Mitchell Starc edges behind but again, the ball lands just in front of Aiden Markram at slip.

Lungi Ngidi has got the ball on a string.

  • Thoroughly enjoyable, thanks. Nowhere I'd rather be!

    How's your dull afternoon watching Smith and Labuschagne bat going Ffion?

    Just a single off Mulder's latest as South Africa continue to squeeze.

    Here's how Lungi Ngidi got rid of Beau Webster.

    Well, I've got tickets for the first couple of days, so let's hope not.

    Alex Carey edges, the ball falling just short of slip...

    As much as I love seeing Australia fall apart, you just know they'll be 450-3 in the first Test at Perth stadium come November.

    Stunning turnaround from Lungi Ngidi, who had a tough day yesterday. He now has three wickets and Australia have lost 5-29.

    This game is well and truly alive. Australia are falling, crumbling, stumbling.

    WICKET

    Cummins b Ngidi 6 (Aus 73-7)

    'Bowled him!' - Ngidi yorker takes out Cummins for six

    Or not...

    Pat Cummins is cleaned up, a fuller delivery from Lungi Ngidi which ricochets off the pads and into the stumps.

    I can't quite believe what I'm seeing here.

  • Jim Maxwell
    BBC Test Match Special commentator at Lord's

    The Australia captain is counter-attacking here. These could be vital runs in the final analysis.

    I don't think South Africa will be wanting them to even get another 20 here.

  • Aus 71-6

    Pat Cummins may have other ideas.

    He's already taken six wickets today, and starts his innings with a lovely flowing cover drive for four.

    This has been a great comeback from Lungi Ngidi from the way he was playing yesterday.

  • Jim Maxwell
    BBC Test Match Special commentator at Lord's

    The game is going away from Australia at the moment.

    Lungi Ngidi has found his stride in the last half an hour.

  • Not out

    Yep, going over the top of the stumps.

    On we go.

  • SA review

    Could be seven...

    Alex Carey skips down the pitch and is struck on the pad by Lungi Ngidi. I suspect he's too far down, but South Africa are on top and sense another opportunity.

    Australia 66-6....has Christmas come early?

    B Kelly, Balham

  • Aus 66-6

    We're not quite in two-day Test territory but this is chaos.

    Australia lead by 140 as Mulder rips another between Pat Cummins' bat and pad.

  • Jim Maxwell

    That clattered onto the off stump. Who can score some runs?

    Australia are in the mire.

    WICKET

    Head b Mulder (Aus 66-6)

    'He's ripped through his defence!' - Mulder bowls Head for nine

    What is going on?!

    Travis Head is done by a beauty from Wiaan Mulder, the ball pitching on off stump before nipping back in sharply through his defence.

    The quality of bowling on display over the past two days has been sensational.

  • Jim Maxwell
    BBC Test Match Special commentator at Lord's

    Beau Webster doesn't launch an innings this time. The game is moving fast. 14 wickets yesterday and 11 today.
