Kids are going through or about to go through tryouts for middle school and high school. Some kids in warmer areas may be past tryouts. I pulled these items from a list on another site. None of them have anything to do with baseball talent. But they all make a difference in making a team.
No a mediocre player is not going to beat out a stud for a roster spot with these things. But once e coaching staff gets past the top talent these things help coaches decide what players they want to work with. As a former coach the one that stands out to me is "body language screams."
Persistence is more important than talent
Respect the game as much as you want to be respected
Tuck in your shirt
Don't wear your hat backwards
Practice hard because you play the way you practice
It doesn't take any talent to hustle
Agree to let your coaches train you
Don't tell people what you are worth, prove it to them
Your parents love you, but they don't know more than your coach about baseball
Don't let anyone make an excuse for you
Maintain eye contact with all adults when they talk to you.
It is your coach's opinion of you that counts. He makes out the lineup. Fail to understand this point and you will soon be out of the game.
Life is not fair. Regardless of what some people want you to think.
Body language screams. It never whispers
You don't have to be a great athlete to be a good baseball player
When you jog to warm up finish first.
When you stretch do it best.
When you play catch, throw to a target and hit it every time.
When you play catch, catch the ball or block the bad throw and keep it in front of you every time.
When you are doing a drill, do it perfect, every time.
Go hard all the time. Never walk on a baseball practice field.
Baseball reveals character it doesn't build it.
Character means doing the right thing when nobody's watching
