K Rabada to Williamson, OUT! WILLIAMSON DEPARTS! That's a big, big wicket for the Proteas. The Kiwi juggernaut has been dismissed early as South Africa celebrate. A vital moment in the hosts' innings and they're in early trouble here. Rabada with a length delivery around off, it's swinging back in heavily as Williamson tries to meet it with a straight bat. Is beaten completely by the inswing as the ball goes past the inside edge and raps him on the back pad. South Africa go up in union and the umpire raises his finger. The kiwi skipper consults his partner and decides to review it. Since there is no Ball Tracking, the third umpire does not have any conclusive evidence to overturn the on-field umpire's call and so, the decision stays. New Zealand in some real trouble here.
