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.
Deception’s difficult to discuss because there’s no definition of it in this context that would be accepted by the general population. Is it hiding the ball as long as possible so the batter gets his read late? Is it making one pitch type look like another, such as a CU looking like a FB. Is it making the delivery of the ball get all mixed up in the pitcher’s arms and legs? Is it making the pitch appear to come in at a different velocity than the delivery leads the batter to believe? Or, is it some combination of those things or something else entirely? If it can’t be defined, it can’t be measured.
Movement is something else entirely. Movement on a pitch comes because of gravity combined with the Magnus effect. Please see =====> http://www.texasleaguers.com/b...hy-pitches-move.html
Some pitchers’ deliveries make it easier for them to impart spin on certain pitches. FI, a 4 seam FB thrown right over the top isn’t gonna move very much, but the exact same pitch coming from a side-armed pitcher will often move a lot. A curve thrown over-the-top will curve from 12 to 6 and will take advantage of the max effect of gravity. But the same pitch thrown by a three-quarters pitcher will move horizontally as well as down, but won’t go down as much.
Any pitcher can learn how to impart spin, but whoever’s trying to teach them has to understand how much different “deliveries” affect the movement on the ball. Then too you have how much velocity affects movement. Assuming the spin rate is the same, the harder a pitch is thrown, the less time there is for the Magnus effect to work on it so it will move less, and if it’s thrown with less velocity it will move more. Those things cause control problems for the pitcher, so they’ll often throw with less velocity which has a different effect if it’s a FB than if it’s a curve.
It’s all veeeerrrrryyyyy complicated which is why pitchers never stop working on their craft.
