LILLE, France, Sept 16 (Reuters) - France took a 2-1 lead at home to Serbia in their Davis Cup semi-final when Pierre-Hugues Herbert and Nicolas Mahut beat Filip Krajinovic and Nenad Zimonjic 6-1 6-2 7-6(3) in the doubles on Saturday.
Herbert and Mahut, who together have won two grand slam doubles titles, lost only two points on serve in the first set and were barely troubled in a one-sided match on indoor clay at Pierre Mauroy stadium.
They did lose their focus in the third set after opening a 5-2 lead, but they played a near perfect tiebreak to seal the win on their first match point.
Serbia took the first point in the tie when Dusan Lajovic beat Lucas Pouille in four sets before Jo-Wilfried Tsonga levelled it up by beating Laslo Djere in straight sets.
Tsonga is set to face Lajovic in a potentially decisive reverse singles rubber on Sunday.
