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 5/8
Lengths29, 30, 31 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.

Sizes29/19; 30/20; 31/21
CertificationUSA Baseball
What this means

Required in Little League Majors and below, Cal Ripken, PONY, Dixie and most rec leagues for players 14 and under. Barrel up to 2-5/8 in, no drop limit.

Tip: If your league says USA bat, a USSSA bat will be turned away at the plate.

Maker SKUWBD2568
The maker says
  • Anomaly Connection: Pairs the barrel with a stiff, composite handle to offer feedback while maximizing comfort, bat speed and energy transfer on contact.
  • Anomaly End Cap: Designed to work with composite barrels, using light and durable materials to reduce swing weights, improve bat control and optimize performance.
  • Two-Piece Composite Construction: Designed for improved weight distribution that allows for great balance, bat speed and barrel control.
  • Dark Matter Composite Barrel: A groundbreaking composite material and construction resulting in a new barrel shape with a more gradual taper that increases performance throughout the barrel, translating to a higher performing, better feeling sweet spot.
  • 2 5/8" Barrel: The largest barrel diameter permitted delivers improved performance with a larger sweet spot.
