Jeremy Chardy, Marco Cecchinato, Kevin Anderson and Sascha Zverev were all dismissed in straight sets, before Djokovic navigated past a spirited Borna Coric 6-3 6-4 to land a fourth Shanghai Masters crown.
Three or four terrific months
Back to his all-conquering best, Djokovic has a real opportunity to usurp Rafael Nadal to finish the season as the year end No.1, something he achieved in 2011, 12, 14 and 15.
“It's phenomenal. I'm very proud of it," stated Djokovic, having surged just 215 points behind Nadal in the rankings.
"Obviously the last three, four months have been terrific for me. Not many holes in the game in general, especially this week. Everything worked perfectly.
“Taking the No.1 ranking at the end of the season would be my best achievement this year.”
Should the Wimbledon and US Open champion return top of the rankings, Djokovic would be the first player to launch from outside the Top 20 to finish No.1 in history.
