Interesting Play Last Night

[IREFU2]

I had an interesting event last night. There was a fast break and the player with the ball went up for a layup. Now the defender went up to block the ball and it was a clean block, but his hand was in the side of the offensive player and he clearly displace the shooter from my view. Of course the crowd went nuts when I called the foul. Its a good thing that I had a good look! Comments are welcome.
