Great Britain are one win away from the Davis Cup final after Andy and Jamie Murray beat Australia's Lleyton Hewitt and Sam Groth in the doubles.
The dramatic 4-6 6-3 6-4 6-7 (6-8) 6-4 victory gives Britain a 2-1 lead in the best-of-five tie in Glasgow.
If Andy Murray beats Australian number one Bernard Tomic in Sunday's opening reverse singles, Britain will be through to a first final since 1978.
Belgium are 1-1 against Argentina in the other World Group semi-final.
