Leander won the mixed doubles events at the Australian Open and Wimbledon with Martina Navratilova , both in 2003 . Weeks after the win at Wimbledon , Paes was admitted to the M. D.

While being treated , he had to miss the US Open , but he recovered by the end of that year . In the 2004 Athens Olympic Games , he paired up with Bhupathi , failing again at the semifinals stage . His next Grand Slam success was in the US Open doubles event in 2006 with Martin Damm . Paes led the Indian tennis team at the Doha Asian Games in 2006 and won two golds in the men 's doubles ( partnering Bhupathi ) and mixed doubles ( partnering Sania Mirza ) .
