What is needed to file a discrimination law suit on behalf of a child, that was denied an opportunity to play on a school team?

My daughter is 14 y.o.a, the only African American that tried out for the school 's sofball team a long with several teammates that went to the World Series and placed 2nd. They were selected and she was not. There were three separate tryouts, she was only able to attend one since she was also playing basketball for the school, the last tryouts was held on the day she had a basketball game, coaches was made aware but still posted the results. She was not selected, and I was told based on skills and ability. I presented newspaper articles showing she has amazing abilities and skills. I have been told by a lawyer there is no money recovery but I am having to spend $1k to get her on a travel team. Please, help. - Is this your question? Add additional information
