The eight-year-old doesn't remember much about what happened during his first Cubs game when he was hit by a foul ball of the bat of Cubs pitcher Ted Lilly. The boy's injury was so serious, his parents were not sure if he would survive.
But Saturday, the Cubs and his parents surprised him with a return trip to Wrigley.
It turns out Dominic has quite an arm.
"I was surprised. I went up because I didn't know. He's only 8 years old. I know it's his birthday and he's feeling good, but I didn't think he was going to be able to make it. He almost threw it over my head. So, I was pretty impressed," Lilly said.
"It was awesome. I actually got to watch them get ready with the game," Dominic Diangi.
Before the game, the players signed a bat and gave it to Dominic.
