Good luck finding an 8u team or 8u tournaments. But that is where I would start. Go to the Ohio tournament section and look for tournaments within 2 hours of your location. Then look at the teams entered list.
At 8 if she is good enough to "travel" I would try to get her on a 10u team.
Better play and coaching all the way around. If you do not think she is ready for a 10u travel put her on a 10 recreational team. They will all use the 11" ball.
