It was an extraordinary day yesterday. We thought it would nip and swing with the cloud conditions and then it did do that, and when we thought it would be perfect batting conditions with the sun out after tea, it seemed to do all sorts.

Although the stats suggest it didn't do that, the quality of the bowling was better than the quality of the batting.

I think you need to have a bit of practice in these conditions if you want to succeed.

Steve Smith and Beau Webster's half-centuries could prove to be match-winning if the bowlers continue to dominate this World Test Championship final .

They both had some luck early on but were rewarded for their positivity. South Africa, in contrast, were so defensive and Starc, Hazlewood and Cummins pounced.
