2. Nathan McCullum (New Zealand) – 355.55:

Nathan McCullum has always been overshadowed by the brilliance of his younger brother Brendon McCullum in international cricket, yet he had his moments of glory. In 2013 Hambantota ODI against Sri Lanka, Nathan played a blinder of an innings which stunned the hosts. In only 9 balls he smashed 32 runs at a jaw-dropping strike-rate of 355.55. Out of 9 balls, 6 balls went for a boundary.
