Swiss tennis star Roger Federer has beaten Jo-Wilfried Tsonga 6-3, 6-7, 6-3 in a nail-biting match to win a record sixth title at the World Tour Finals in London.
After a year that saw some uncharacteristic slip-ups from Federer in big matches, the Swiss former number one shrugged off a second-set comeback from the Frenchman to put his name on yet another page of the history books.
“I know it’s one of my greatest accomplishments,” Federer said about his latest record. “This definitely is an amazing finish again to the season. I’ve never finished so strong.”
