Djokovic to play Fish in title clash

Tsonga's retirement with an injured forearm provided a shock ending to their mouth-watering Wimbledon semifinal rematch, but the Frenchman's surrender in the face of the Djokovic juggernaut seemed almost predictable.

Djokovic will now take on in-form American Mardy Fish in Sunday's final and have the chance to become the first to capture five Masters series titles in a single season.Fish swept past Serb Janko Tipsarevic 6-3, 6-4.
