What is the bat size rule for 13-15 yr olds?

For players aged 13-15 years old, the bat size rule typically allows for a maximum bat length of 34 inches and a maximum bat drop of -3. This means the bat's weight in ounces should be no more than 3 ounces less than its length in inches. For example, a 31-inch bat can weigh no less than 28 ounces. It's important to check specific league regulations, as rules may vary slightly.
