The Czech Republic advanced to the quarter-finals of the Davis Cup after Tomas Berdych overcame the exertions of Saturday to defeat Stanislas Wawrinka in four sets in Geneva.
Less than 24 hours after the players were involved in the longest ever match in the competition's history, Berdych proved much stronger as he ensured the champions' passage with a 6-3 6-4 3-6 7-6 (7-5) victory over his luckless opponent, despite a partizan home crowd.
The 27-year-old Czech star was comparatively untroubled as he took three hours and 15 minutes to secure an unassailable 3-1 lead and book a last-eight meeting with Kazakhstan in April.
Both players were involved in an epic seven-hour doubles contest on Saturday with Wawrinka and his compatriot Marco Chiudinelli eventually beaten 6-4 5-7 6-4 6-7 (3-7) 24-22 by Berdych and his partner Lukas Rosol in a record-breaking match.

Leading 2-1 overnight, Canadian Milos Raonic fired 22 aces in beating Guillermo Garcia-Lopez 6-3 6-4 6-2 to give his side an 3-1 unassailable lead.

The Spaniards were without stars Rafael Nadal, David Ferrer, Fernando Verdasco and Nicolas Almagro.

Serbia lost both of Sunday's dead reverse singles rubbers against Belgium after Novak Djokovic was rested with his nation already through. In the world number one's absence, David Goffin beat Boris Pashanski 6-4 2-6 6-2 while Steve Darcis defeated Nenad Zimonjic 6-2 6-2.
Italy moved into a last-eight tie with Canada after Fabio Fognini defeated Croatia's Ivan Dodig 4-6 6-4 6-4 6-4 in the deciding rubber.

And there was a narrow victory for the United States in the final game to finish as they edged Brazil 3-2 thanks to Sam Querrey's 4-6 6-3 6-4 7-6 victory over Thiago Alves in the final rubber.
Thomaz Bellucci had tied the contest up at 2-2 by battling past big-serving John Isner 2-6 6-4 6-7 6-4 6-3 but Querrey proved to be the US hero.
