"Never give up on your dreams," Zion told WJZ last year. "It will come true."
Zion has shown so much progress that he was able to throw out the first pitch Tuesday at a Baltimore Orioles game, WJZ reported. Adam Jones caught the pitch on a small bounce as The Oriole Bird, mascot of the Orioles, cheered Zion on.
The trio posed for photos before the start of the game.
The Orioles went on to beat the Texas Rangers 5-1.
