The PLAY BALL initiative is MLB collective effort to encourage young people and communities to engage in baseball- or softball-related activities, including formal leagues, special events and casual forms of play.  PLAY BALL events have become MLBs signature youth engagement activity during the professional and amateur baseball and softball calendar, especially on key dates throughout MLBs Championship Season and through the Postseason & World Series. PLAY BALL events demonstrate the positive way the game can serve as an outlet for physical activity, fun with friends and learning how to play the sport at its most basic levels.
