In HS, son's games were called by his catcher (11th pick in 2015 draft and on Reds roster now), in college not so much and could shake or swipe off pitches. In Milb, he had this one catcher who only....or primarily called FBs, like all the time and son got frustrated and started shaking until another pitch got called. One time he after he had talked to the catcher prior to the game he said he shook about 6 times and finally got his pitch. Funny. That catcher has since been traded and no more of those issues.
