Interestingly, baseball didn't get to this point -- where so few balls are put in play -- by accident. It's a natural consequence of analytics ... because computers helped us realize that getting runners on base and moving them around the bases is actually a very inefficient way to score runs.
Build them like the Polo Grounds, old Yankee Stadium, and tiger Stadium, with nice, short, inviting foul lines and a deep centerfield. You have fences for the power hitters, good power alleys to produce lots of doubles (ane therfore men on base), and a place for pitchers where balls can go to die.
Ballparks like that make oyu play a mor einteresting brand of baseball.
