The 25-year-old Ćorić, who currently ranks 152nd, has thus become the lowest ranking tennis player to win a Masters 1000 tournament.
This has been the second final in a Masters 1000 tournament for this Croatian player born in Zagreb.
Four years ago he reached the final of the ATP Masters 1000 Shanghai, where he was defeated by Serbia’s Novak Đoković.
Ćorić’s career high was the 12th place on the ATP rankings in 2018.
