Very sorry to hear this. I'd have her focus on her form and continue building her power as she's able to control it. If you're not already playing her up, try to find the highest level club you can get her into.

Also, if she has good control and can hit her corners 3 out of 4 times, it's time to start on her junk pitches. Start with a change, then a curve (or slider,) screw ball and then the rise.

Unfortunately, if her catchers aren't able to track a fastball into the pocket, the breaking balls will be even tougher... What age is she in? I wouldn't worry too much about closing, unless she is closing early. I believe closing late will self-correct when she goes back to throwing in her comfort zone.

Best of luck with this...

Don't fix the symptoms, fix the problem. The issue is that the catchers are having issues with speed and force, teach them how to absorb the pitch and get them an inner catching glove with extra padding. I agree that throwing nothing but fast balls is a bad idea for your team and for your child... you'll burn her arm out.

if she likes dousent let her hurt you

Well ask her this
"is it them who is trying to make it big?
or is it her?
because she cant slow it down just beacuse she hurts her friends, her friends need to suck it up. it is softball, their are no wines, and complains.

That's tough for your daughter. Maybe you can help the catchers out by help them get quality gloves and add more padding if possible. It will be good practice for the catchers as well because as they get older they will face faster pitches. and remind them to use the pockets of the glove.

My daughter too pitches. In recreation league and in All Stars, the girls won't even throw with her. They ducked. My daughter is 10 years old and is a pitcher also. We went with travel ball and haven't had any problems with other girls ducking at all. She fits in better and is making friends with the travel team. I suggest you play her up or go to travel ball. Don't slow her down and don't let her slow down because she is better than the other players. It was easy for my daughter to move up because those other girls didn't throw with her anyways so she felt that they weren't her friends. Sometimes you have to just make new friends on another team and move up to get the better ball that your daughter is playing. My daughter called her other team, baby ball. Now, she is playing to her level and they are winning games. Do what makes your daughter happy. Do what is best for her in the long run. She isn't getting any better by playing with those girls that can't catch her.

Try putting a bucket upside down and placing a helmet, basketball or something that can withstand being hit numerous times on top of the bucket. The idea is to knock the object off of the bucket. Have her start a little short and back up farther away as she gets better. I helps tremendously with accuracy and strength at the same time..

not to make it sound so heartless but you have to tell her that when they step onto that softball field they are softball players. they have to work through the hard times for the better sake of the team

My daughter is a catcher and we have had the same problem with complaints of her "hurting hands". We played her up in rec ball but finally resulted to travel ball. A much better fit for a strong arm. I would suggest to your catchers' and their parents to get some catching lessons. They should be taught how to properly catch with a catchers glove, which apparently they are arent doing. I agree, not to sound heartless, but if you are afraid of the ball, you shouldnt be on a softball field. When your daughter is being held back by others, you are truly doing her an injustice. If all else fails, move her to another team where she can shine and grow. She will adjust quickly and enjoy the game much better.
