LILLE, France -- Two-time Grand Slam champions Nicolas Mahut and Pierre-Hugues Herbert beat Filip Krajinovic and Nenad Zimonjic 6-1, 6-2, 7-6 (3) to give France a 2-1 lead over Serbia in the Davis Cup semifinals on Saturday.
Apart from a scare in the third set when the Serb pair won four games in a row, Mahut and Herbert were in control on the indoor clay court and put France one win away from its 18th Davis Cup final.
"We are super happy and very proud," said Herbert, who won both Wimbledon and the U.S Open with Mahut. "It's never easy to serve for the match, I felt weaker at the worst time."
The French had been flawless on their service games until 5-2 in the third set when Herbert was broken after he hit a double fault. The Serbian duo broke again following two beautiful winners from Krajinovic -- a perfect lob and passing shot -- but the French proved stronger in the tiebreaker.
Mahut, who has been hampered by a calf injury in recent weeks, thanked the medical staff for enabling him to play.
"They did not count their hours to put me back on my feet," he said. "This victory is also theirs."
Friday's singles rubbers had been played on outdoor clay but organizers decided to close the roof at the Pierre Mauroy stadium in the northern city of Lille because of forecasts of bad weather.
In the other semifinal, Australia took command of their Davis Cup match against Belgium on Saturday as doubles pair John Peers and Jordan Thompson cruised to a straight sets win in Brussels.
Peers and Thompson beat home pair Ruben Bemelmans and Arthur de Greef 6-3 6-4 6-0 to give Australia a 2-1 lead heading into Sunday's decisive reverse singles.
The Australian pair dominated proceedings, claiming victory in just over 90 minutes and boosting their nation's quest for a first Davis Cup title since 2003.
Sunday's action will see the unpredictable Nick Kyrgios -- who came from behind to clinch a crucial win over Steve Darcis on Saturday -- face Belgian No.1 David Goffin. Victory for Kyrgios will be enough for the Australians but if Goffin is successful the tie will come down to a match between John Millman and the higher-ranked Darcis.
