Obstruction? F5 plants foot on inside corner of bag, won't move for a runner

[Gee]

If he impedes the runner you have obstruction. If he doesn't you have nothing. A catcher will always set up with his foot on the corner BEFORE their is a play. However he will get it out of their as soon as he finds there is no play. You are right about telling the manager about the safety factor, if for no other reason than to cover yourself in case of an injury. After doing that, all you can do is make the call.
