Djokovic beats Nishikori to reach final in London

LONDON (AP) — Two-time defending champion Novak Djokovic overcame a lapse of concentration to beat Kei Nishikori 6-1, 3-6, 6-0 and advance to a third straight final at the ATP Finals on Saturday.

The Serb, who sealed the year-end No. 1 spot after finishing unbeaten in the round robin phase, dropped his first set since the start of the tournament after losing his focus early in the second set, visibly angered by a partisan crowd.

Nishikori failed to build on the momentum at the start of the decider when he missed two break points before Djokovic recovered and won the last six games.

Djokovic will next face either Roger Federer or Stan Wawrinka, who played later in an all-Swiss semifinal.
