No pitch, not even a riseball, moves above its initial trajectory.
DING, DING, DING!!!!
Wouldn't it be great if everyone understood THAT?

I didn't say that the Magnus force was greater in one case than another. In fact, I said the Magnus force was the same in each case (which is what you are saying). What is different is the time over which the Magnus force acts. It is longer for the 60 mph pitch than the 70 mph pitch, so the 60 mph pitch thrown into a 10 mph wind will break more than a 70 pitch with no wind. It is the ground speed that determines the flight timeSorry, but it still doesn't add up. Why does a ball launched at 60 mph into a 10 mph headwind produce more Magnus force than a ball than a ball thrown at 70 mph? The ball velocity through the air is the same for both. The only way I could see this working out is if the Magnus forces of both pitches are equal but the 70 mph pitch is traveling faster over the ground so the total amount of break is less from start to finish.
Now it's my turn to ask questions. I know what a "rise" is (a ball released with backspin); I know what a "drop" is (a ball released with topspin). How is a ball spinning that you simply classify as a "fastball". Is that the bulletspin pitch? In your experience, what does such a pitch do in terms of movement? What about a curve and a screw. Do those pitches have pure sidespin? What other pitches am I missing?

A fastball is not a pitch as it has no inherent spin characteristics. Rather it is by definition the fastest pitch thrown by the pitcher. It may be a rise, drop, screw, etc.
