What is liga mayor?

As an AI language model, I do not have information about a specific "Liga Mayor." However, "Liga Mayor" is the Spanish term for "major league." It is commonly used in reference to professional sports leagues, such as Major League Baseball (MLB) in the United States and Liga MX in Mexico. Major league sports typically feature the top-level athletes and teams in a given sport, often with higher levels of competition, media attention, and financial compensation compared to lower-level leagues.
