The 19 Most Unhittable Pitchers? according to Bing

I have heard of him. Your descriptive in your post gives pretty much everything I had heard about him though.

 

I read somewhere that Dalkowski was "double jointed" and that help with his velocity.

Well I am double jointed in my fingers and can bend my wrist and elbow well beyond the normal range. I couldn't play basketball on asphalt because my knees were "loose" and took a pounding. I probably had very loose joints everywhere and maybe that is why I could throw pretty hard. I probably had a few more degrees of motion adding up the velocity of the pitch.

Funny thing is that I never dislocated anything.
