South Africa 271 for 9 (Rickelton 91, Stubbs 79, Adair 4-50, Young 3-45) beat Ireland 132 (Dockrell 21, Williams 4-32, Fortuin 2-28, Ngidi 2-35) by 139 runs
Career-best ODI scores from Ryan Rickelton and Tristan Stubbs respectively and career-best List A figures of 4-32 from Lizaad Williams helped South Africa crush Ireland by 139 runs to take a 1-0 lead in the three-match series.
Rickelton and Stubbs put on a 152-run partnership in the middle of two mini-collapses to help South Africa get to 271 before Williams' three-for in an eight-over opening spell left Ireland five down inside 14 overs. Ireland eventually only got to 132.
South Africa got off to a watchful start, with Rickelton doing a majority of the scoring early on. He cut Mark Adair through point for a boundary off the first ball of the match before hitting a couple of cover drives off Graham Hume and Adair.
In between, Hume induced the outside edge from him but was dropped by wicketkeeper Stephen Doheny.
But Adair got the breakthrough in the seventh over, when he changed tactics and banged one in short. Tony de Zorzi got a top edge as he looked to pull and was taken at deep backward square.
Temba Bavuma was then given out lbw first ball as a length ball jagged in from outside off, but was reprieved as he reviewed and ball-tracking showed the ball going over middle stump.
But it was short-lived relief for the South African captain, as Craig Young got another inducker to beat his defence and crash into the stumps.
Two wickets in two overs became three in three as Adair ended his first spell by getting Rassie van der Dussen to edge to second slip.
Once the first powerplay ended, spin came in and that led to more chances. Stubbs tried to reverse-sweep Andy Mcbrine but hit it straight to short third where Craig Young shelled a catch in the seventeenth over. One ball later, Rickelton lofted debutant legspinner Gavin Hoey down the ground and just cleared long-on, who was standing a few yards inside the ropes and had to track back.
Hume came back into the attack in the 22nd over, and was launched over long-on by Stubbs as he brought up a half-century stand with Rickelton.
Rickelton brought up his maiden ODI half-century off 74 balls in the 26th over and immediately put his foot down on the accelerator.
Hoey bowled a couple of half-volleys and Rickelton first lofted him down the ground before slog-sweeping him over midwicket. When Hoey shortened his length, Rickelton adjusted to steer it past the wicketkeeper for a boundary in what was an 18-run over.
Stubbs brought up a 62-run fifty in the next over, before Rickelton slapped Campher through backward point for another boundary to bring up the century stand. While the first fifty runs of their partnership took 73 balls, they took just 39 balls to get the next fifty.
Stubbs then came down the ground to Craig Young for a six over long-on that brought up 150 for South Africa in the 30th over, before Hoey was swept behind square by Rickelton next over.
Even as Stubbs hit McBrine and Adair for boundaries, that was the last one Rickelton hit. After facing ten balls without a boundary, Rickelton tried to go after a full and wide delivery from McBrine but ended up dragging the ball on, falling nine runs short of a maiden ODI century.
That dismissal sparked another mini-collapse as Adair combined with Balbirnie for two wickets in his next two overs. Stubbs pulled the fast bowler to Balbirnie at short midwicket before Phehlukwayo was done in by a slower ball and ended up spooning it short cover.
A slower ball brought about another wicket as Wiaan Mulder was early in his attempt to pull Young and holed out at deep midwicket.
Young then had his third when Williams skied his pull to deep midwicket, as South Africa lost five wickets for 38 runs.
Bjorn Fortuin took South Africa past 250 as he hit Young for two boundaries before pulling Hume to midwicket for a 34-ball 28. Ngidi then hit a four and a six to take South Africa to 271.
Ngidi continued giving South Africa momentum when the chase began, as he got Paul Stirling to chop on.
Balbirnie and Curtis Campher then rebuilt for Ireland, adding 35 runs including top-edged sixes from both batters, before Williams drew an inside edge from Balbirnie that hit the stumps.
Harry Tector brought out two gorgeous drives, one through point and one down the ground, off consecutive balls from Williams before he was trapped in front next ball.
Williams then got one to stop on Campher, who was early into a shot and ended up offering a simple catch to cover.
Debutant Ottneil Baartman then had his maiden ODI wicket when he got one to jag in and go through Doheny's defence. George Dockrell and Adair hung around before the latter got a feather edge off Ngidi in the 21st over.
Four overs later, Dockrell chopped on off Mulder before Fortuin trapped Hoey in front next over to ensure all of South Africa's bowlers got on the wickets column.
Williams returned to complete his quota and bounced McBrine out in his final over before Fortuin had Hume caught at mid-off to wrap up the win.
