Wicket-batter Meso and spinner Naidu were part of the national U19 team that reached the final of the ICC U19 Women's World Cup earlier this year.

The young duo will be joined by uncapped all-rounder Miane Smit, who was a travelling reserve at last year's ICC Women's T20 World Cup while Nondumiso Shangase makes her return to the ODI squad for the first time since the tour to India in June last year.

Experienced all-rounder Marizanne Kapp will miss the upcoming series as she continues her conditioning block in preparation for the subsequent tours and the Women's World Cup in India.

Proteas Women head coach Mandla Mashimbyi said: "The mixture of youth and experience helps. It's an opportunity for these girls to show what they can do.

"Hopefully, whatever we've covered at the camp can be applied in Sri Lanka when we take the field. For me, it's not an opportunity for Karabo, Miane and Seshnie anymore.

"It's an opportunity for us to give them exposure at this level. Going forward and for the bigger picture, it's important that we expose them as much as possible to international cricket."This tour is an opportunity for us to check where the team is at. It's a work in progress. We want to get to a point where when we get to India in September, we are where we need to be as a team.

"But from a skill point of view, there's still a bit of work to do, and that's what we're busy with at the moment."

Proteas Women ODI squad: Laura Wolvaardt (Captain), Anneke Bosch, Tazmin Brits, Nadine de Klerk, Annerie Dercksen, Sinalo Jafta, Ayabonga Khaka, Masabata Klaas, Sune Luus, Karabo Meso, Nonkululeko Mlaba, Seshnie Naidu, Nondumiso Shangase, Miane Smit and Chloe Tryon
