So I did the nerd thing and made a list of players who would be the most likely to equal the Little Master's great knock. List is comprised of those who've made a Test double century AND who've made an international century off 75 or less balls (theorising that you get 150 balls in an ODI if you have half the strike, and 100 off 75 would get you 200 off 150).
Here's the list:
Sehwag (6 doubles, 5 fast 100s)
Gayle (3 doubles, 4 fast 100s)
Tendulkar (7 doubles, 1 fast 100)
De Villiers (2 doubles, 4 fast 100s)
Ponting (5 doubles, 1 fast 100)
Mo. Yousuf (4 doubles, 1 fast 100)
Pietersen (3 doubles, 1 fast 100)
McCullum (1 double, 1 fast 100 - no IPL 100s didn't count...)
Ryder (1 double, 1 fast 100)
Chanderpaul (1 double, 1 fast 100)
Yeah I was bored...
Sehwag and Gayle look the most likely candidates.
