hi all - first time poster and neophyte baseball dad. my son is a pitcher and recently the sound of his pitched ball hitting the catchers glove has gone from a loud thud or whack to a crackle or the sound of a whip. its a noticeable difference. everybody has noticed. one of the kids on the teams grandpa (who used to play)said that is the sound of 86 MPH or higher. said that 86 is where the sound of the ball hitting the glove sounds different. none of us have a radar gun. I may break down and get one but this oldtimer says he can tell by the sound its at least 86. is approximating velocity by he sound of the ball hitting the glove an old wives tale or is there truth to it?
thanks everyone
It's pretty cool that your son is throwing hard enough that more people are taking notice. The sound of the loud thud of a pitch into a catcher's mitt is one of the beautiful things of the game. It's like you can almost smell it as well as hear it.
To answer your question, though, yes, wives tale. Velo can certainly have a bearing but as others have mentioned, newer/older gloves, where the ball is caught and one that hasn't been brought up... surroundings. There are some environments where the sound really carries or echos. If the wind is blowing the right way in one of our bullpens, a ball firmly hitting catcher's mitt has a piercing sound like something hitting metal... could never figure that out but think it has something to do with the adjacent chain link fencing.
In any case, good luck to your boy and continue enjoying the ride.
