Should I tell the coach off?

So my daughter is a pretty good softball player.  So good, in fact, she made the varisty team her freshman year.  She's been playing competitive ball since she was 10.  She's been told that if he keeps putting in the hard work, she could play at the college level. 

Last year, as a freshman when she was playing for varsity, we noticed the coach would make remarks about her being a "midget."  She's petite, 5'1" and 105 pounds, but what she lacks in size she more than makes up for in quickness and skill.  Personally, I don't think size should even be a factor in softball, but apparently it matters very much to this coach.  My daughter is a short-stop and plays second.  The coach didn't like her at second because when she covered first, she was "too small a target" for someone to throw at.  Stupid!  She didn't play short as a feshman because their was a senior there.  So he stuck on third.  She'd never played third, but she embraced and became an excellent third baseman.

Fast forward to now, she started the season playing third.  She has been near flawless on third.  Tagging out would-be steals on girls twice her size, fielding the ball like a pro, etc.  There was absolutely no reason to take her off third except the coach did and put a freshman there.  The reason he put this girl there is because her mother and father have spent an enormous amount of time sucking up to him.  He coached her older brother on the boys team for the last three years.  So they've been sucking up to him for a while.  We live in a small town where favortism is rampant.  It's all about who you know, what your last name is, or how much effort you're willing to put in to suck up to the right people.  Me?  I simply do not have it in my DNA to suck up.  I cannot do it!  The mere thought of it makes me so angry I think my head will explode!

So my daughter comes home from practice in tears last night because the coach was practicing the freshman at third and put her out in right field.  She said she asked him what had she done wrong.  He said nothing, he was just "trying to figure out the best 9-man combo for the team."  He said nothing was decided.  He was just trying things out.  So my daughter puts in the hard work.  She's well liked by her teammaters.  She is the ultimate team player while this girl and her parents trash talk the other girls on the team, saying things like "she can't pitch" or "she's so awful" or "I don't know why she even tries to play." So the message my daughter is getting is it doesn't matter what kind of team player you are, how much skill you have or how much work you're willing to do, you don't get what you want unless you suck up to the right people!

It is heart wrenching for me to see my little girl spirit crushed and that is what this coach has done.  I immediately wanted to call him or text him or whatever, but my daughter begged me not to.  I told my daughter she should boycott the next practice and when he asks where she was, give it to him.  She says "I can't.  I won't get to play in the next game."  My answer to her was that she's not going to get to play her position anyway, so why does it matter.  My daughter is a rule follower.  She does not ever buck authority.  I sat her down and told her that the people in charge are not always right and sometimes you have to stand for what is right and just and sometimes that means making the person in charge angry.  Am I wrong?

She went to youth group last night at church and came home and told me that she's not going to stress about it anymore.  God has a plan for her and she's going to leave it up to Him.  I guess I'm raising a better person than I am myself because today I'm still really upset about all this.  I guess I'll let her handle it, but man this is really a tough pill to swallow!
