The West Indies beat South Africa by eight wickets in the second Youth ODI on the island of Saint Vincent and the Grenadines.
SA U19 made five changes from the first Youth ODI, which they won by 18 runs.
After losing the toss and being made to bat first once again, the visitors were left reeling on 12-3 in the seventh over.
Despite brief reprieves from all-rounders Andile Simelane (14) and Michael Copeland (24), the youngsters couldn’t rescue the innings and SA U19 were eventually dismissed for 103.
Jayden Carmichael took 3-25 for the West Indies with McKenny Clarke (2-12), Johann Layne (2-14) and Anderson Mahase (2-34) bagging two apiece.
Defending a below-par score, the visitors made the ideal start when Aphiwe Mnyanda removed West Indies opener Shaqkere Parris for a duck.
But the hosts went on to make quick work of their chase, reaching their target within 23.2 overs.
Asakhe Tsaka picked up the other wicket for SA U19.
“The game didn’t go our way,” said head coach Shukri Conrad. “We again failed to adapt to the conditions in the first hour, which has proven to be critical. The nine o’clock start has proven to be really tough on the batters.
“We made five changes to our starting line-up from the first Youth ODI to give everybody an opportunity, which is really the aim of this tour; to ensure that everybody gets an opportunity before the World Cup.
“We needed to bat a lot better, it’s a tough wicket but not 100 all out tough, so we are going to need to come back stronger in Cumberland in two days’ time.
“Full marks to the West Indies. This sets up the series nicely now,” Conrad added.
The third encounter takes place on Thursday.
