Well, DiMuro had 2 problems:
- He was moving (as was previously stated) when he should have been set to see the catch
- He got straight lined by the guy in the green shirt who pointed at the guy with the ball.
There is no way DiMuro could have seen the ball fall out of the glove with that guy in the way.
All of that said, I love the way amateur umpires take pleasure in berating a professional umpire. Maybe it's because DiMuro made it and you didn't? Or maybe you think that you can do better? Be careful how you answer that because when you look in the mirror, you see an AMATEUR staring back at you..... because that is what you are! Try and remember that!
