Pro Select MC37 Semi Custom

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.

The handle widens into the knob like the bell of a trumpet. Players who choke up or want leverage like it; it also keeps the bottom hand from sliding off. Popular from high school up.

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.

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.
