Knowing Clarke 1st thing in his mind would be to declare 1-11/2 hr(s) before the days close provided Aus bat that long obv. i.e Team first and this way he will also try to bat SA out of the game ..
Next thing in his mind would be the elusive quadruple and to achieve that his approach in reality would be..let us see Clarke still needs 176 runs...
1st & 2nd session : 70 runs each and in the 3rd with the declaration in mind he will try to score the remaining runs..Atleast that's what i want him to do
