Ireland have included uncapped allrounder Simi Singh in their squad for the triangular series involving Bangladesh and New Zealand.
He replaces offspinner Andy McBrine as the only change from the squad that was involved in the two one-day internationals against England.
Singh, 30, has been rewarded for impressive domestic and Ireland A form at the start of the season. He scored two half-centuries, including a 97, and took seven wickets for Ireland A on their recent tour of England and followed that with an unbeaten 70 for Leinster Lightning in the Inter-Provincial Limited-Over Cup.
"I've been impressed by his quality with both bat and ball," Ireland coach John Bracewell said. "He is an intelligent cricketer who can adapt to all situations depending on the match situation. He strikes the ball very cleanly, has good technique, and scores all round the wicket.
"His bowling is strong with subtle variations, mixing up his pace and he extracts good turn and bounce from the pitch."
Singh gained Ireland citizenship last month and spoke of the "honour" of being given the chance to represent the country.
"I'm absolutely delighted with my call up and looking forward to the matches," he said. "I came to Ireland as a teenager with a hope of wearing the green jersey one day and feel fortunate to have that honour now. I appreciate the support of my family and friends and also my club YMCA. This wonderful opportunity wouldn't have been possible without them.
"There's no doubt that I've been helped by strong performances for Leinster Lightning this past few seasons, and this campaign has started well with runs and wickets for Ireland Wolves. I'm so proud and grateful to get this opportunity - it'll be a great honour if I make my debut during this series."
Bracewell assured McBrine, who has played 22 ODIs, that he remained part of Ireland's plans for the future but felt he would benefit from domestic and Ireland A action.
"Andy is still very much in the selectors' minds, but we felt that it would be beneficial for him to play for the Wolves this week in the warm-up games against the Bangladesh and New Zealand XIs. He's a strong character and hopefully he'll respond positively with good displays this week."
