Great Britain captain Leon Smith has insisted that he made the right decision in selecting Andy Murray ahead of Dom Inglot for his side's Davis Cup doubles match against Australia.

Murray and his brother Jamie defeated Lleyton Hewitt and Sam Groth in a five-set thriller to move Team GB one win away from the Davis Cup final after Smith opted to play world number three ahead of Inglot.

"Andy is the best player across both teams and if he can play, he should play," Smith told BBC Sport.

"Not only that, Andy and Jamie together are a great pair and what they did against France was absolutely outstanding, and they've done it again today. I think it was the right decision."

Britain will advance to the Davis Cup final if Andy Murray defeats Bernard Tomic in their singles match later today.
