NASA and riseballs

[ice_67]

I'm not sure NASA factor this into their equation. I believe the "Jump Effect" of a riseball is caused by the centrifugal force of the earth spinning at 25,000 MPH. Also if your pitcher is facing into the spin you will get more of a jump. And everyone knows that in the summer months the riseball has more jump than winter months as the earth is closer to the sun thus the suns gravitational pull actually making the ball rise ever so slighly.

That's why we play mostly in the spring and schedule our games on new moon nights.

I don't know much about all the Engineer talk and such with the rise ball but I did stay at a Holiday Inn Express once! Any way I did play some catch with Bill Hillhouse at a clinic of his a couple of years ago and he threw me a couple of rise ball ( maybe only 50 mph) and the ball did move. He made me a believer!

My kid and I learned a long time ago that what a rise ball actually did - didnt matter. What a rise ball appeared to do - was the key.
