They did the right thing
I don't get through Chicago very often but was there yesterday. Cold weather doesn't bother me too much so I was prepared to buy a warm hat and gloves and head down with an almost-free ticket from StubHub. But that's my choice - the vendors, ushers etc. wouldn't have that choice. Plus, season ticket holders and those with tickets purchased at face value would have needed to suck it up or eat their tickets.
There are five months to get this game played, CWS management did the right thing.
