Aiden Markram has replaced David Miller for the final ODI as Sri Lanka bat first.
Despite the Proteas already winning the series, the final match has been made more interesting after Sri Lanka tasted victory in the previous encounter.
Proteas captain Faf du Plessis is already back home in South Africa, so his charges have to step up and show what they can do without his stabilising hand.
Markram comes back into the lineup to replace Miller while Kagiso Rabada has come back into the lineup to replace Lungi Ngidi.
Sri Lanka remained unchanged.
