India triumphed over South Africa in the final T20I, securing a 3-1 series win. Arshdeep Singh's early wickets crippled South Africa's chase of 284, while centuries from Sanju Samson and Tilak Varma propelled India to their highest-ever T20I score overseas.

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.

After the explosive centuries from Sanju Samson and Tilak Varma and posing the highest team total (283) in South Africa, immaculate swing bowling helped India clinch the T20 series 3-1 at the Wanderers in Johannesburg on Friday.
