DUBAI: Roger Federer confirmed Friday that he will team up with fellow Grand Slam winning star Martina Hingis for Switzerland in the mixed doubles at the 2016 Olympics in Rio. “Yes, I will play with Martina in the mixed,” 34-year-old Federer told sport360.com in Dubai. There had been widespread speculation that the two superstars would play together in Brazil. Hingis, 35, had reportedly made the offer to play with Federer and was waiting for a response from the winner of 17 Grand Slam titles. “I’m very excited about that because I haven’t played with Martina I guess in 15 years,” said Federer. Federer and Hingis last played mixed doubles together in the Hopman Cup in Australia in 2001, an event they won.
