GLASGOW, March 7, 2015 (AFP) - Bob and Mike Bryan kept the United States in with a chance of a dramatic Davis Cup fightback as they held off a strong challenge from Great Britain's Jamie Murray and Dom Inglot to win 6-3, 6-2, 3-6, 6-7 (8/10), 9-7 on Saturday.
Faced with a 2-0 deficit after Friday's singles matches, the Bryan brothers knew another loss would condemn the US to an embarrassingly quick defeat in Glasgow.
The world's number one doubles team got the job done, but not without a scare as Murray, the brother of Davis Cup team-mate Andy Murray, and Inglot recovered from two sets down.
The hosts' hopes of a comeback to match James Ward's epic triumph against John Isner - the Briton had won 15-13 in the final set on Friday after losing the first two sets - were eventually snuffed out as the Bryans secured a win that sets up an intriguing final day of singles action on Sunday.
Former Wimbledon and US Open champion Andy Murray can clinch the tie for Britain if he defeats Isner in the opening match of the day, but a defeat for the Scot would leave Ward and Donald Young to clash in the deciding rubber.
The Bryans, who have won 16 grand slam titles and Olympic gold together, were the clear favourites against a pair that had not been matched up since a junior tournament in 2003.
They looked certain to cruise to victory after winning the first two sets with the minimum fuss.
But the momentum changed when Jamie Murray smashed a volley to break Mike Bryan's serve in a third set which the Britons took emphatically.
Murray's positive serving forced a fourth set tiebreak and Inglot produced three powerful volleys at the net to turn a 5-3 deficit into an set point.
That went begging and the home pair soon faced match point but Inglot's powerful return proved too good for Bob Bryan and Murray secured two points in a row to force a decider.
The deciding set was evenly poised and Murray saved a break point at 7-7 with an ace, but the Bryans forced another one and this time the Scot volleyed into the net before the Americans finally sealed the win.
