    New Zealand have been able to take wickets at crucial times. It has not looked the easiest pitch to start on so Kagiso Rabada needs to just try and get Marco Jansen back facing the bowler.

    What an innings from Marco Jansen. He has put his team in a position that they probably did not expect a short time ago.

    Corbin Bosch needs to try and get him on strike.

    Marco Jansen is beaten all ends up by a slower ball to finish the over, so he won't be on strike at the start of the 20th.

    A very nice piece of bowling, changing the angle and coming around the wicket. That is the last ball that Tristan Stubbs was expecting.

    New Zealand need to find quick ways to get back in the game now.

    Tristan Stubbs was looking to hammer that one. A wicket in time for New Zealand - they can get a new batter in.

    Stubbs b Ferguson 29 (SA 150-6)

    Swing and a miss from Tristan Stubbs, who departs for 29 (24).

    Lockie Ferguson pumps his arms and roars.

    Stubbs and Marco Jansen had put on 73 (48) for the sixth wicket, so it's a huge partnership broken.

    Marco Jansen brings up South Africa's 150 with a big six. Mark Chapman caught the ball but couldn't execute the relay catch with the covers and the advertising hoardings leaving him in a muddle.

    There's a four and a six apiece for Jansen and Tristan Stubbs in a very expensive over.

    22 from it.

    This is the over South Africa were waiting for. Jimmy Neesham tried to drag his length back and bluff the batter, but Tristan Stubbs is too clever for that.

    Tristan Stubbs is rumbling into gear.

    He dispatches a poorly executed yorker down the ground for four before nailing a sweep over square leg for six.

    Mark Chapman, on the boundary rope, chased across for a couple of paces before realising his efforts would be in vain.

    South Africa are slightly behind here but they have two set batters who are used to the pitch now.

    New Zealand bringing Jimmy Neesham back into the attack is the over South Africa need to capitalise on.

  17. SA 128-5published at 17 overs

    It could well be the turning point for South Africa, Dawid.

    Marco Jansen's six is followed a couple of balls later by a hard pull wide of mid-wicket from Tristan Stubbs for four.

    15 runs off the over. 160 is achievable.

    Marco Jansen knew exactly where that was going, straight away. He had a great swing of the bat.

    Brilliant shot - is that the momentum South Africa need?

    Well, that will certainly help South Africa's final hopes.

    Marco Jansen doesn't even look up as he fires Matt Henry over long-on for six.

    He and Tristan Stubbs exchange an energetic first bump.

    New Zealand are the past masters of the knock-out stages but it just needs a quick few runs and South Africa are right back in it. It can swing so quickly.
