Billy Heywood, a twelve-year-old baseball fan, has just inherited the Minnesota Twins from his grandfather. As the new owner and manager, the first since the days of the Philadelphia Athletics, it's up to Billy to pull the team out of its slump, negotiate with some very large egos and somehow get the Twins into the playoffs. Despite the pressure, Billy executes the smartest strategy in the majors--he convinces his players to have fun, and in the process, Billy is forced to rediscover his youth as well.
