re: How much difference will the flat seam baseball make?

Holy shite. Did I not say I would make it basic for you?

Do you want to know why the ball actually goes further with smaller seams? It's not as basic as drag moving forward through the air. It's because the ball can spin faster. The faster the backspin, the more pressure there is under the ball. It's the same effect on a curveball and the topspin pushing it down.

I had a thread last year when the change was announced explaining the physics behind the numbers. I compared the forces to english you see on a soccerball and sidespin.

And yes. There's a ball hit to the warning track at least once every two games by teams like LSU. Do you not watch baseball since you apparently quit your major league career?
