Temba Bavuma attempts to drive his first ball from Mitchell Starc but doesn't get hold of it, the ball trickling back to the bowler.

A swing and a miss from the second.

Normal service resumes.

It was sunny at Lord's about 30 minutes ago but the skies have now turned a little grey, with the sun popping in and out. The Australia bowlers might fancy their chances this morning.

There's still a bit of cloud over Lord's but South Africa will be hoping the pitch starts to flatten out sooner rather than later.

Temba Bavuma resumes on three from 37 balls while David Bedingham has eight.

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.

Day two awaits at a sunny Lord's.
