Kei Nishikori has admitted that Marin Cilic proved too good for him in the US Open final on Monday.
The Japanese suffered a straight-sets defeat to the Croatian in under two hours at Flushing Meadows.
Nishikori has conceded that there was little that he could do to stop the big-serving Cilic on this occasion and is simply content with having reached his first Grand Slam final.
He told reporters: "He was playing really well today, I couldn't play my tennis. It's a really tough loss but I'm really happy for first coming to the final."
The 24-year-old beat Milos Raonic, Stanislas Wawrinka and Novak Djokovic on his way to the final.
