We were at my youngest DD's 8U tournament the last 2 days. My wife had pointed out one of the girls on a different team was able to send a ball to the fence at every at bat and she was barely swinging the bat. It was a CF7 by the way. My 11 yo plays on a A class 10u team and we have both DeMarinis and Xenos. She is the best batter on the team and hits for power. I have never seen her nor any other girls in tournaments we have played in have such an easy swing that sent a ball flying so far. After watching this girl bat (on the other team) my first thought was that her bat had either been rolled or shaved. (although I will admit I know very little about either) I then started wondering, how does someone question something like this? This was not a big tournament and I doubt they carry anything that allows them to test on the spot. What can be done if you suspect a bat might be illegal? Is there a way to tell without a compression test? Has anyone ever seen someone protest a bat during a tournament?
