Unfortunately, around here, when the weather gets decent our kids actually play LESS. The high school football/basketball coaches all want the kids to come to their summer camps, making less time and energy available for the baseball player to work on his skills. However, I told a parent that if it was my kid and if his kid wanted to pursue baseball, I'd give up football and start concentrating on baseball specific workouts in the summer. However, apparently that was not an option....
My advise, if you think your kid needs more practice- set something up on your own. We did. I am not sure these high school coaches even get paid in the summer.
