U.S. junior leagues are organized sports leagues for young athletes, typically ranging from ages 16 to 20. These leagues provide a platform for players to develop their skills and gain exposure to higher levels of competition, including college and professional sports. The most notable junior leagues in the U.S. include the United States Hockey League (USHL) for ice hockey and various junior baseball leagues. These leagues often serve as a stepping stone for athletes aiming to secure scholarships or professional contracts. They emphasize player development, teamwork, and sportsmanship, while also allowing scouts and coaches to evaluate talent for future opportunities in collegiate athletics or professional teams.
