Andy and Jamie Murray combined superbly in Saturday's doubles as Great Britain moved 2-1 ahead in the Davis Cup final with Belgium.

The brothers overcame mix-ups early on to put the visitors on the verge of their first title since 1936 as they beat Steve Darcis and David Goffin 6-4 4-6 6-3 6-2.

Andy Murray again led the way in Ghent, the younger brother coming to the fore when his sibling was under pressure with his serve.

It fell to Jamie Murray to serve out for victory and he held his nerve well, ably assisted by some controlled volleying from Andy Murray at the net.

Once they settled into the contest Great Britain found their rhythm, but took their time to find any openings, the match going with serve in the opening nine games.

Darcis and Goffin – roared on by the partisan home crowd – were executing some crashing cross-court forehands and eventually that gave them the first break-point chance on Andy Murray's serve.

That was saved with a well-placed ace from the world number two, before the Murray brothers finally found a way through as Goffin faltered.

Great Britain were unable to build on that, though, as Jamie Murray came under pressure, the doubles specialist buckling after saving two break points.

That was enough for Belgium to go on and level, with Goffin particularly impressing with some devastating forehands from the baseline.

After two tight sets, the third was littered with breaks, Great Britain slightly edging it as they moved 5-3 ahead thanks to a weak service game from Darcis.

Presented with a chance to restore Great Britain's lead, Andy Murray was able to handle the pressure on his shoulders and produce a towering serve to make it 2-1.

With victory in sight the visitors applied pressure on Darcis and once again he succumbed, a double fault and volley into the net bringing fist pumps from the opposite side of the court.

An eight-minute service game from Jamie Murray and second break of the Darcis serve gave Great Britain their chance of victory and they quickly wrapped things up to move ahead in the final.

Great Britain coach Leon Smith will now hope Andy Murray can secure the win when he plays Goffin in Sunday's first singles match.
