7. South Africa – 28:

15 South African players have contributed a total of 28 innings of double centuries for the Proteas. Their highest individual score in a Test match is 311* and they have scored 6579 runs in total over these 28 innings. They have produced some great players like Amla and De Villiers and so it is no surprise to see them in this list but maybe its a little surprising to see them at number 7.
