New Zealand might be playing with a "refreshing" energy, but South Africa look primed to do real damage as the World Cup approaches its pointy end.
It's an unashamedly biased opinion, coming as it does from South African legend Shaun Pollock, but should not be discounted.
"They are creating some good momentum," he said of the team he represented from 1995 to 2008. "Five of the top six batsmen have scored centuries and the bowlers are finding form."
The first point is pivotal. Whereas New Zealand might be the form team of the competition to date, their success on the bowling front has almost hindered the batting.
Of their top six, only Brendon McCullum and Kane Williamson, maybe to a lesser extent Corey Anderson, can claim to be in any sort of form.
