Keshav Maharaj is night watchman, hardly a batsman and occupying the crease. I would be surprise if he hang out much longer as new ball is just 5 overs away. Temba Bavuma is not impressive overall but if he and De-cock manage to form a partnership then they might have some chance, otherwise its Pakistan game.

Edit
And first ball of the day, Maharaj is gone...
Quinton de Kock is gone as well. With 4 wickets remaining, South Africa is having a lead of 50 runs. They need another 100 runs at least, in order to have the slightest chance of winning this match. The remaining batsmen (Rabada/Nortje/Ngidi) are all genuine tailenders. But then again, it is Pakistan on the other side and therefore nothing is guaranteed yet.
There was a time when the South African team had plenty of pace-bowling all rounders (Shaun Pollock, Jacques Kallis, Lance Klusener.etc).. but those days are long gone. They badly need such players.
