Swiss maestro Roger Federer on Sunday came out with a ruthless performance against Alexander Zverev in straight sets to win the men's singles title of the Gerry Weber Open.
Federer defeated fourth seeded Zverev 6-1, 6-3 in the summit clash that lasted less than an hour.
20-year-old Zverev, who had defeated Federer in last year's semi-final, was no match for the Swiss.
The 35-year-old, who had a surprise first-round exit at Stuttgart, was in a superb form as he didn't even lose a set in the entire tournament.
This was the ninth Halle title win for the 18-time Grand Slam champion.
The world number five is among the favourites going into Wimbledon which starts July 2 after sitting out the French Open earlier this month to fine-tune his game.
Federer won the Australian Open - his first Grand Slam success in five years - in January despite not playing in the previous six months. He then claimed the BNP Paribas Open at Indian Wells in March and, two weeks later, the Miami Open.
