WATCH: Incredible rally headlines Novak Djokovic's Shanghai Masters triumph

It looked like the final of the Shanghai Masters had lost its sheen after Roger Federer's semi-final exit. Many fans would've expected the final to be a block bluster clash between the two tennis heavyweights, Roger Federer and Novak Djokovic. Though, Borna Coric had other plans.

The 13th-seeded Croatian stunned the Swiss ace in straights to book a summit clash with Novak Djokovic. This meant Roger Federer has failed to defend his title after an error-strewn performance. This also meant that it was a major cause of concern for the 20-time Grand Slam champion who besides winning the Australian Open at the start of the year, has had a mediocre campaign by his sky-high standards.

However, the final of the Shanghai Masters didn't fail to disappoint as Borna Coric put up a gritty performance. But, Novak Djokovic was up to the task as he continued his outstanding run of form to dismantle his opponent 6-3, 6-4.

While the final scoreline might not suggest that it was quite an interesting affair. Though, there was one particular moment in the match which left the fans on the edge of their seats with an incredible rally during the first set.

It happened in the fourth game of the opening set when Coric was serving, to level the scores at 2-2. The Croatian and Serbian engaged in an intense battle, with Borna Coric coming out on top. Borna Coric claimed the winner after a down-the-line backhand shot which Djokovic had no chance of reaching.

But after that setback, Novak Djokovic cruised through the game as he raced to his fourth title of the year. With that, the Serbian has been undefeated in 18 ATP matches in a row and with his red-hot form he has added another to his elusive trophy cabinet of titles won this year, which includes the Wimbledon, the Cincinnati Masters, the US Open and now the Shanghai Masters.

The 31-year-old who is the first player to lift all nine Masters titles, will overtake Roger Federer to take the No.2 spot in the ATP rankings, while Rafael Nadal maintains his spot on top of the rankings despite being sidelined with an injury.
