San Diego: Andy Murray beat Sam Querrey in four sets late on Sunday night to send Great Britain into the quarter-finals of the Davis Cup for the first time since 1986.

Wimbledon champion Murray posted his second singles victory of the tie, downing Querrey 7-6 (7/5), 6-7 (3/7), 6-1, 6-3 to capture the needed third point in a 3-1 victory in the best-of-five match tie.
Britain had seized a commanding 2-0 lead on the opening day on Friday as 175th-ranked James Ward pulled off a remarkable comeback win over Querrey.
Ward won 10 of the last 11 games to grab the five-set triumph, after Murray had crushed Davis Cup newcomer Donald Young in straight sets.
Young was a late replacement in the US squad for injured John Isner. The formidable doubles duo of Bob and Mike Bryan had kept the Americans alive with a doubles victory over Colin Fleming and Dominic Inglot on Saturday.
However, Querrey couldn't prevent Great Britain from posting their first Davis Cup win over the United States since 1935.
