A great season for Kei Nishikori came to a disappointing finish on Saturday, when he was knocked out of the ATP World Tour Finals by world No. 2 Novak Djokovic.

Nishikori, ranked fifth in the world, lost their semifinal match 6-1, 6-1 in 1 hour, 6 minutes. Djokovic will take on top-ranked Briton Andy Murray in Sunday's final after Murray scraped past Canada's Milos Raonic 5-7, 7-6 (7-5), 7-6 (11-9).

"Today I think Novak played pretty awesome," said Nishikori who played a three-set match late on Friday night. "But I wasn't ready to play against Novak, physically. I tried to play good tennis, but I couldn't today. I did play well at times, but he was too strong.
