The Cubs tracked down the young fan before he left the stadium and gave him a ball signed by infielder Javier Báez.
Another man who said he was sitting next to the fan who picked up the ball explained that the boy had "already had a ball" during the game. "Guy is A-OK so let it go people", Kaplan wrote.
Not to worry though: the team tweeted that the boy received not one but two baseballs used in the game.
The mother of the child who missed out on the ball in the video, also supported the man and released a statement through the Cubs, clearing him of any wrong doing.
According to Kaplan, the man had already helped the little boy get a ball earlier in the game.
At the end of the day, though, the kid went home with two happy hands.
"The whole world is calling this guy the most evil guy in the world for being a ball thief", he said.
A bystander close to the situation told the Chicago Tribune, the man in question didn't cheat the child out of the ball and took aim at online warriors for not knowing the full story.
