What should i do?!! CRISIS(i would underline it but i cant!)!?

Right we ahve a rounders team at school, 10 or 9 people get picked to play. We have 2 teachers but they dont coach at the same time. at the practice most people come along. Not all the people who come along can play very well, so when it comes to picking of the team lets say coach A picks the team (All the good people and some alright players and then someone who cant catch throw or hit.) I never minded it. But when it came to the game the person who wasn't very good didnt do anything, just stood there we tried to throw her the ball but she didnt catch, when she came to hitting she didnt hit ect. Its not as if there wasnt anyone that didnt want to play. And Coach B took us for the game aganist another school, when the girl couldnt catch the ball and just stood there she asked her why she was picked to play, and said that there is plenty of other people that go to the club who can play and want to be in the team, so basically we lost the game, the girl was crying most of the team said some comments like you only needed to catch the ball or you could of at least tried. well the thing is she go tpicked again and some of the team dont like it becos we cant win a game wiht her on the team and we dont know what to do !! so we really need your help PLEASE ! x THank you X we thought that we could talk to Coach B or leave it talk to the girl or just leave it completey.
