6. Rohit Sharma (156 balls)

Rohit Sharma is one of the very finest batsmen India possesses at the moment. It is mainly because of the maturity he has been showing over the last 3-4 years despite having a lot of hiccups before that.
The star has come to the limelight when he was promoted as an opener from a middle-order batsman in 2012. He has scored his first double hundred against Australia in 156 balls as he holds the unique record of scoring two double hundreds in ODI cricket.
