I think it depends on what you think the umps should be doing. If they are there to call accurate balls and strikes, and any pitch that catches the edge of the zone is a strike, they didn't do a horrible job.
But if you expect an ump to establish "their" zone and stick with it, give a more lenient zone and calls to the better team and more experienced pitchers/batters (which is all totally bullcrap), then yes, they seriously screwed us.
The ump established a zone early on the game that was giving consistent strikes to outside pitches, and calling inside stuff that were strikes, balls. But in Gio's final inning, that suddenly changed and went back to a normal zone. The rest of the game then stuck that way.
If Kurt feels like they were getting outside calls from earlier, he keeps setting up outside to get the call, but it never comes.
I don't think we got screwed, but there could be a case to make. Just be sure to look beyond just Drew's 9th.
