Could someone please describe the "experimental rule"? Just got the new Fed Rules package in the mail today (here in Oregon, it is raining with ice pellets, most of us won't see a field until sometime in April), and don't see anything about it, probably because Oregon isn't using it. Admitedly, I haven't had time to read all 3 books cover to cover yet, but I don't think it is in the Rules, Case Book, or Umpires Manual. I have seen a press release, but it didn't include the actual rule. Even if we aren't using it here this year, it would be nice to know what it says. Thanks in advance.
