The common perception is that if you swing a lighter wood bat, that you will automatically increase your bat speed, thus increasing your chances to hit the ball harder.
However, the weight of a wood bat has very little to do with one’s ability to generate bat speed, and here’s why…..
A short compact swing with a downward angle (aka good swing mechanics / hands inside the ball), is the foundation to generate increased swing speed (bat speed).
A long looping swing (casting out / swinging around the ball) will translate to a slower swing.
Bad mechanics will equal a bad swing, and a slow bat.
A swing with proper mechanics will impact “bat speed” more so than a bat’s weight.
Therefore someone with proper swing mechanics should be able to generate the same swing speed with a 33″/32oz. wood bat, as a 33″/31oz. wood bat. And think of the weight we are talking about…..1 measly ounce. A stack of 10 pennies equals 1 ounce. Now think about how that ounce is distributed in the bat. Picture a stack of 10 pennies affixed to the barrel end of your wood bat. I can guarantee you that you would notice the slight increase in weight. However, you need to realize that that is not how that extra ounce will be distributed within the mass of the bat. Instead of visualizing a stack of 10 pennies on the very end of the bat, picture those 10 pennies lined up throughout the length of the wood bat. The extra ounce is evenly distributed throughout, thus making that extra ounce virtually undetectable.
Batters do not swing up, therefore they’re not fighting gravity. Hence, wood bats of the same length, with one an ounce heavier than the other, should not effect swing speed if batter executes proper swing mechanics.
Players, coaches, and parents are often misinformed about this. Just as many players think that by listening to the cup when banging their hand on a wood bat barrel will indicate if it’s a good piece of wood or not. The reality is that smaller knobbed wood bats will produce a sound with a higher pitch than wood bats with larger knobs. So yet another myth debunked.
