The North American continent is the birthplace of several organized sports, such as basketball, charrería/rodeo, gridiron football, ice hockey, jaripeo/bull riding, lacrosse, ollamaliztl (ancient Mesoamerican sport), mixed martial arts (MMA), padel, pickleball, racquetball, ultimate ("ultimate frisbee"), and volleyball. The modern versions of baseball and softball, skateboarding, snowboarding, stock car racing, and surfing also developed in North America.
Sports leagues in North America use a mix of organizational structures. While common in other parts of the world, not all North American countries use the promotion-relegation (Pro-Rel) system for their association football/soccer leagues. Notably, Mexico's league has temporarily suspended its Pro-Rel system but is expected to being reinstated in the coming years. Leagues of other sports generally have a closed league using a franchise system.
