First year umpire and poster. Had a 5 and 6 year old coach pitch/T-ball game this evening. R1, grounder to F4, I clear the plate and face the ball as the coach/pitcher is coming off the field and turns to me and says 'He can't do that, F3 ran into him. I never saw it, and as I looked in that direction, still couldn't see F3, R1, or BR, as coach is directly in my line of sight, and about 2 feet from me. F4 tags second. I call him out, as I never saw the obstruction, though it's fairly logical to conclude that it happened, as R1 was just standing there crying his eyes out.
Question is, can/do you ever call what you didn't see? How would you have handled it?
