South Africa collapsed to 116-8 against Pakistan as fast bowler Mohammad Abbas ran riot on Day 4 of the first test as the tourists closed in on their first test win in South Africa in 18 years.

Fast bowlers Kagiso Rabada and Marco Jansen turned batting heroes on Sunday as South Africa edged Pakistan by two wickets to win a thrilling first test at Centurion and book themselves a place in next year's World Test Championship final.

Abbas, whose overall figures stood at 6-43 off 17 overs, produced a remarkable collapse. South Africa had seemed set for victory with only 50 runs required and six wickets in hand.
