Judd Trump beat China's Si Jiahui 10-5 to win a record third German Masters title.
The Englishman won five frames out of six in Sunday's evening session to claim the 27th ranking event of his career.
Trump, 34, showed his experience to ease away from 21-year-old Si, who was in his first ranking final.
"It's been an amazing season so far," said 2019 world champion Trump, after his fourth win from seven finals.
"Every tournament is special when you get to play in front of a crowd like this and lift the trophy, it's something you remember for the rest of your career."
Si threatened an upset in Berlin after narrowing the gap to 5-4 with a 123 break in the first frame of the evening, rekindling the form that took him to the World Championship semi-finals last season.
But Trump eased any nerves by replying with two century breaks of his own.
He made runs of 113 and 108 in the 10th and 11th frames, and reeled off three of the next four frames with breaks of more than 50 to seal a comfortable victory.
The world number two tops this season's prize money list after also winning the English Open, Wuhan Open and Northern Ireland Open.
