Roger Federer won the Gerry Weber open for the seventh time by defeating Alejandro Falla 7-6 (2), 7-6 (3) in the final on Sunday.
Federer fired five aces and saved three of the five break points he faced to win in 1 hour, 28 minutes. It was the 32-year-old's 14th title on grass and 79th overall.
The seven-time Wimbledon champion improved his record to 46-5 in 12 appearances at the tournament where he made his debut 14 years ago.
It was also Federer's seventh win from seven meetings with Falla.
The 69th-ranked Falla was the first Colombian to reach the final of a grass-court tournament. He was playing his second on tour after he finished runner-up to Ivo Karlovic at Bogota in 2013.
