BASEL, Switzerland (AP) — Juan Martin del Potro took Roger Federer's Swiss Indoors title on Sunday, beating the hometown favorite 6-4, 6-7 (5), 7-6 (3) in the final.
Del Potro showed an impressive all-around game to help avenge a heartbreaking loss to Federer in the Olympic semifinals at Wimbledon 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 who won the 2009 U.S. Open then sustained a serious wrist injury. "I definitely think he is right there again."
Federer later pulled out of his defense of the Paris Masters, which starts Monday, to rest and prepare for the ATP World Tour Finals in London the following week.
"It's the only right decision for me right now," the 31-year-old Federer said. "I had some niggling stuff and I didn't want to take a chance."
Del Potro ended a six-match losing streak against the top-ranked Swiss 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 final at Flushing Meadows.
The 24-year-old Argentine won for the second straight week after taking the Vienna title. His fourth title of the season is the 13th of his career.
Del Potro's victory came in 2 hours, 44 minutes compared to his 4-hour, 26-minute defeat at the London Olympics —the longest three-set match in history — when Federer won the decider 19-17 on Centre Court the All England Club.
