Ireland scored their only try in the first half through wing Mack Hansen as he found some rare space out wide and led 7-3 at the break but had to withstand a barrage of Springbok pressure in the second half amid a raucous atmosphere.
South Africa’s only try came from winger Cheslin Kolbe but they missed the conversion and three penalty chances to highlight their goal-kicking woes and perhaps hasten the return of experienced flyhalf Handre Pollard to the team.
Ireland will be odds-on to win the pool as they claimed a 16th test win in a row, while South Africa suffer defeat in a World Cup game for the first time in nine matches and will likely have to beat Tonga in their final group game on Oct.
