Roger Federer has won his seventh Gerry Weber Open in Halle, beating Alejandro Falla 7-6 (7-2) 7-6 (7-3).
Switzerland's Federer, the number two seed, was winning his 14th title on grass and 79th overall with his victory against Colombian Falla in Germany.
It is the second title of 2014 for the 32-year-old who will attempt to secure an eighth crown at Wimbledon which starts on Monday, 23 June.
Four of Federer's Wimbledon wins have come after claiming the Halle title.
Defending the only title he won in 2013, Federer triumphed in one hour 28 minutes.
Although he missed the chance to close out the first set on serve at 5-3, he claimed five straight points from 2-2 in the tie-break.
The second set also went to a tie-break where Federer took control after forcing a mini-break on the first point.
Falla, 30, ranked 69, was seeking his first tour title.
Federer - who earlier this month failed to reach the French Open quarter-finals for the first time since 2004 - had won their previous six meetings, though Falla had served for the match when they met in the Wimbledon first round in 2010, before the Swiss eventually prevailed in five sets.
Later on Sunday, Federer will contest the doubles final in Halle alongside compatriot Marco Chiudinelli, when they face German Andre Begemann and Austria's Julian Knowle.
