Defending champions the Czech Republic and Switzerland slogged it out to set a new record for the longest Davis Cup match in history.
Tomas Berdych and Lukas Rosol took seven hours and two minutes to see off Swiss pair Stanislas Wawrinka and Marco Chiudinelli in a doubles rubber.
The world group first-round match was settled on a double fault, finishing 6-4 5-7 6-4 6-7 24-22.
Berdych said: "I have never played tennis that long."
He added: "I like it because I now have a new experience but we still need one more point, so let's go again Sunday."
The previous match record was six hours and 22 minutes.
That was held by American John McEnroe's 9-7 6-2 15-17 3-6 8-6 win over Sweden's Mats Wilander in 1982 before tie-breaks were contested.
Berdych and Rosol's doubles victory is now the second longest match ever behind American
John Isner's 6-4 3-6 6-7 7-6 70-68 win against Frenchman Nicolas Mahut
in the first round of Wimbledon in 2010.
That match was played over three days and the pair spent 11 hours and five minutes on court.
