Here’s an interesting list from MLB.com about the various ground rules from every Major League ballpark. Here’s an example from Great American Ballpark:
Fair ball lodging in fence padding or chain link bullpen “windows”: Two Bases.
This gives me an opportunity to discuss something that I find interesting. When someone hits a ball that bounces into the stands, the announcer or scoreboard will invariably advise everyone that the batter hit a “ground-rule double.”
Well, no, that’s not true, actually. He hit a double, perhaps it could be called a “rule double,” but that situation certainly isn’t a ground-rule double. That’s because the situation is actually listed in the MLB rulebook as a double. It doesn’t have anything to do with the “ground rules.”
Just an issue of semantics, I guess, but it’s something a lot of people may not know.
