It's phony (ok, overblown) because a standalone baseball game is MUCH more left to chance than football and basketball.
Best part is, if you look at the >.500 standings, nobody is even good at it except for...the Brewers. They are 16 games over.
The Cubs, Dodgers and Phillies are a combined 4 over, and that's all Philly. The other 2 are .500.
What's more, most of these bad teams are something like 31-35 against >.500. They're beating them all the time.
