It was a horrible decision to go to third with 2 outs if it's even going to be close. Give the next guy a chance to drive you in from 2nd. If McKinstry can't score on a single to the outfield from 2nd, screw him. Just a low IQ play.
There isn't that much of an advantage being at 3rd over 2nd with 2 outs, at least not a big enough one to risk being thrown out
