Karl Berggren.

Karl Berggren is a midfielder for the New York Red Bulls, wearing the number 4 shirt in Major League Soccer. Specific details regarding his height, weight, nationality, college background, and birthdate are not publicly listed in available records, so his physical and biographical profile remains limited at this time.

As a central midfielder carrying the number 4 jersey, Berggren likely fills a defensive or box-to-box role, a common assignment for that squad number in the Red Bulls system, which has historically emphasized high-pressing, energetic midfield play. Current season statistics for the 2026 campaign are not available at this time, making it difficult to assess his output in areas such as appearances, assists, or tackles. For bettors, midfielders in this system can be relevant for prop markets tied to shots, key passes, and cards, particularly given the Red Bulls' aggressive defensive style. Once statistics become available, tracking his minutes and involvement in set-piece situations would provide stronger angles for props related to goal contributions or disciplinary markets. Monitoring official team and league sources for updated data is advisable before placing any wagers tied to Berggren's individual performance lines.
