Hailey Dawson throws out a pitch 

Seven-year-old Hailey Dawson was born with a rare defect that left her without three fingers on her right hand. Once fitted with a 3D-printed hand, she has been dreaming of throwing out the first pitch at every Major League Baseball (MLB) stadium.

And her dreams are about to come true.

Following a video shared by Bleacher Report about the little girl on Twitter, more than half a dozen MLB teams stepped forward to let her throw out the first pitch at their ballpark.

Dawson is on a mission to spread awareness for Poland Syndrome, a rare disorder found in one of every 20,000 newborns that causes an underdeveloped chest wall on one side and occasionally affects fingers.

The second grader, who uses a specially designed 3D-printed hand created by researchers at the University of Nevada, Las Vegas, wants to show the world that kids with prosthetics can live normal lives and achieve their dreams.
