Babe Ruth rules

[bigwes68]

I hate to do this, but I need a little help. My hometown is hosting the 14U Babe Ruth state tournament this weekend...to my knowledge, they have never hosted a fastpitch tournament of any kind. They have asked me to umpire the tournament because I'm in town for a couple of weeks and there are no other experienced softball umpires in the area. I've never done any softball below the high school level and, therefore, have only called NFHS and NCAA rules. The tournament starts Thursday, I found out about it tonight, and I don't have a Babe Ruth rule book. Can anyone give me a quick rundown of the major rules differences from Fed and NCAA, or at least point me toward a resource where this info can be found quickly? Thanks in advance.
