Andy Murray revealed he battled through a back injury to propel Great Britain into their first Davis Cup final for 37 years.
Despite being less than 100 per cent fit, Murray managed to find another peak performance in his second straight-sets singles win of the semi-final against Australia by beating Bernard Tomic 7-5 6-3 6-2 in Glasgow.
That, coupled with Murray’s win over Thanasi Kokkinakis on Friday and his doubles triumph with brother Jamie, gave Leon Smith’s team an unassailable lead and the chance to win the competition for the first time since 1936.
Kokkinakis later beat Dan Evans 7-5 6-4 to ensure a 3-2 win for Britain, which sets up a final meeting away to Belgium on November 27-29, following their 3-2 triumph over Argentina in Brussels.
Murray did not appear to be moving too freely early in the four-hour doubles win on Saturday, but he gave nothing away on his injury until after the triumph was sealed.
The world number three, who had back surgery two years ago, said: “I wasn’t concerned about how much I had left in the tank, I was more concerned about my back. My back has been giving me a lot of trouble this week.
“It’s nothing to do with the previous issues I had with my back, it’s a completely different thing.”
