Five-year-old Orioles fan throws first pitch with prosthetic hand
Monday August 17th, 2015

Five-year-old Hailey Dawson was born with a rare disorder that left her right hand underdeveloped, but that didn’t stop her from throwing out the first pitch at Monday’s Baltimore Orioles game. 

Hailey has Poland Syndrome, which affects the pectoral muscle in the chest and the fingers on one hand. Thanks to the engineering department at UNLV, though, she is able grip objects with a 3D-printed robotic prosthesis.

Wow. What an amazing experience for Hailey and Zach. @masnorioles @baltimoreorioles #baseball #haileyshand #orioles

Hailey lives in Las Vegas but her father is from Maryland and their family roots for the Orioles, so Hailey’s hand has the team logo on the back. Before throwing out the first pitch, she got Manny Machado, her favorite player, to sign it.

The design files for Hailey’s hand are available for free online, allowing anyone with a 3D printer to build a similar device at low cost.
