Ana knows that today will be perfect. She'll lead her baseball team to their first ever championship and then meet her new baby brother Louis. But when problems arise both on the field and in the hospital, Ana must figure out what perfect means to her. Can Grammie's science lesson somehow inspire Ana to lead the Rascals to victory?

With home runs and hugs and genetics and grapefruit, Ana teaches us the meaning of perfect.
