It was a different Roger Federer than the one people saw on the first day against Gael Monfils. He looked fitter and more enthusiastic as he combined with Stanislas Wawrinka in the doubles tie on Saturday. The two guys don’t play much doubles together but they justified the confidence reposed in them by their captain. Despite Federer’s poor show against Monfils, Severin Luthi persisted with pairing the world no.2 with Wawrinka in the doubles, instead of the nominated Marco Chiudinelli and Michael Lammer. Luthi’s move paid rich dividends
