Duminy took precautions to adjust to the gusts: "I spread my feet more in my stance to get a good centre base and my bat was wobbling in air when I lifted it so I had to take a firmer hold."
The force of the wind saw most fans seek shelter in the shadow of the RA Vance stand but a brave few bunkered down on the embankment. In a short-sleeved shirt, Martin Guptill was the most ambitious fielder but he also dropped the sole chance of the day at third slip from Petersen off Doug Bracewell when the opener was on 68.
The conditions certainly tested Daniel Vettori's famed patience in his 111th test, equalling Stephen Fleming's New Zealand record. "I've played about 460 days [of test cricket] all up and it'd rank somewhere near the bottom. It was incredibly tough and not easy for the bowlers. We wanted two wickets from our overs [and got none] so it was South Africa's day," Vettori said.
In a day of struggle for the hosts, a highlight was the wicketkeeping of Kruger van Wyk who has taken seven catches and conceded just five byes in 384.4 overs. His skills on both sides of the wicket have been welcome, as has his general vim in the field. If he bats well, it places further pressure on B-J Watling to regain his spot. Fine weather is forecast for the next three days.
