Five-year-old Hailey Dawson was born with a rare congenital disease called Poland Syndrome. This means she was born without a pectoral muscle and a functional right hand. Hailey doesn't let anything stop her, and it is her dream to play baseball one day. Her parents contacted researchers and engineers at the University of Nevada-Las Vegas for help. Their solution was brought to life using a 3-D printer to create the Flexihand which is customized for Hailey. Watch her throw the first pitch out to Manny Machado at Monday night's O's game. Go Hailey!
