Part of the issue is that you can't play baseball or softball at recess anymore, because they now take a dim view of kids bringing bats to school, or having minimally supervised use of school bats. What Baseball should be doing more of is marketing to parents the value of having their kids play baseball: 1) Kids of all body types are able to play - no need to have super endurance, massive size or height. 2) It's not a collision sport, kids can use their heads for thinking instead of contact with balls or other players, giving a much lower concussion rate: https://bjsm.bmj.com/content/50/5/292 (that report shows baseball has a lower concussion rate than even cheerleading) 3) Played in nice weather. No driving in snow to get to the game, no standing in pouring rain. 4) Encourages math skills. Batting average, on base percentage, slugging percentage ... it's all about the numbers. Follow that up with additional family marketing, like building a baseball-themed hotel / water park near Miller Park, with some package deals for rooms and game tickets, and fun off-season events.
