Unbeaten centuries by Tilak Varma and Sanju Samson have blitzed India to 283-1 total against South Africa and a massive Twenty20 win in Johannesburg.

Sanju Samson and Tilak Varma smashed scintillating centuries as India thumped South Africa by 135 runs in Johannesburg on Friday to claim the four-match Twenty20 International series 3-1 and inflict a heaviest ever defeat in the format on their hosts.

There's no secret to adapting to the conditions. Our plans were very clear as soon as we landed in Durban. Though we were up 2-1 in the series, today we wanted to follow the good habits and not worry about the result.
