PiecesOne-piece
Drop−10
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.

Barrel2 3/4
Lengths25, 26, 27, 28 in
KnobTapered
What this means

A cone-shaped transition from handle to knob, somewhere between standard and flared.

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.

Sizes25/15; 26/16; 27/17; 28/18
CertificationUSSSA (in product name)
What this means

The travel-ball stamp (1.15 BPF mark on the taper). Hotter than USA bats, barrels up to 2-3/4 in. Drop limits vary by state and age group.

Tip: Travel teams usually mean USSSA; ask the coach which state rules apply.

  • Tuned Mass Damper (TMD): Component within the handle absorbs vibration for an unbelievable feel with every swing – no matter where players make contact.
  • 2 ¾” Barrel Diameter.
  • Pro Design Knob Taper: Engineered to improve comfort, control and feel, this tapered construction at the base of the handle offers enhanced leverage through the swing.
