South Africa are ruing a costly non-review after Australia's pace juggernaut hit back during a rollicking first day of the World Test Championship final at Lord's.
Kagsio Rabada (5-51) threw a mighty first punch, justifying Proteas captain Temba Bavuma's call to bowl first with his 17th five-wicket haul to help skittle Australia for 212.
But rank underdogs South Africa, aiming to break a 27-year title drought in ICC tournaments, were left reeling at 4-43 by stumps.
