On Saturday, the Los Angeles Dodgers and the Houston Astros will meet for Game 4 of the World Series. As with any Major League Baseball game, the competition will kick off with a ceremonial pitch. But this one will be especially awe-worthy, featuring a 7-year-old girl with a 3D-printed hand.
Hailey Dawson will fling the first baseball using a prosthetic hand that allows her to grip objects despite missing and underdeveloped fingers on her right side. When the invitation came in last month, “I started crying,” recalls Hailey’s mother Yong Dawson in an interview with CBS News. Hailey was born without a pectoral muscle on the right side, in a rare condition known as Poland syndrome. The resulting lack of blood flow to her arm meant that her right hand didn’t fully develop—she’s missing three fingers and has an underdeveloped thumb and pinky on her right hand. While she can do lots of things with her left hand, some things really take two.
