This question has been going on for ages. My answer, yes it rises.
Well, if you dont believe it actually rises (if you throw it correctly), try linining up your nose 2 inches above your glove which is placed on a straight line trajectory of the ball and let us know the result. What a lot of physics discussions cant handle properly is the turbulence around the ball as it moves into the breeze.
This question has been going on for ages. My answer, yes it rises. I put a string about 10 feet in front of a pitcher. The string was 3 foot high. I put another string just in front of the catcher with a string over 4 foot high. The object was to pitch the ball under the first string and make it go over the higher string when it gets to the catcher. The pitcher I used is at UCLA now.

The bottom line here folks isn't whether it rises or not it's how effective of a pitch is it and where can your daughter learn to throw it properly. My daughters rise has hit good experienced catchers square in the mask because it went over their gloves and they missed it. It doesn't prove it rose or not. It proved that if it can fool an experienced, Gold level catcher it will likely fool a hitter. Works for me.
