Tomas Berdych and Lukas Rosol enjoyed a taste of Davis Cup history on Saturday, when they won the longest match played in the competition.
The Czech Republic pair needed seven hours and two minutes to beat Switzerland's Stanislas Wawrinka and Marco Chiudinelli in five sets and edge the defending champions 2-1 ahead in their World Group contest in Geneva.
Berdych and Rosol - who beat Rafael Nadal at Wimbledon last year - needed 13 match points to register their 6-4 5-7 6-4 6-7 (7-3) 24-22 triumph on the indoor court.
The enthralling contest yielded 51 aces - 28 of these to the eventual losers - and 19 double faults.
The Czechs converted four of their 24 break point opportunities and needed to win 299 points before sealing a famous victory - the Swiss duo won 290.
The previous longest match in the event's 113-year history came in 1982 when American John McEnroe was on court for six hours and 22 minutes, before beating 17-year-old Swede Mats Wilander in St Louis, Missouri.
As for the Czechs and Swiss, Berdych and Wawrinka are due back on court at Sunday lunchtime for their second singles match.
