Lol. Why do you think I got her away from dad (me) and took her to a hitting coach. I played college baseball and many moons ago was a head HS baseball coach that played for the state championship. Even coached a few MLB. Dad wasn’t relating to daughter that acts just like him but a very different player. Never said a new bat would fix anything. Her current bat broke so we bought an Advanced for the first time. I just don’t really understand why you have to swing a longer bat when your 5.3.This is where every Dad goes wrong. They spend $$$ on bats instead of fixing the bat drag.
Fixing bat drag lasts a lifetime, and extends careers. A new bat will waste your money and your time, and shorten her career.
Having said that, pick a bat based on weight and balance, then get the longest one of those. Extra length mostly gives you plate coverage.
