They don't play year-round.
My teams play 4 to 6 fall tournaments. The biggest advantage to fall ball is to get swings against live pitching and to work on fundamentals. I treat fall as an exhibition season, so I put them in different spots and see how they handle them.
We take off the second half of July and August. Then we start practicing in September and play 4-6 tournaments through the end of October. We take off November and December, and then start our offseason program in January.
Tommy John stats are misleading. I'm not endangering a kid's arm because he plays 15-20 baseball games in the fall.
In this day and age, particularly in the part of the world we live, if your kid aspires to play baseball in high school, college, or beyond, this is what it's going to take to get him there, like it or not.
I disagree here. Playing baseball year round is not going to be the difference in your kid playing baseball in high school. Pure raw talent is what gets your kid on a team in high school. Once they get to Jr. High and into Sr. High is when the true craft of baseball is learned. This is the age when kids/young men are learning to use a man's body. Getting to college and beyond requires a higher level of commitment, sure. But until then, your kid can likely do just fine with pure talent.
You typically hear the phrase "A Five-tool guy".
Speed. Power. Hitting for average. Fielding. Arm Strength. Of those 5, only 2 can be developed and effectively worked on at a young age.
Hitting for average (contact) and Fielding. One could argue for
Power, which I can understand. However, at the end of the day, you can't truly teach power. Those that are capable can learn how to utilize their power, but one cannot consistently turn a contact guy(see Jake Mangum) into a power hitter.
Speed And Arm Strength. These two come with age and development. The old saying goes "You can't teach speed." That is true. Arm strength comes from proper conditioning of not only the arm, but entire body.
Add in a 6th tool of the
Mental Approach. None of the above 5 tools are worth anything if this is not up to par.
No amount of hardwork and and year 'round dedication to playing is going to give your young child any significant advantage into high school and beyond. Those that are going to throw 90+ will throw 90+ with or without that additional time as a youngster. Guys that will hit for power will hit for power when the time comes in their development to do so.
The theory of getting swings against live pitching is only effective if you do it continually. Taking 2 months off between seeing live pitching has the same effect as 4 months or more. Either way, you lose timing and have to re-adjust.
I am in favor of a child/young person putting in hard work and working on a craft at anytime. A commitment is what it takes. But the theory that one must be committed year 'round as you describe it above just to make a HS team is a bit of a reach.
