Norichika Aoki of the Milwaukee Brewers baseball team threw a ball into the stands where a young girl had been waiting eagerly in the hopes of grabbing a souvenir.
Just as she thought her dreams had come true, however, a grown-up with longer arms leapt in front of her and grabbed the ball.
Bemused, the girl went back to her seat with her mum, looking sullen-faced.
The good news for her, though, was that the television cameras had captured the entire incident.
The girl was tracked down in the crowd, and given the ball after all.
