LONDON (Reuters) - Novak Djokovic has left the chasing pack breathing in his fumes this season but he spluttered at the ATP World Tour Finals on Tuesday as Roger Federer ended his 23-match winning streak with a 7-5 6-2 group stage victory.
The world number one would probably have beaten most players, even with the errors piling up and his serve out of sync, but not Swiss great Federer who sealed a semi-final spot with a match to spare.
Federer has now been responsible for three of Djokovic's six defeats this season, edging ahead 22-21 in their career rivalry.
Djokovic's first indoor loss since 2012, in which time he has won three consecutive London year-enders, means he needs to beat Czech Tomas Berdych on Thursday to be sure of joining Federer in the semi-finals.

Djokovic could even scramble through with a three-set defeat, providing Nishikori does not win.
