What is your "trigger" for interference?

Concur. And when I will call INT depends on what level I am working. 10U, you're going to basically have to smack into the fielder to merit an interference call, and the same goes for obstruction. For a lot of the girls in my league it's a miracle they were paying attention to the base coach enough to start running - and this is true even in travel at times.

At an older level, if there's a sign of being impeded. Does the fielder, in your opinion, have a more difficult play to make because of an action taken (or not taken) by the runner? If yes, interference. If no, nothing.

By the way, does someone have the base awards for a situation like this handy? I am in France and don't have my FED book with me. Thanks in advance.
