I was doing 12U travel game(either last season or the one before that) I was the Field umpire its mid game a ball is lined into right and the right fielder catches it really low, I call it an out, the first base coach goes nuclear and yells "No Im appeling that!", points to the plate umpire who over ruled me calling the ball trapped, Is this appeal valid? the appeling coach was not the head coach and did not request the appeal thru me, the umpire with priority on the play
