From the perspective of this one player\coach...
I wouldn't argue that call. If you can get a runner out by hitting them with your elbow, why not your shoulder, or your butt, or your foot? where does it end? Slippery slope there. Tag with leather or with the ball. Totally agree.
Of course, then it gets into the "What you saw wasn't what I saw argument" Dave mentioned earlier. And then you guys are the official enforcers of the rules on the field and you call what you call.
Hah, I just wish you guys would admit a mistake every once in a while.
Had a lady ump in our tournament last year. I was playing 1B. shortstop turns a double play (by a good two steps literally) with 1 out and starts running off the field, along with all 12 other guys on the field (including base coaches and the two runners.)
She calls the guy safe at first, to the astonishment of everyone on the field, and the crowd on the first base side of the field.
She later admits to my catcher that she was in a bad position, didn't see it, and blew the call.
Why not just admit it when the bad call is made and fix it?
(That's pretty much a rhetorical question. I know you guys can't really speak for anyone other than yourself
)
