Paris: Roger Federer will team up with Stan Wawrinka in the doubles contest at the Davis Cup final against France in Lille on Saturday.
The Swiss pair will go up against French duo of Richard Gasquet and Julien Benneteau. The 17-time Grand Slam champion Federer was badly beaten in three sets by Gael Monfils in the opening singles on Friday, while Wawrinka beat Jo-Wilfried Tsonga in four.
But after the defeat Federer said that the back injury that struck him last weekend in London was on the mend and he made himself available for doubles and singles.
Swiss captain Severin Luthi opted to go with his two top players - Olympic doubles champions in Beijing in 2008, but who have lost their last four Davis Cup doubles outings.
The problem for the Swiss is that the two other players in the team -- Marco Chiudinelli and Michael Lammer -- are ranked 206th and 508th in the world.
French captain Arnaud Clement had been expected to ask Tsonga to partner Gasquet, but instead went with the Benneteau-Gasquet pairing.
