Boy who received double hand transplant throws first pitch at Camden Yards

BALTIMORE -- The first child in the world to undergo a double hand transplant threw out the ceremonial first pitch at the Baltimore Orioles - Texas Rangers game Tuesday night.

Nine-year-old Zion Harvey tossed the baseball to Orioles centerfielder Adam Jones before the game started.

When he was 2 years old, Zion developed an infection that required his hands and feet to be amputated.

He became the youngest patient to receive a double hand transplant when he had the procedure done at the Children's Hospital of Philadelphia last July.

Since then, Zion has been taking part in rigorous therapy sessions in order to regain hand function, including the ability to throw a baseball.

He impressed everyone at Camden Yards with his pitch. Way to go, Zion!
