South Africa won the toss and have opted to bat first against Sri Lanka in the only T20 encounter in Colombo on Tuesday.
Sri Lanka look to end off the tour on a high after falling to defeat in the ODI series.
While Sri Lanka won the largely one-sided Test series 2-0, the Proteas came back strongly in the five-match ODl series by taking an unassailable 3-0 lead.
However, the hosts came back strongly with wins in the last two encounters.
Teams:
Sri Lanka (Playing XI): Kusal Mendis, Kusal Perera, Dhananjaya de Silva, Angelo Mathews(c), Dinesh Chandimal(w), Thisara Perera, Dasun Shanaka, Akila Dananjaya, Lakshan Sandakan, Kasun Rajitha, Isuru Udana
South Africa (Playing XI): Quinton de Kock(w), Hashim Amla, Reeza Hendricks, Heinrich Klaasen, Jean-Paul Duminy(c), David Miller, Andile Phehlukwayo, Kagiso Rabada, Junior Dala, Lungi Ngidi, Tabraiz Shamsi
