Throwing Like A Girl by Mackey, Weezie.
When Ella suddenly transfers from her Chicago hometown to Dallas, Texas, she feels alien in her new private school. With her clunky Midwestern clothes she feels like she doesn't even compare to the girls in flowing skirts that go to Spring Valley Day School. And without her friends to help guide her she feels so lost. But then on an impulse she decides to try out for the softball team, and she makes it!
