BASEL, Switzerland – Juan Martin del Potro denied Roger Federer his hometown Swiss Indoors title for the second straight year, winning the final 7-6 (3), 2-6, 6-4 on Sunday.

The top-seeded Argentine clinched the title when Federer could not return a tough forehand.

Federer looked to the home comforts and raucous support at Basel, where he is a five-time champion, to revive his difficult season. He's won just one title in the past 14 months.

Still, the sixth-ranked Swiss star edged closer to securing his place in the eight-man lineup at the ATP World Tour Finals in London starting next week.

Del Potro earned his fourth title this season, all on hard courts.
