Saina Nehwal's preparation for the 2012 London Games received a shot in the arm today with the ace shuttler signing a contract with Olympic Gold Quest. The badminton sensation signed a three-year deal with the quest to join ace shooter Gagan Narang and four-time World Boxing Champion M C Mary Kom who also have contracts with the non-profit sports foundation. An elated Saina said she was looking forward to a fruitful relation, especially when former India hockey captain Viren Rasquinha is the COO of OGQ.
