For example, maple was once a rarely used wood type for baseball bats, now it is considered the most popular choice for professionals and amateurs alike. The reason for such changes has a lot to do with wood science and how the bats are manufactured. Northern White Ash harvested in northern Pennsylvania and New York has been the staple wood for bat production for over 100 years. The primary reason
is because it is light and strong. It is also what is called a ring porous species, which essentially means the grain is very visible and distinct. This property does have a down side. Because of the spacing in the annual rings, Ash has a tendency to separate or what is commonly referred to as Flaking. Flaking is even more pronounced if the hitter makes consistent contact on the face grain of the wood. The problem with that is the face grain is actually the stronger side to make contact on. The result is a bat that performs well but does not last as long. Maple does not have this problem. Because it is considered a diffuse porous species the grain is much shorter and tighter. That also results in a harder stiffer bat. Many players believe these properties lead to greater performance. The reason Maple was not used in bats until recently has to do with the drying process. All bat woods must undergo a drying process after they are cut or split from logs to get them to appropriate moisture levels for maximum strength and weight ratios. Ash was always kiln dried but Maple must be vacuum dried otherwise it will be too heavy to use. Also Maple is more susceptible to tangential or face grain breaking. To correct this problem Major League Baseball implemented the ink dot test and guidelines for acceptable slope of the grain allowances. In English that means they found a way to eliminate wood that was not straight and thus cut down on the wood bat breakages. Partly because Ash is dying out, Birch has become an increasingly popular choice for wood bats. It maintains the flexibility of Ash but incorporates the hardness of Maple to form a sort of “hybrid” that many players are starting to appreciate. The only down side to Birch is that it’s strength does not correlate as well to the slope of the grain as Maple. The result is a wood that is very hard to predict. Whichever wood you choose from us, you can bet it will be the highest quality available!
