Frequently Asked Questions

What does “Drop Weight” mean in baseball?

Drop weight is the difference between the bat’s length (in inches) and its total weight (in ounces). For example, a 30-inch bat that weighs 20 ounces has a drop weight of -10 (30 – 20 = 10). The higher the negative number (-12 vs -3), the lighter the bat feels to swing.

When should my child transition from a -10 to a -8 or -5 bat?

Most competitive players transition to a -8 bat during their 11U or 12U season once their physical strength develops. By age 13 (13U), players should swing a -5 to prepare their muscle memory for the mandatory -3 BBCOR drop required in high school.

Is a balanced bat or an end-loaded bat better for youth players?

Over 85% of youth players perform significantly better with a balanced bat. Balanced bats have a lower Moment of Inertia (MOI), allowing hitters to accelerate through the hitting zone faster and maintain barrel control on off-speed pitches.
