SAN DIEGO - Wimbledon champion Andy Murray beat Sam Querrey 7-6 (5), 6-7 (3), 6-1, 6-3 to clinch Great Britain's opening-round Davis Cup victory against the United States on Sunday at Petco Park.
Murray won his 18th straight Davis Cup singles match and Great Britain beat the Americans for the first time since 1935.
Britain advanced to the World Group quarterfinals for the first time since 1986. It will face Italy, which defeated Argentina.
Murray split tiebreakers with Querrey in the first two sets, breezed through the third set in 29 minutes and won the match when Querrey returned a serve long.
Murray leaned back and pumped both fists in the corner of the court and eventually joined his teammates in celebration.
Britain beat the United States 3-1.
