Djokovic will replace Roger Federer as world number two on Monday after claiming a third successive title and is only 35 points behind Nadal.
There was no let-up, though, and a sublime volley had Djokovic cupping an ear to the crowd as Coric failed to break back, the contest finally settled as the 14-time grand slam victor served out the championship.
This accounted for the 95-minute match at the end of which Djokovic had won 72 of the total 124 points played while Coric tallied 52.Djokovic's fourth title in Shanghai added to his victories over Andy Murray in 2012, Del Potro in 2013 and Jo-Wilfried Tsonga in 2015.
After months of recovery from elbow surgery and a drop in his level of play that sent him tumbling down the rankings, Djokovic has recovered in the second half of the year to win titles at Wimbledon, the US Open and the Cincinnati Masters and now Shanghai. "The last three or four months have been phenomenal in terms of the quality of tennis", Djokovic said.
"This was definitely one of the best service weeks that I've had in my career", Djokovic said.
Djokovic said he felt that the Chinese fans were really behind him and he always liked to come back to Shanghai for this reason. It's all very, very positive, for more than 10 years that I have been coming to China. With his win over Coric in the Final, Djokovic now moves up a spot in the rankings to No. 2, taking the position away from Federer who falls to No. 3.
Commenting on it, the world No. 13 stated: 'I have been really working hard through the whole of my career. I think I can learn a lot from this match.
Coric, who had his right thigh wrapped throughout the match, saved three match points on his own serve in the ninth game of the second set.
