I had a match point and Andrey hit an amazing serve and then he had a match point and then I had some match points."
Rublev broke Hurkacz's serve early in the second set but it was in the final set where the match really came to life.
Rublev steadied himself to save match point and hold serve, and in the tiebreak he snatched early control to take a 3-0 lead.
Two aces from the Polish player kept him in touch and at 5-6 down he served another ace to save match point.
Both players broke serve again in quick succession to level the tiebreak at 8-8, but it was Hurkacz who had the last word and broke Rublev's serve again to win the title.
