BASEL (Reuters) - World number one Roger Federer missed out on a fourth successive Swiss Indoors title when he lost to third-ranked Novak Djokovic in the final on Sunday.

The Serbian won 6-4 4-6 6-2 to record his third win over Federer in five meetings this year.

Federer, who had not dropped a set or lost a service game on his way to the final, had his serve broken four times as he lost a final for the third time this year, following defeats at the Australian and U.S. Open.

The match featured an extraordinary 10th game in the first set where Federer saved six set points and Djokovic saved five break points before the Serbian wrapped up the game at the seventh attempt.
