The 21-year-old produced a serving masterclass to deny his opponent any break points in the 73-minute triumph.
If Coric wins Sunday’s showdown, he will have beaten all of the ‘Big Four’: Djokovic, Federer, Rafael Nadal and Andy Murray.
Earlier, Djokovic extended his unbeaten run to 17 matches on Saturday after beating Alexander Zverev 6-2 6-1 in the Shanghai Masters.

The win means that Djokovic will return to No.2 in the ATP world rankings when they are published later this month, with the possibility of reclaiming his No.1 sport now in sight.
In his 1000th tour-level match, the 31-year-old saw off competition from Zverev in just an hour and 19 seconds.
Though Zverev had been on course to become the only man to record 50 tour-level victories this season, he was no match for the Serbian, who covered the court well and put the youngster under relentless pressure.
