I was rustling through stadium pics today and thought this forum the best and most recently educated in which to inquire. I noticed, for instance in nielson's recent PNC I think it was, the difference in basepath structures. Honestly, I've never given it much consideration until now. So, the questions:

Does the difference show up in any meaningful way in RL? Infield hits, defensive requirements, stolen bases, park factors, etc...?

What's the current composition of basepath coverings in the ML? Is it different at other levels? Are there rules or requirements by league?
