Sit.
R3 on 1st 2 outs. B4 with a 0-2 count. R3 steals and is thrown out, B4 checks his/her swing. The catcher requests the plate umpire to go for help on the check swing because they do not want to pitch to B4 the next inning.

I believe that this does not fit into one of the reasons to qualify for a 4th out appeal in ASA. I would be interested in any other codes.
