JACKSONVILLE, Fla. (AP) -- Brazil's doubles team of Marcelo Melo and Bruno Soares upset the top-ranked Mike and Bob Bryan 7-6 (6), 6-7 (7), 6-4, 3-6, 6-3 and kept the United States from clinching the first-round Davis Cup match.
It was only the third time the Bryan brothers had dropped a Davis Cup match. It was just the second time that they had dropped a five-set match in ATP competition. Their only other five-set defeat was in a 1999 match at Wimbledon.
The United States has a 2-1 advantage heading into Sunday's reverse singles.
CZECH REPUBLIC 2, SWITZERLAND 1
GENEVA (AP) -- In the longest match in Davis Cup history, the Czech Republic beat Switzerland in a doubles epic lasting seven hours.
Tomas Berdych and Lukas Rosol eventually clinched on their 13th match point to edge Stanislas Wawrinka and Marco Chiudinelli 6-4, 5-7, 6-4, 6-7 (3), 24-22.
The defending champion Czechs took a 2-1 lead on Chiudinelli's double-fault.
The previous longest Davis Cup match was 6 hours, 22 minutes for John McEnroe's victory for the United States against Sweden's Mats Wilander in 1982.
Berdych and Wawrinka are due back on court Sunday to begin the reverse singles.
