This really is not a big deal. The rules of baseball are very similar from one level to another. There are just some idiosyncrasies that you have to understand and if you know how to umpire change the rules should not be a problem. Just read the rulebook of the level you are going to work. It is really not hard or hard to understand. HS rules are made for HS situations. OBR rules are made for pro ball and many of the rules are not translated to lower levels very well if you ask me. And obstruction is still an obstruction at any level. The thing you need to know is how to apply the rule to the appropriate level.

Baseball does not have all the rules differences as other sports and the rules differences are minimal at best. If other officials can come up with ways to figure out all the rules difference in other situations, I am sure you will manage.
