Matteo Berrettini underlined his Wimbledon credentials by beating Filip Krajinovic to claim the Queen's title for a second year in a row.
It is the seventh ATP title of the 26-year-old's career.
Berrettini has now won 20 of his past 21 grass-court matches, with his sole defeat coming against Novak Djokovic in the Wimbledon final last year.
The world number 10 has also claimed back-to-back titles, having beaten Andy Murray to win the Stuttgart Open last week.
By contrast, Krajinovic has lost all five finals he has contested - but he will leave Queen's Club with some positives, having failed to win a main draw ATP match on grass before this week.
