Mignon du Preez hammered a brilliant unbeaten 116 to set up the Proteas women for a 68-run victory over the Irish in the second ODI in Dublin.
She was given excellent support by Chloe Tryon, who blazed her way to her third ODI fifty, putting on 89 in 13 overs for the sixth wicket. The Proteas women needed some steel at that point, for after a good start, fell from 140-1 to 168-5, with three of those wickets falling within four balls.
Tryon put her foot down, hitting five fours and a six among the 45 balls she faced before being caught and bowled to Kim Garth, daughter of Joburg-born Ireland bowler Jonathan.
Tryon has now piled up 145 in the two ODIs so far in Ireland, rising to the occasion in the absence of four senior players occupied with the Kia Super League T20 series in England.
With that support, Du Preez was able to power on past her second ODI hundred off 99 balls, with 13 fours as the Proteas went to 272-6.
Faced with such a daunting task, the Ireland women were never in the contest, collapsing to 86-6. The lower order showed a bit more grit, but it was a target too far. Against eight bowlers, the Irish were bundled out for 204 with 10 balls to spare.
The Proteas women are now two up in the four-match series.
