It is really stressed in the world of umpiring not to hold grudges and while from my experiences I can't say it never happens it is pretty rare. I can see Fairchild having a short leash on Mes if a similar situation happens with Mes disputing a pitch. However as far as widening the zone when Mes is up or blowing a call against him, I seriously doubt that would happen. Most umpires especially at the professional level are not going to want to look bad by blowing a call just to settle a grudge. From my perspective and most of the umpires I know (including many ex pro's) , we realize that sometimes emotions can get out of hand because there is alot of intensity out there on the field and these things will happen.
One teachable moment from this whole thing is when confronting an umpire whether as a player or coach is to keep hands down or behind your back. I keep mine in my back pocket when confronted so they cannot accuse me of trying to hit them or accidentally bump them like what happened with Mes
