 unforced errors. Siniakova hit 24 winners.
"It was horrible, the worst (moment)," Siniakova said about the match points she faced. "But it's not the end until the final match point is converted."
At 3-0 down in the third set, Kenin needed treatment for what seemed to be a thigh muscle problem. The treatment was then repeated several times.
"It was obviously painful for me and I felt like it was just hard for me to move," Kenin said.
Trailing 3-1, the American wasted five break points in a game that took 19 minutes.
The U.S. is the most successful country in the international team competition and won its 18th Fed Cup title last year with Rinaldi in her first season as the captain. The U.S. had not previously won the Fed Cup since 2000.
On the way to the final, the Czechs beat Switzerland 3-1 in the first round and Germany 4-1 in the semifinals.
The final was marred by the absence of top players.
Siniakova was the highest ranked at No. 31.
International Tennis Federation President David Haggerty said in Prague the ITF would like to have more top players in the competition in general.
"One of the concepts is to do something similar to what we've done with the Davis Cup. Nothing is determined (yet)," he said.
Haggerty said the ITF would like to expand the Fed Cup World Group to 16 teams from the current eight because "some of the top players are on the teams that are maybe nine through 16."
