I coached a 9U AAA team that is likely moving to majors this upcoming year at 10U. We typically have 11 or 12 kids, every kid sits once before anyone sits twice. No kid has a set position on our team because how can you tell a 9 year old is a 2B only at this point? Each kid has at least two infield positions, plus outfield and then 4 or 5 can catch. Each kid pitched at least a handful of innings and the ones that pitched less often are pitching more in fall to develop their skills and looking good.When I was a younger man I coached little league baseball, I made a deal with every kid on the team, You make it to practice you will play, I obviously started the better kids but every kid got at least 2 innings in the field and at least one at bat. It pissed off some of the parents of the “better” players at first but I must say almost all of them came around to understand that I was trying to make it fun for all the kids and not just their kids.
I will say it’s a totally different world now and I doubt I would have the same success.
Our group doesn’t have tryouts or any of that stuff but they’ve obviously been successful. They may not have superior talent, but they play better as a team than most others because they know they can trust their teammates, they know they will get their chances, etc. We have created an environment of having fun and playing ball while keeping them competitive.
This is a long winded way of saying that at younger ages you can do it the right way while also winning, developing the kids and building their interest in the sport.
