Day Four In Port Elizabeth.

In just over twelve minutes, yesterday morning, Stuart Broad and Sam Curran destroyed the tail of South Africa's first innings at the cost of a single run.
Stumps were flying in every direction and the follow on was enforced.
The home side were soon in trouble with a couple of wickets down and still some 270 runs behind.
Then the rains came down for four hours.
Part-time off-spinner, Joe Root, then showed that he can be at least as good as colleague Dom Bess when he grabbed a superb fourfer, in the short time available.
At one point, it looked as if England might have won the game yesterday but it was not to be.
Persistent rain is forecast for this morning as England strive to get onto the pitch to seize the last four wickets to take a series lead.
What a game of cricket! - I must learn to make fewer predictions because this awesome sport can wrong-foot you time and again.
Weather permitting, England should have this match sewn up.
Can the South African tail bat through and rescue a draw?
It seems unlikely but in this test series the impossible can happen and frequently has done so.
