I wish this generation of ball-parks would have been built with larger dimensions. It's a good example of the law of unintended consequences. There was a deliberate movement, heading into the 90's (when the current generation of ball parks started to pop up) to promote the HR. But what has happened is that lead-off hitters, and no. 2 hitters...and 7, 8, and 9 hitters...all physical/agility profiles can reach the fence and justify the launch, walk, or K approach. If a larger number of 'less strong' players couldn't reach the fence as readily, I think we'd see more players deploy a contact/put-the-ball-in-play approach. And of course, you'd have the natural outcome of more base hits falling in as outfielders have more territory behind them to cover. I do think there may be possibilities to 'soften' the ball (or at least reverse any trend to keep making more lively)...but the outcome would not be quite the same or impactful as it would be if the outfields were simply larger.
