Pro Player WM4

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

Maple. Dense and hard, the most common pro wood. Hits hard and holds up when the player squares the ball up; breaks rather than flakes when mis-hit. Quality varies a lot by maker.

Tip: Maple from a good maker is the best wood bat money can buy; maple from a cheap one is the worst.

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.

The middle of the range (about 2.45 to 2.55 in). Most pro turn models live here.

Tip: A safe default when you are not sure.

About 0.93 to 0.96 in. The usual choice: enough whip, enough strength.

Tip: Most players never need to think about this one.

A traditional round knob. The simplest feel and what most beginners should start with.

Extra weight toward the end of the barrel, so the bat swings heavier than its number. For some players it gives a better feel for where the barrel is; whether it suits yours depends on how consistently they deliver the barrel. End load is not barrel size: some skinny-barrel bats are end-loaded.

Tip: An end-loaded bat that feels heavy is the most common sizing mistake we see.
