It's not exactly what you want to do when your team is down, but when a fly ball comes your way you have to try and catch it, right?

We have seen it happen before, but it's not usually by a visiting fan. However, this Boston fan wanted to try and impress the pretty lady in the Yankees jersey next to him, so he grabbed a home run ball.

One problem with that. The ball wasn't out of the field. So he basically pulled the ball into the stands to help his most hated rival go up 3-0. We are sure he wishes he chose the cheaper seats at this point.
