Sri Lanka have included teenage fast bowler Lahiru Kumara in their squad for Sunday's third one-day international against Australia.
Allrounder Milinda Siriwardana, who was part of the squad for the first two games, was omitted in the only change announced on Friday to the 16-man squad.
Kumara was part of Sri Lanka's successful under-19 tour to England, where the youth Test and ODI series were won recently.
His teammate, batsman Avishka Fernando, was already in the senior squad as Sri Lanka looks to build a team for the 2019 Cricket World Cup.
Kumara, who has no first-class experience, took 19 wickets in both formats during the England tour.
