The most eye-popping scene in that movie is when he tracks down "Coop" who he told his son over and over again was the best player he ever played with (implying he played college or minor league ball).
So he takes his jacket off and is decked out in Bobby Rayburn's complete game uniform and pitches to BobbAY's kid with Coop catching.
Coop helps the kid escape and DeNiro proceeds to beat his arse with a baseball bat, asking him why he did that.
Then it finally comes out when Coop says "that was little league when we were 11" and you're like "whoa" if he wasn't insane before, he sure is now.
