At 14 and whether your daughter is a pitcher or not, you should consider reading the drive mechanics thread in the pitching forum if for no other reason than learning exercises and workouts to prevent injury to her body while she is playing. There is a wealth of good stuff in there for girls and prevention of injuries. Then get her going on an exercise training program of some sort. Drive thread has some great ones of those also. Definitely recommend. There is a lot more athleticism required in the game than just throwing and catching the ball at higher levels.
