One Protea's fielding change could have made a difference.

Williams took many singles running the ball to deep third man. Move the fielder to short third man and those singles disappear. And then the crucial last ball in Ngidi's last over. The pressure is on with 12 runs to get in the seven balls.....the third man is too square and a yet another shot is steered wide of the keeper and goes for 4. That settled it.
