The wicketkeeper-batsman will lead a 14-man squad over the competition in August and follows in the recent footsteps of team-mates Olly Stone and Alex Wakely.
Also included in the squad is 15-year-old Yorkshire pace bowler Matthew Fisher, who recently became the youngest player to feature in a competitive county match for more than a century when he played in a YB40 fixture against Gloucestershire.
The ECB’s national performance manager David Graveney, who chairs the England Under 19s selection panel, said: “Ben Duckett has considerable experience at this level after playing in last year’s ICC Under-19’s World Cup and captaining England Under-19s in the ODIs on their tour of South Africa earlier this year. He continues to develop as a player and has gained further valuable experience by playing for Northamptonshire’s first team this summer.
“This tri-series will enable our best young players to test themselves against opposition who are well versed in both playing and bowling spin, and will also provide important preparation for the squad ahead of next winter’s ICC Under 19 World Cup in the UAE.
“We welcome Matthew Fisher into the squad for the first time along with a number of other new players who have impressed in County second XI and first team cricket this summer. Matthew’s selection reflects both the selectors’ and Yorkshire’s view that he is ready to step up to the challenge of playing international age-group cricket.“
