South Africa 269 (De Zorzi 104; Noman 6-112) & 183 (Dewald Brevis 54; Shaheen 4-33, Noman Ali 4-79)
Pakistan won by 93 runs
The national team brought an end to world champions South Africa's unbeaten run by sealing a 93-run victory in an thrilling and competitive first Test in the city of Lahore.
The Proteas, who had a 10-Test winning streak in Test cricket culminated in a win against Australia in the WTC final in June, were dismissed for 183 in pursuit of 277.
Starting the day on 51 for two, they lost century-maker De Zorzi lbw to pace bowler Afridi to the third ball of the day to shift the tightly balanced chase in Pakistan's favour.
Left-arm spinner Noman, who secured 10-191 in the match, dismissed Stubbs for two and clean bowled Dewald Brevis, who offered some resistance with a rapid 54.
Off-spinner Sajid also took advantage of significant spin to terminate opening batsman Rickelton's innings - he faced 145 balls for 45 runs - and Afridi came back in the afternoon session to knock over the tail with a impressive exhibition of reverse swing.
He trapped Verreynne leg before for 19 and bowled Prenelan Subrayen and Kagiso Rabada to secure the victory.
It was both sides' first match of the 2025-2027 World Test Championship cycle and moves the hosts straight into the number two spot behind table-toppers Australia.
Their victory was founded on key performances of ninety-three by opening batsman Imam-ul-Haq and, crucially, number seven Agha which lifted them to 378.
After that spinners Noman and Sajid Khan utilized favourable home conditions, as they had in their Test series win over the English team last year, to maintain their lead.
The next and last match starts on October 20.
