Another rant

[Hillhouse]

The rise ball does "hop" once you reach a certain rotation and speed.

Here we go... buckle up

The neat part about being a pitcher is that you get to test your movement every time you go in a game. If your riseball isn't getting a bunch of swing and misses under the ball or foul balls over the backstop you are not getting enough back spin on the ball.

Doesn't really matter that a physicist will tell you that it's not physically possible to spin the ball fast enough to create enough Magnus Force to over come gravitational pull. If you can alter the arc sufficiently to create a path that is different than what the hitter's combined experience tells them it ought to be you have an effective riseball.

Not sure why we will accept the optical illusion effect in many other things but deny it when it comes to a riseball.

It kills me how many parents think their DD with a top speed of 48 mph can throw a rise ball.

I still can’t understand why people are denying that arise ball cannot “hop” to create rise. It’s the same theory as why an airplane can fly – see Daniel Bernoulli’s Theory on differing pressures. But having said that, do you need approximately four times as much spin as a drop to get the ball to rise.

I’m right there with you on that!

It is not that we don't believe it is physically possible for a ball to spin a fast enough. We don't believe that a person throwing underhand is physically capable of spinning the ball fast enough.

Northern, I hear this argument all the time. And I'm not arguing with you, I honestly don't know. Because for every "physicist" you produce that says it's impossible, I can provide ones that say it is. Factoring in, not every ball weighs the same, seam height, pitching into a wind, how strong the wind is, etc.

I realize the internet is littered with people who make outrageous claims about anything, only saying their cousin said he knew someone who saw this personally. So I get this is somewhat similar to that. But, I once did a clinic for a guy in St Louis who worked for the Dept of Defense. An actual "rocket scientist" from the DoD. And he told me that he could blow people's minds with this argument when he factors in the things above. Is he right? I don't know. I just know there's very smart people on both sides of this debate. And personally, I believe those who flat out refuse to believe it's even remotely possible have never seen someone who throws it correctly (backspin not bullet spin).

I agree with the other poster though who said, in a roundabout way, it's a lot easier to throw a drop. The hardest part of the drop is it's simplicity, even though many people make that harder than it needs to be too.

I don't know about smart, but I'll give $100 to anyone who can produce a side-shot video of any real pitcher in a game or practice with a riseball hopping.

Hopping as in a trajectory that looks anything remotely like this:

Bonus points if you can say why speed matters with a rise ball, more than say a drop ball

You’ll never see that. The hop on the ball will not be that pronounced. With enough spin imparted , It will hop a bit. Coupled with the trajectory. The factors involve are: force on the ball, weight, humidity, Temperature, speed, and rotation. Think about an airplane. where you have a pressure differentialFrom the top of the wing to the bottom of the wing. That causes lift. In the case of a softball that is pitched, it’s virtually the same thing. The speed of the ball and the backward rotation creates a high pressure above the ball and a low pressure below it. In short, Daniel Bernoulli’s theory.
