Phillip Sinn came to the Red Bull Ice Hockey Academy from Mannheim at the age of 16 and celebrated his first title three years later with the U20 team in the then Erste Bank Young Stars League. Two more were to follow: One year later again in the U20 Young Stars League and in 2024 the Austrian championship title in the Alps Hockey League with the Red Bull Hockey Juniors.
In the 2022/23 season, the now 21-year-old made his debut in the DEL with EHC Red Bull Munich, playing two games. From the 2023/24 season onwards, the defender, who also played in two world championships with the German U20 national team, earned his place in the Salzburg professional team and won two titles in the win2day ICE Hockey League, including this year's championship. The agile defender with good offensive drive played a total of 94 games in the ICE Hockey League (3 goals, 15 assists).
