When a baseball comes near the stands, people will give their best effort to grab it.
Check out the scene at Fenway Park when a foul ball rolled near the wall:
The man in the red jacket gave a strong effort and even needed the people around him to make sure he didn't fall out of the stands. Unfortunately for him, he couldn't find a way to get the ball.
It was a struggle for all of the fans involved, but one fan was rewarded for his effort.
