Virender goes Viral !!

Once in a cricket match between India and Australia, the Indian scoring machine Virender Sehwag went to bat first. It was October 20 that day, the day when this wonderful cricketer was born and the day when god gave him the power to make shots as per his will.

Provided that he faced the first ball of the innings and didn't get out. What is the maximum amount of runs he alone could have had scored??

Directions:

1) He can even hit six sixes in an over.

2) Strike changes after every over and the batsman on the other hand will give strike back to Viru as soon as possible.

3) There were no "no balls" or sort of any extra runs given in that match.
