K9 - not sure that an organization recognizing a guys worst pitch, which is getting crushed, should be thrown less is rocket science (hat tip to Houston, NASA and the cosmos). It seems like someone was doing their homework and said “Hey, maybe he shouldn’t throw this one?” Again, nothing to do with spin rate.
Fenway and Dominik85 - Agree spin rate = movement. My point is, in the short period of time a pitch is actually in flight, does it really matter? Extrapolating something that takes less than 1/2 a second to occur out to RPM, is it really relevant?

It does make a difference, quite a bit.

At 85 MPH (125 fps), increasing spin from 1200 RPM (20 rev per second) to 1800 RPM (30 rev per second) adds 5 inches of movement at 60 feet.
