I saw this in a scout's notes about a HS pitcher throwing 94, but getting squared up: ". . . he didn't seem to have much deception, but it's easier to learn deception and fastball movement that it is to learn to throw 94 mph."
My question is: is it easy to learn deception and fastball movement? Can anyone point to examples or pitchers who learned "deception"?
It seems to me that you'd likely have to change your mechanics, and who knows what the effects of doing that are.
P.S. -- I get his point about the difficulty of learning to throw 94. But I question the idea that it's relatively easy to learn deception and movement.
