Juan Martín del Potro played the role of spoiler at the Swiss Indoors Basel to add another title to his count…

The 24-year-old Argentine tenista beat hometown favorite Roger Federer in the finals on Sunday, 6-4, 6-7 (5), 7-6 (3) to claim his fourth title of the year.

Del Potro demonstrated a remarkable all-around game to avenge a heartbreaking loss to Federer in the 2012 Olympic Games semifinals in August.

“It was an unbelievable final,” said del Potro, who never dropped serve and raised his game in the decisive tiebreaker. “You can’t wait, you have to go to (get) the victory.”

Federer, who won the event in five of the past six years, was seeking his 77th career title to tie John McEnroe at fourth on the Open Era list.

“I didn’t play a good tiebreaker in the third and that was the story of the match,” said Federer, offering generous praise to his opponent. “I definitely think he is right there again.”

Del Potro ended a six-match losing streak against the top-ranked Swiss player this year, which included a five-set defeat at the French Open.

“This time it was for me,” said del Potro, who improved to 3-13 lifetime against Federer. The first of those victories was in the 2009 U.S. Open.

del Potro won for the second straight week after taking the Vienna title. It’s the 13th title of his career. He will likely remain No. 8 in the world when the rankings are updated Monday.
