missed tag play

[Blue19]

ok, points very well taken, thank you.

the only problem with the tag was that it was attempted to my right (the first base side) and the fielder of course was right behind the baserunner and the runner did a quick jump step and kind of arched forward to get out of the way so I'm not sure how i could see that tag/no tag. mechanics on where to position for that, especially coming from C position? as we very well know, fielders are prone to use those phantom tags.

in addition, please give me your input on whether or not I placed the runners on the right bases after the call reversal. b/c of the reversal, should the runners have gone back to 1st and 2nd b/c essentially I altered the play by calling the runner out, or b/c of the overthrow and BR going to 2nd, does that force R1 to 3rd after he gets put back to the bases?
thanks again
