Obstruction or nothing?

[heyblue]

The age group was 14&U. Fortunately, the games only lasted 55 minutes and there were no close plays at first. I wanted to use the obstruction rule, but wasn't sure I could because she never impeded or caused any of the runners to slow down. After speaking with my UIC, he suggested that if a girl even gave a hint of slowing down the least little bit, I could use the obstruction rule. I know I will see his team again soon and I will definitely make sure she changes the way she plays first base. Thanks for all the comments.
