The leading lights of tennis' next generation of stars battled it out for well over three hours in Beijing on Wednesday before Alcaraz finally prevailed 6-7 (6-8) 6-4 7-6 (7-3).
Having cruised into a 5-2 lead in the opening set, Alcaraz wobbled to allow defending champion Sinner to reel off four of the next five games to force a tie-break that the Italian won with three breaks of serve.
An hour-long second set was settled in Alcaraz's favour, but a topsy-turvy decider went the distance.
Having given up the first break, Sinner responded by hitting back in game eight to restore parity, with another tie-break required.
Sinner breezed into a 3-0 lead, only for Alcaraz to string together an extraordinary run of seven straight points to claim the crown.

It is now 6-4 to Alcaraz in the head-to-head between the Spaniard and Sinner.
Alcaraz has now won all three of their matches this season, triumphing previously at both Indian Wells and Roland-Garros. It is the first time either of the duo has won three straight matches against the other.
At the age of 21 years and 150 days, Alcaraz is the youngest player to defeat the world number one in an ATP event final after losing the opening set since Juan Martin del Potro (20y 356d), who came back to beat Roger Federer at the US Open in 2009.
