U-11 association select ball. Bottom 2, R2 on second. Pitcher attempts to pick off the runner, who takes an awkward slide head-first into the bag. From my position, I'm completely shielded from seeing the swipe tag, which apparently was applied to R2's chest. I call R2 safe because I didn't see a tag. Head coach of the defense and his 3B coach in the dugout are immediately on me and asking to me to check the ruling with my partner. Of course, he can't see the play from where he's at. Call stands. 3B coach from dugout rattles on about how he saw the guy get tagged on the chest and all that. Eventually he gets quiet. Play continues. Top 3. On a caught swinging third strike, BR hits the caught ball out of the catcher's glove on his backswing and my partner rules a dropped third strike. BR is safe at 1st and R3 (who was on 3rd) scores. Defensive coach then asks my partner to get my help to see if there was backswing interference. After conferencing, we call interference on the batter, declare him out, and send R3 back to 3rd. During the conference, the offensive 3B coach is screaming at me and my partner about how he wants time it back on the clock (these games are timed) because of our conference. I poke my head out of my discussion to tell him that we don't stop the game clock for appeals, etc. He gets quiet, only to rip on us again when we affirm the call of interference. I let him say his piece, didn't respond because nothing he said was profane or personal. Bottom 4, 2 outs, offensive (home) team is losing. Time has expired so this is the last inning. R2 once again at 2nd. Pitcher does a pitchout and the catcher guns the ball down to 3rd basebfor a bang-bang play. I call R2 out on the tag. Immediately, the head coach, R2, and that same 3B coach are all screaming at me again. But the 3B coach decides to tell me that I suck and that I'm incompetent. Sure the game was over, but I chucked him out anyways.
