A common throwing problem — dipping the front shoulder
Maybe I’m just more acutely aware of it now because I’ve been working with a couple of players on this problem. But more and more I’m seeing an oddity in the throwing motion of some female softball players: they dip their front shoulders to initiate the throw.
They start out ok, i.e. they turn their bodies and take the ball back properly. But when it’s time to start moving forward, their first movement is to lower the glove-side shoulder instead of leaving it in place and driving the throwing shoulder through. When that happens, they tend to look like they’re throwing a hand grenade in a WWII movie instead of a softball. The back shoulder gets stuck right about the time they get to square, and the throw is mostly arm.
They may get the ball there, but it’s not very efficient. And it won’t be as hard as they can throw. If you see this, you need to get the player to keep her glove side shoulder to stay in place, then drive the throwing side shoulder through. I refer to it as replacing the front shoulder with the back one. When they’re finished, the throwing shoulder should be lower than the glove side. At minimum, they should be the same height.
Don’t be fooled by looking at videos of MLB pitchers, either. They are throwing off a high mound, and what looks like the front shoulder dropping down is really the whole body going down because of the hill. If they were on flat ground the glove shoulder would remain in place. That’s the way field players throw.
If your player can’t get the hang of leaving the shoulder up, trying having her raise her glove straight up over her head, and leave it there while she throws. You will see an immediate improvement. Then slowly have her lower it until she can make the proper movement with a full throwing motion.
It takes some time and practice to overcome this habit. But in the end it’s worth it.
