Djokovic books place in semis

Novak Djokovic completed a blockbuster semi-final line-up at the Barclays ATP World Tour Finals with a routine 6-2 6-3 victory over a lacklustre Andy Roddick tonight.

The Serb will play Group B winner Roger Federer while world number one Rafael Nadal, who beat Tomas Berdych 7-6 (7/3) 6-1 earlier today to ensure top spot in Group A, faces Andy Murray.
