This was a softball game and on the "fly ball", I called the runner out as the runner prevented F4 from catching the ball. On the "hit umpire", I stand corrected for FED rules as we were playing under them. One of the rule sets for softball stated that an umpire is to be considered as part of the ground. I do not remember which set it is/was as I have stopped doing any thing but ASA, baseball and high school. When you do different rule sets it is very easy to apply the wrong set during a game.
