GHENT, Belgium -- Britain is one point away from lifting the Davis Cup title for the first time in 79 years after winning the doubles against Belgium on Saturday.
Brothers Andy and Jamie Murray beat David Goffin and Steve Darcis 6-4, 4-6, 6-3, 6-2 to give Britain a 2-1 lead in the final going into the reverse singles on Sunday.
Andy Murray could seal Britain's victory in Sunday's first match against Goffin.
The brothers fought off seven break points in the key fourth game of the fourth set and cruised from that point as the Belgian spirit sagged. The British pair broke serve one more time and Andy Murray fired a service winner on their second match point to put it away.
The teams split the opening singles on Friday.
Goffin and Darcis had never played together in a tie before, while the Murray brothers improved to 4-0 in the competition.
At the end of the first set, the brothers played a pair of good volleys to make it deuce. With Goffin serving, Darcis hit an overhead smash wide and the Britons gained a set point. Andy Murray swapped volleys with Goffin, before the Belgian hit the net to give the set to Britain.
With the set under the belt, Andy Murray jumped wildly up and down, clenching his fist and pointing it at British supporters.
A double fault by Jamie Murray gave the Belgians their third break point and they used it when Goffin fired a volley winner for a 2-1 lead in the second.
Darcis held serve in the sixth game, having saved a break point with a service winner before Goffin hit a perfect lob to clinch the game.
Goffin also clinched the second set, hitting an off-balance volley while bending down and with his racket next to his shoulder. But the unorthodox shot was a winner, and Belgium was back in the match.
The Belgians gained the first break in the third set. Darcis set it up with a passing shot past Jamie Murray, and Goffin finished it off by returning Jamie Murray's serve down the line.
But it was break back for Britain in the next game, with Jamie Murray hitting a crisp volley to the body of Goffin.
Britain got on top when a line judge was overruled and the point, given initially to Belgium, was replayed. Two Belgian errors followed and the brothers were 4-2 up.
With sloppy play on both sides, the third set saw five breaks of serve before Andy Murray closed it out with a service winner.
Some of the best tennis came in the second game of the fourth, with Britain recovering from a 0-30 deficit. Andy Murray fired consecutive service winners to make it 1-1 despite some inspired play by the Belgians.
The break came in the next game following a double fault by Darcis and a volley error by Goffin.
Then came the decisive game with the Britons saving seven break points.
