And nobody on the team, coaching staff or otherwise, thought any different. They partied like they won something the night before, put in the B team lineup and pitching, and only really looked like they understood what was going on in the 7th inning.
PCA may have bailed them out, but there is a very real chance they don't advance (they need a result other than Mexico winning a low scoring game to advance), and at this point kind of deserve the embarrassment as a result of their ignorance and arrogance.
