Drop−3
What this means

Drop is length minus weight: a 30 in, 20 oz bat is a -10. A bigger drop number means a lighter bat for its length. Younger players use -10 to -13; USSSA 13U is usually capped at -5; high school and college are -3.

Tip: Check the drop your league allows before you look at anything else.

Lengths32, 33, 34 in
BalanceBalanced
What this means

Weight is spread evenly, so the bat feels lighter than its number. A player who uses the knob or handle to deliver the barrel often needs the weight balanced or down toward the hands. Balance is not barrel size: some big-barrel bats are balanced.

Tip: Which one is right depends on your player and how consistently they deliver the barrel.

Sizes32/29; 33/30; 34/31
CertificationBBCOR; NCAA; NFHS
What this means

Required for high school and college: drop -3, barrel up to 2-5/8 in. From the 2028 season high school will also allow USA -4, -5 and -6 bats; 2026 and 2027 stay BBCOR only.
