Catcher, I totally agree with Coach May. If they develope and control a good fastball and then a changeup for strikes at that age they will do great. It was a great article in Sports Ills. last year about why all of a sudden arm injurys was rising for pitchers in MLB. SOme of them quite young. According to the research it was due to alot of breaking stuff being thrown at to early of an age and another BIG problem was not watching pitch counts for our youth pitchers. Coach May hit it on the head when he said they are not mature enough to really understand and also the strain it puts on there young arms and that very tender area called a growth plate in there elbow and shoulder. Just my opinion. I like Coach May did not let my son develope his curve ball until his freshman year (lastyear) in highschool. By changing speeds on the fastball and changeup he has been successful to this point!! Good luck and bring on some warm weather!! Play ball!
