The magical riseball story.

[Ken B]

Ken, you seem like a bright fellow. But you say that the riseball is gaining elevation and then in the next sentence it is "dropping". Can't have it both ways. The ball will eventually start dropping but not between the pitcher and the catcher. In one with proper spin the ball will be rising the entire way through the zone and not flatten out or drop. That is a riseball. Forget about hops and changing planes and all of that.

Not sure about bright, but coming from you--I'll take it!

I don't do physics well, but from what I understand, a bullet shot straight into the air is dropping the moment force is removed (as soon as it leaves the barrell.) Same with a ball that has no other forces causing it to curve upward; as soon as it leaves the hand, it is dropping. Apologies if I have this mixed up.

The rate of climb is decreasing from the moment the ball leaves the pitchers hand. The ball rises through the zone because of the initial trajectory of the ball.

The ball begins to drop because of the force of gravity the moment it leaves the pitchers hand.

The spin on a good rise ball is such that it counters some of the pull (drop) caused by gravity such that the ball drops from it's initial trajectory at a slower rate than pitches with a non-rise ball spin.

I am a physics geek and I can say that Ken and Lou are right with 100% certainty.

rdbass,
Are you able to pull any of FFS's gif's of Escobedo from the Model Pitchers thread and post them here?

Thanks,
Ken

This whole argument is silly. A drop ball, fastball and rise ball are the same pitch.

Some just fall less than would be expected because of gravity.

I disagree. I don't believe a rise ball 'magically rises' but, sit on a bucket and tell me if gravity 'drops' the ball into your shins.
