Bonzi may only be ranked 124th in the world, but he has had a good run that has led to the first title of his career at the age of 28.

Norrie paid the price for not taking advantage of her opportunities, particularly in a tight first set where she converted just one of 13 break points.

In a mammoth ninth game, the British number two created 10 opportunities on Bonzi’s serve, but was unable to convert any of them and his opponent took the set in a tie-break.

Bonzi, having shown the same resilience he had shown all week, kept the momentum going and broke clinically at the start of the second set.

Norrie’s aggressive return became more fractious as he tried to recover, meaning he was unable to apply any more pressure on Bonzi’s serve.

Serving for the title at 5-4, the Frenchman showed no signs of strain as he hit an ace wide to set up a championship point before sealing the victory.

“I didn’t expect a week like this. It’s crazy to end the year like this,” said Bonzi, who will return to the top 100 in the world next week.

At the Belgrade Open, Canadian Denis Shapovalov also ended a long wait for an ATP title by beating Serbian Hamad Medjedovic in the final.

Shapovalov, 25, has been outside the top 100 for most of the season after a knee injury, but lifted his first trophy since 2019 with a 6-4 6-4 victory.
