17-time Grand Slam champion Roger Federer has confirmed he will play mixed doubles with Martina Hingis for Switzerland at next year's Olympic Games in Brazil.
Speaking ahead of his appearance for the UAE Royals in the Dubai leg of the IPTL, Federer, who won an Olympic gold medal in doubles alongside Stanislas Wawrinka in Beijing in 2008 and claimed a silver medal in singles in London four years later, will partner the former Wimbledon champion, who came out of retirement in July 2013 to resume her career.
