The spin of Nathan Lyon and the reverse swing of Mitchell Starc sent South Africa crashing on the second day of the first Test against Australia at Kingsmead here yesterday. South Africa were bowled out for 162 shortly before the close, giving Australia a lead of 189 runs on the first innings. Lyon started the slide for the hosts and finished with three for 50 before the tall left-armer Starc gave a magnificent display of fast, reverse swing bowling to take 5-34.
