Roger Federer claimed his seventh Gerry Weber Open title on Sunday with a hard-fought 7-6 (7/2) 7-6 (7/3) win over Colombian Alejandro Falla.
The Swiss made it through to his ninth final in 12 years at the German venue after dispatching Kei Nishikori, the fourth seed.
Falla, meanwhile, was in search of a first title on the ATP tour, having come from a set down to beat local favourite Philipp Kohlschreiber in their semi-final.
Federer, 32, went into Sunday's showdown holding a 6-0 record over the Colombian.
However, having been two-sets down against Falla in the first round of Wimbledon four years ago, there would be no complacency from the Swiss against the world number 69.
The first set proved a tight affair, although Federer missed the chance to close out on serve at 5-3, only for Falla to break back and eventually force the tie break.
Federer, though, did not waste another opportunity when he claimed five straight points from 2-2 to take the first set in 42 minutes.
Falla, 30, continued to push Federer as there remained little margin for error in the second set, which also went locked at 6-6.
Federer forced an early mini-break on the first point and then took control at 3-0 when he came to the net to drive down a forehand.
The Swiss world number four remained in charge at 5-2 when he crashed in another big serve.
A wide passing shot down the line from Falla, which was upheld on review, handed three match points to Federer and t he Swiss took the opportunity at the first time of asking to secure a 14th grass-court title.
Later on Sunday, Federer will also contest the doubles final, alongside compatriot Marco Chiudinelli when they face German Andre Begemann and Austria's Julian Knowle.
Despite the disappointment of defeat in the fourth round at the French Open, Federer will be heading to Wimbledon looking for an eighth title at the All England Club - which would see the Swiss player eclipse Pete Sampras' post-open-era record.
