DD complains of her hands hurting when she hits a ball in a certain manner. Mostly when contact is with the 2-3 inches of the barrel end. It doesn't matter what the temp is. So, it's an old, hand me down Muzuno that her sister gave her. Is the bat worn out? Would batting gloves make a big difference? She's 11 and now she's getting afraid to swing hard although I'm nipping that in the bud. I appreciate the help.
