Bhupathi had said earlier this year that Wimbledon was going to be his last tournament. However, he didn't play Wimbledon. I didn't think he had retired because he had earlier said that 2013 was going to be his last year on your, which he clearly didn't stick to. Neither he or his team have said anything about an official retirement, but Mirza recently acknowledged his retirement in a recent article, so I believe it is official.

Mahesh Bhupathi would rank as an all-time great doubles player but, sadly, his exit from the game has been unceremonious. His quiet slipping away from the sport that he played passionately at the highest level for more than two decades is so typical of the man, who was not a great believer in dramatising emotions. Despite being a brilliant achiever in a game that is his life, Mahesh was never much of a showman and was, perhaps, guilty of underplaying his own phenomenal successes. As an advantage court specialist with one of the greatest backhand returns in the game, he provided the perfect foil for the superhuman reflexes of Leander Paes at the net. They together will always be remembered as two of the greatest doubles players that India has ever produced.
As a mixed doubles specialist, few could match the skills and guile of Mahesh and I am proud to have won the Australian Open and the French Open with him as my partner, apart from the gold medal that we bagged for India at the Afro-Asian Games in 2003. We could have won more but while he was at his peak, I was still developing as a player and he seemed to have greater confidence in the more accomplished doubles specialists of that period. By the time I had matured, the advancing years had begun to take a toll on Mahesh's magic! Yet, together we were good enough to leave our mark as one of the most dangerous and respected mixed doubles teams in the world and itis unfortunate that bizarre circumstances prevented us from a shot at the Olympic medal in London in 2012.
