The Cactus League is a spring training league for Major League Baseball (MLB) teams, primarily located in Arizona. It typically runs from late February to late March, allowing teams to prepare for the regular season. The league features 15 teams, including well-known franchises like the Chicago Cubs and Los Angeles Dodgers. During this time, fans can watch their favorite players in a more relaxed setting, often in smaller stadiums. The Cactus League provides an opportunity for teams to evaluate talent, develop players, and build team chemistry before the competitive season begins.
