Changing arm angles as a pitcher.

Is it a good idea for a pitcher to change his arm angle? It shouldn't be discouraged if the pitcher has the ability to throw strikes with the change.

Yet, I know for a fact that professional baseball and many baseball people feel that changing arm angles is taboo. Why? I guess they would prefer that the hitter have an opportunity to see the ball out of the pitcher's hand from the same spot every time.

Let's investigate this a little further. Hitters typically struggle when they face someone that throws from the same arm side as which they hit. Lefties struggle with lefties and righties with righties. I think it's safe to say that the numbers back this up.

So, why wouldn't you entertain the idea of a lefthanded pitcher dropping down occasionally and throwing to a lefty hitter? The same is true with right on right.

Now, it must be noted that changing arm angles or dropping side arm against an opposite handed batter is not necessarily a good idea. Why would you show the batter the ball even earlier? By dropping down you make the ball path take a an angle into the plate that is much easier to see and hit.

Bottom line- don't discourage a change of arm angles. But, understand when to throw it.
