5 things which went wrong for South Africa in the 4th Test match

#3 A flawed batting line-up

Faf du Plessis should be batting higher up the order

With AB de Villiers' up to anyone's guess, it is imperative that the other South African batsman have to step up to fill the big man's shoes.

However, that has failed to materialise in this series and it is hard to ignore that the Proteas have themselves to blame by not sorting out the batting line-up properly.

In Faf du Plessis and Quinton de Kock, South Africa have their two most experienced batsman in the side but it is baffling to see the way they have been used throughout the series.

While De Kock came in at No 4 at the Kennington Oval, he was deployed at No 6 at Old Trafford. On both occasions, skipper Du Plessis batted at the No 5 spot.

As the cliche goes, the best batsmen have to bat at the top of the order and South Africa have simply not put this to practice. Du Plessis should ideally come in at No 3 or No 4 and De Kock should also be given the freedom to spend more time in the middle rather than batting him way down at No 6 or 7.
