| "A year that I won most matches does carry some significance 
				but what is important is how much I can win at big tournaments," 
				the 2014 U.S. Open runner-up was quoted as saying by Kyodo news 
				agency.
 "Result-wise this has been my best year. I've played well 
				against the top-10 players and have been winning against the 
				likes of (Rafa) Nadal and (Andy) Murray, who I couldn't beat 
				before.
 
 "I'm making fewer mistakes as I get older. I hope to keep 
				building, bit-by-bit."
 
 Nishikori started the campaign by reaching the quarter-finals of 
				the Australian Open and followed that up by winning his only 
				title of the year at the Memphis Open.
 
 His form faltered slightly with fourth round defeats at the 
				French Open and Wimbledon, before he rediscovered his touch to 
				win bronze at the Rio Olympics and reached the semi-finals of 
				the U.S. Open, losing to eventual champion Stan Wawrinka.
 
 Nishikori was also a losing finalist at the Miami Open in April 
				and Rogers Cup in July before his season ended with a defeat to 
				Novak Djokovic in the semi-finals of the ATP World Tour Finals 
				in London on Saturday.
 
 The 26-year-old remains hopeful he can climb up to number three 
				in the world rankings, one better than his career-high.
 
 "I'm confident I have the ability to challenge for world number 
				three and four," he added.
 
 "I need to be more cautious while determining which points in 
				the match I have to focus and how I can win break points in a 
				more assured manner."
