The 2023 World Junior Summer showcase ended on Aug. 4 and featured a small but balanced tournament-style competition between Finland, Sweden, and two United States squads split up into white and blue. The New Jersey Devils were well represented in the showcase, as defensemen Seamus Casey and Charlie Leddy played for the U.S., and 2023 second-round pick Lenni Hämeenaho played for Finland.
Of all the Devils’ prospects, Casey might be the most important in terms of growth and development. The 19-year-old defenseman played two games for both USA Blue and USA White and recorded one assist with the latter.
