Jansen continues. Finn Allen launches a massive six to start the over and follows it up with a single. There's a loud appeal from de Kock and the South Africans for a catch behind, but the umpire isn't interested. Markram opts for a review. UltraEdge shows nothing -- an excellent decision as there's no contact. Seifert had swung hard across the line and missed. Seifert then turns the heat on -- smashing a towering six and backing it up with a crisp boundary. The pitch is looking even better for batting now. He finishes the over with a single.
18 runs come off it. After three overs, New Zealand are 37/0.
