Drop refers to the length of the bat minus the weight of the bat. The higher the drop, usually the lighter the bat is. Again, some leagues and/or programs have a limit on how much the drop can be so always check your rule book. If youâre a power hitter, you may do well with a slightly heavier bat. If you play small ball and try to get base hits, a smaller bat will give you more control. How to Buy a T-Ball Bat. What You Need to Know About Youth Baseball Bats.
