Switzerland and the Czech Republic went into the record books on Saturday when they played out the longest match in Davis Cup history, organisers said.
The record was set when the doubles rubber between Stanislas Wawrinka and Marco Chiudinelli and Czech pair Tomas Berdych and Lukas Rosol went to the six hour, 23 minute mark.
"At 6 hours 23 minutes, the Switzerland v Czech Republic doubles match is now the longest match in #DavisCup history! Amazing stuff!," tweeted the organisers.
When the score reached 19-19 in the final set, the clock had ticked to 6 hours 21 minutes, making it the longest doubles rubber ever played in the Davis Cup.
