Revised 2nd situation, check swing 4th out.

[BJ Moose]

OK Sam... got it now. Consider:

R2, R3. 2 outs. 2-2 pitch. CHECKED SWING, ball caught CLEANLY, and now catcher FIRES to third to attempt pick off. Ball sails into LF. R3 scores.. R2 rounds and comes home and is TAGGED out on a banger! 3 outs.

NOW....MAY defense appeal the checked swing call. (Batter practically screwed himself into the ground!)
