Andy Murray has the chance to put Great Britain in the last eight of the Davis Cup by defeating American John Isner in their singles match in Glasgow on Sunday.
Great Britain take a 2-1 lead into the final day of the best-of-five match against the United States after a thrilling doubles match went the way of the Americans on Saturday.
Jamie Murray and Dom Inglot were defeated in a marathon doubles encounter by American world number one pairing Bob and Mike Bryan 6-3 6-2 3-6 6-7 (8-10) 9-7 in three hours and 37 minutes.
It means that Andy Murray will have the chance to seal a quarter-final meeting with France in front of a raucous Glasgow crowd on Sunday.
Team GB captain Leon Smith is taking nothing for granted ahead of Murray’s clash with the big-serving world number 20.
“It is going to be a tough, tough test,” Smith said. “He’s pushed Andy before, he’s going to serve well against anyone – even one of the best returners in the world – and if he gets to a breaker and catches fire with one return, it’s difficult.”
Murray is a strong 1.07 favourite to defeat Isner (8.17) and claim the decisive point for Great Britain.
American captain Jim Courier says Isner is ready for the task at hand.
“He’s good,” said Courier. “He was well prepared that he’s going to be playing on Sunday, that these guys (the Bryans) were likely to win. He should be ready.”
Victory for Isner would set up a decider between Team GB’s James Ward (2.35) and Donald Young (1.60).
