Answer
I've got a runner on first with two outs.  Next batter.  Pitcher gets credited with strike out and a wild pitch!  
 
I know this is a problem somewhere and a coach will be ticked no matter what the call.

My first thought was the way I called it but then thought about the opportunity lost by the defense and became unsure.  I called he ASA district UIC and he agreed.
