Kagiso Rabada claimed a six-wicket haul today as South Africa bowled Sri Lanka out for 224 in their second innings to win the second test by 282 runs with a day and a half to spare. The hosts have thus taken an unassailable 2-0 lead in the three-match series. Sri Lanka failed to last the first session of the fourth day at Newlands, having resumed on 130-4 and being dismissed after just over 100 minutes of play. They added 94 runs for their final six wickets to fold easily after being set a huge 507-run target yesterday.The 21-year-old Rabada, who finished with figures of 6-55 and a second 10-wicket haul in a test, ran through the visiting batsmen in a fiery seven-over spell. South Africa won the first test in Port Elizabeth by 206 runs and will be seeking a whitewash of the series in the third test at the Wanderers in Johannesburg from January 12-16.
