Chicago Cubs owner Thomas Ricketts is used to getting an earful from fans about his baseball team ... but now he's even drawing the ire of LITTLE KIDS -- 'cause a six-year-old child called him cheap straight to his face!
TMZ Sports obtained the hilarious clip shot last weekend at the team's annual fan summit called "Cubs Convention." In the clip, Ricketts, owner and team chairman, was making the rounds signing autographs and chatting it up with supporters ... when he encountered the disgruntled young boy.
We're told the plan was for the kid to ask Ricketts to sign a bat inscribed with "The cheapest owner in Baseball" .
