Andy Murray defeated Bernard Tomic to guide Great Britain into a first Davis Cup final since 1978 after taking an unassailable lead over Australia in Glasgow. Murray maintained his 100% record over Tomic by prevailing 7-5 6-3 6-2 to set up a final against either Belgium or Argentina.

Murray had played on the first two days of competition, beating Thanasi Kokkinakis in the singles and combining with brother Jamie to defeat Sam Groth and Lleyton Hewitt in the doubles and said he was feeling jaded ahead of the fourth rubber of the match. But the Briton showed few signs of being leg-weary and dispatched the Aussie protege in three sets.

Victory puts Britain into the final in November with the chance of ending 79 years without winning the Davis Cup. The GB team in 1936 included the likes Bunny Austin, Fred Perry, Patrick Hughes and Raymond Tuckey and Murray and co. have the chance to join those illustrious names.
