I have been trying to get the league to change rules to start pitching in 8u and take away coach pitch in 10u. They basically said I was crazy. Said that they games will last to long and at 10u it will be a walk fest and fielders will not get any action. So we send 10u pitchers that just started to 12u the next season and have a walk fest there.......I am trying but its hard when the main focus is baseball and softball is thought of being non-competitive until the 12 bracket. They wonder why all the talent in the area leave rec ball and goes to travel and would rather go to travel World Series instead of Regionals and on with the league.
I've coached 10U rec with and without the "no walk" rule, and full kid pitch at that age and class absolutely sucks. It is often a "walk fest" on at least one side, and NOBODY gets anything from that.
There are a couple of very nice features to kid pitch "no walk" at both 8U and 10U:
1. Giving a developing pitcher game time doesn't screw the rest of the team. Even if the pitcher can't throw strikes, a decent ball game for everyone can be had.
2. Absent getting hit by the kid pitcher, the hitter MUST put the ball into play to get on base. Unless the hitters are all terrible, the fielders will get a reasonable amount of action.
The downside is that you need a competent coach-pitcher, and it's more challenging than some might think. I suck at it, but fortunately, I had at least one assistant who could put it anywhere he wanted.
Yes, it is very possible that you'll have a "walk fest" at 12U, but the kids have had time to develop some skills and develop some attachment to the game. It is also easier to train a 12yo pitcher who is an otherwise solid player. If the rec league can't keep or develop 12U pitching talent, then the 12U rec league will die. However, if you discourage and bore kids as 8-10 year olds, you won't have ANY shot at maintaining a 12U division.
