Andy Murray will partner brother Jamie in Great Britain’s pivotal Davis Cup doubles rubber against Australians Lleyton Hewitt and Sam Groth.

British captain Leon Smith had named Dom Inglot to partner Jamie Murray, but made the change with the semi-final tie in Glasgow deadlocked at one match apiece after Friday’s opening singles rubbers.

The winners of the best-of-five-match tie will face with Argentina or Belgium in this year’s Davis Cup final.
