One time I was hit by a foul ball off of Sandy Alomar's bat, so I had to have been around 9 or 10.
Being that young and in shock from a foul ball hitting me (we were sitting down the first base line, so it came in fast), the ball dropped to the floor. Some fat lady next to me took the ball and told my dad she had to take it because she'd be letting her grandkids at home down if she didn't.
Her husband eventually bought me a hat because he felt bad, which I got signed by Miguel Olivo when we went to Grandstand after the game.
That's gonna make roster moves difficult.
