After his great performances in the Hoofdklasse, Croon was called up for the national team to play in the 2016 Summer Olympics. At the 2017 EuroHockey Championship, where the Netherlands won the gold medal, Croon won the Under-21 Player of the Tournament award. He initially wasn't selected for the 2018 World Cup, but he replaced the injured Floris Wortelboer before the start of the tournament. He had to miss the 2019 EuroHockey Championship due to a shoulder injury he incurred during the 2019 FIH Pro League semi-finals.
