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.

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.

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.
