LONDON — Roger Federer turned on the style to end Novak Djokovic's 23-match winning streak with a 7-5 6-2 defeat of the Serb to book his semi-final berth at the ATP World Tour Finals on Tuesday.
A single break of serve decided a cat-and-mouse opening set, Federer producing a sensational half-volley drop shot in the 12th game having put the Djokovic serve under serious pressure for the first time in the match.
With his Swiss fan club cheering on their man in a packed O2 Arena, the 34-year-old, 17-times grand slam champion pulled ahead in the second set with an early break, only to gift Djokovic the break back with a forehand error.
