Look, dumbass, I've not said anyone has. Perhaps you can quote that post.
Beyond that line of dumbassery:
You've agreed that a ball must exit the bat in excess of 90 MPH in order to travel 300+ ft.
You've agreed that it can exit the bat in excess of 90 MPH even if it's a groundball.
I've said "Do the math on a groundball that leaves the bat at 90+ MPH, bounces twice while traveling 65 ft and tell me how fast it is going."
You've said "I can't."
So WTF are you still arguing about?
