Shivam Dube continues. Donovan Ferreira nudges one to midwicket for a single. Markram drives to long-off, but Arshdeep Singh puts it down -- India's second dropped catch of the night. A reminder that chances against Ferreira are costly, given how dangerous he can be. Markram then works one to long-on for another run. Ferreira responds by slamming a boundary and follows it up with a single. Nine runs come from the over, taking South Africa to 67 for 5 after 13 overs.
Varun Chakravarthy returns -- and strikes immediately. Ferreira cuts one to long-on for a single. Markram is then struck on the pad, with a leg bye added. Next ball -- bowled! The mystery spinner knocks over Ferreira, removing the danger man.
Varun claims his 50th T20I wicket as Ferreira departs for 20 off 15 balls.
Marco Jansen is the new batter.
