Halle was his first tournament since becoming the World No. 1.
The 22-year-old defeated his doubles partner Hubert Hurkacz 7-6(8), 7-6(2) to lift the ATP 500 trophy.
“I’m just looking forward to it,” the Australian Open champion said, referring to Wimbledon.
“Last year I made the semis, I played some good tennis.
“So, let’s see what’s coming this year.
“I’m more confident for sure.
“And on this surface, obviously the grass might be a bit different between here and Wimbledon.
“But I have one week now to prepare for it, so hopefully it’s going to be a good tournament.”
Sinner’s compatriots Simone Bolelli and Andrea Vavassori beat Kevin Krawietz and Tim Puetz 7-6(3), 7-6(5) to take the men’s doubles title in Halle.
The pair continued their impressive form after they reached the finals of the Australian Open and Roland Garros.
But Lorenzo Musetti lost 6-1, 7-6(8) to American Tommy Paul in the final at Queen’s.
