This match has taken a very sharp turn.

South Africa is now four down – 4-216 – after Australia had an lbw call overturned on review.

The standing umpire ruled not out when young all-rounder Cooper Connolly and his teammates appealed for the wicket of Matthew Breetzke via lbw, but Australia went upstairs and technology delivered.

Replays showed the ball hit pad before bat. They also showed the ball would have gone on to hit off stump.

Breetzke is subsequently out for 2, and the Proteas are suddenly 4-216.

Oh, and that is Connolly’s maiden Test wicket. A terrific moment for the young man.

“That’s a moment he will never forget, at a moment when Australia needed it,” Simon Katich says in commentary.

“Pat Cummins gave him the opportunity and he hasn’t let the skipper down.”

That proved to be an outstanding bowling change by Pat Cummins. He brought on Connolly for a spell just before tea and the young gun delivered in his second over.
