Duminy made 34 not out off 14 balls. <p></p> <p></p>Sri Lanka suffered another top-order collapse, going from 42 for no wicket to 79 for five and 96 for six before Udana s late aggression. <p></p> <p></p>Andile Phehlukwayo took four for 24. <p></p> <p></p>Hendricks was named man of the series after making a second successive half-century.
