Parent questions
Why does bat size matter so much for kids?
A bat that’s too long or heavy makes a young hitter late and teaches bad habits. A bat they can control lets them swing fast and learn the right moves.
Is a heavier bat better?
Almost never for kids. A lighter bat they can swing fast beats a heavy bat they drag through the zone.
Is it free and safe for my child?
Yes. It’s free, it runs in a phone or computer browser, there’s no sign-up and nothing is shared. Scores stay on your device.
