8. 2017 - Beat Juan Martin del Potro
Following an absence of one year, Federer embarked on his 17th Basel campaign with a straight-sets win over young American Frances Tiafoe. Further victories over Benoît Paire, Adrian Mannarino and David Goffin set up a title showdown with Juan Martin Del Potro, in a rematch of the 2012-13 title matches which had gone the Argentinian's way.
Del Potro took the opening set on a tiebreak. But Federer dispelled the spectre of a third-straight Basel final defeat against the Argentine by taking the next two sets 6-4, 6-3 to seal his 8th Basel title.
It was Federer's seventh title of a fabulous comeback season which saw the Swiss maestro win the Australian Open and Wimbledon titles.

Despite a stern challenge from the Romanian, Federer edged out a tight match in straight sets, 7-6(5) 6-4, to lift the title at his hometown for a ninth time.

The former Basel ball-boy, in his first clash against the young Australian, dished out a tennis lesson, as a 6-2 6-2 victory in over an hour delivered a double-digit title haul at his hometown.
