Does this regulation under the LL manual under 1.0 for Senior/Big League apply to softball? "The bat shall not weigh, numerically, more than three ounces less than the length of the bat (e.g., a 33-inch-long bat cannot weigh less than 30 ounces)." I just bought a Louisville Slugger Dynasty composite bat for my daughter and want to make sure it is legal for LL Senior softball. Thanks.
