It's funny because I thought about The Onion initially as well.Going to disagree some in that this may "seem" like a fun idea but should be an exhibition and not a real game. I thought this had to be some sort of Onion like joke when I saw it. Getting the field set up, even temporarily, as something fit for MLB is going to be a challenge. Temporary walls and all might be easier than getting the infield and outfield into shape.
The games in London, while fun and all in concept, where a joke. Glad that those games are unlikely to effect the race at this point but no one knew that when they were scheduled.
I read they are going to put together an 8,000 seat temporary stadium. I agree with the assessment about getting the field in proper shape for an MLB game and that it would better served as an exhibition.
