LONDON: Roger Federer ended Novak Djokovic’s 23-match winning streak with a 7-5 6-2 group stage victory to secure a semi-final place at the ATP World Tour Finals.
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.
