Son is a freshman LHP. He will be 15 this March and is 6’ 2" tall and a 170lbs. So he is a good sized athletic kid, lanky but not skinny.
He is taking pitching lessons for the first time (He has been pitching for several years…basically all fastballs). He has learned to throw a slider (picked it up easily) a cutter and a split finger change up. His instructor is also a LHP so they have a great connection and he has really helped son tweak his mechanics to improve his control so that is why I think he picked up the new pitches rather quickly.
I am very comfortable with him throwing the slider as he has learned to throw it properly and doesn’t throw many in a session. His instructor and I have both cautioned him in “falling in love” with it and throwing it too often even when he is having success with it. Saving it as a strike out pitch when needed. He has an excellent hard 2 seamer with a lot of movement so he uses that a majority of the time.
I guess my question to you all is how often is too often in the course of a game 5…10…20…30 ??? Also is it as effective against a RHH as I would think it would be against a LHH? I’d think he’d throw the cutter more often to a righty and the slider to a lefty.
Any thoughts are appreciated.
