Nicolas Mahut and Pierre-Hugues Herbert

France kept their Davis Cup final hopes alive on Saturday as Nicolas Mahut and Pierre-Hugues Herbert beat the Croatian pair of Ivan Dodig and Mate Pavic 6-4 6-4 3-6 7-6(3).

In a tense doubles battle in the Stade Pierre Mauroy at Lille, Yannick Noah’s champions had their backs against the wall after losing both Friday’s singles.

But Herbert and Mahut began the fightback, reducing the deficit to 2-1 and ensuring the last Davis Cup in its present guise will stretch into Sunday.

The odds are still stacked in Croatia’s favor as no team has recovered from 0-2 down to win the trophy since Australia beat the US in 1939.

But with 26,000 mainly flag-waving French fans set to flock back into the cavernous home of Lille’s football club on Sunday, hope still remains.

It had looked like being a relatively comfortable win for the French duo when they had points for a double break in the third set.

They had won the first two in dominant fashion.

But Pavic and Dodig hit back to set home nerves jangling.

Dodig had partnered Marin Cilic to a crucial win over Mahut and Herbert when the sides met in the 2016 semi-finals in Zadar.

Herbert faltered when serving at 3-4, allowing the Croats to break serve and then hold with ease to the delight of their noisy followers high in the upper tiers.

Alarm bells were ringing at the start of the fourth when France had to save three break points on the Herbert serve.

He was again made to work hard at 2-2 as the momentum of the match began to swing Croatia’s way.

France kept their noses in front though and the fans ratcheted up the decibel levels as Pavic served at 4-5.

Pavic, yet to win a Davis Cup tie, duly buckled with a double-fault at 0-30 and bedlam broke out in the stands with opposing fan clubs trying to out-sing each other.

With the umpire struggling to restore order, Pavic showed incredible composure as he and Dodig somehow dug themselves out of a seemingly impossible position to make it 5-5.

Boos rang out as Pavic gestured defiantly at the massed ranks of blue amid the suspicion that Croatia would be favorites to win the rubber if they could take the tiebreak.

Yet Mahut and Herbert jumped into a 4-1 lead and, though the Croatians got it back to 4-3, the pair then kept their cool with Mahut’s reflex volley sealing the win.
