The San Francisco Giants added a special pitcher(投球手)for the day. It was small—yet fierce—Hailey Dawson, who has a 3D-printed hand.
The energetic 8-year-old from Nevada was invited to throw out the first pitch at the Giants game on Sunday. Dawson was born with Poland syndrome(综合症), a disorder in which affected individuals are born with missing or underdeveloped muscles on one side of the body. It affected her hand.
With a traditional prosthetic(假肢)potentially costing thousands of dollars, Hailey's mom, Yong Dawson turned to the University of Nevada, Las Vegas for help. She emailed UNLV engineering, and they accepted the challenge. Brendan O'Toole, chairman of the mechanical engineering department, said he and his team had got a lot of requests, "but this one was different." They got to work using a 3D-printer.Several prototypes(原型)and fittings later, Dawson got her first hand about four years ago.
Hailey's mother said the hand had given her daughter a wonderful lift. "When she puts this robotic hand on, it changes her personality and confidence level," Yong Dawson told CBS San Francisco. "I love seeing that. I just wanted her to have an even playing field."
When she arrived at AT&T Park on Sunday, Hailey got to hang out with players in the shelter at the side of the sports field. They even let her try on their World Series rings.
Using her 3D-printed hand, Dawson threw out the perfect first pitch. Then with a wave and a smile, she headed into the stands to cheer on her newfound friends on the Giants.
