Custom Pro Birch I13 Heavy Duty

Softer than maple and more forgiving of mis-hits; hardens with use. A good choice for a first wood bat and for younger players.

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.

A big barrel (about 2.56 in and up) gives the most hitting surface. Its size does not decide the balance: some big-barrel bats are balanced.

A handle under about 0.93 in. It whips through the zone and feels fast, but it stings more on mis-hits and, in wood, breaks more easily. Common on pro models.

Tip: Thin handles and young hands do not mix well in cold weather; expect sting.

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

An ink dot on the handle shows the maker tested the grain slope. It is required for maple and birch bats used in pro ball and is a good sign of wood selection on any bat.
