Re. a switchback: I think it can, because of an off-day to rest, reflect, and most importantly, reset... and relocate. Yup, the Sox just might be more focused at the task at hand behind enemy lines (if only they weren't so distracted by those twirling, orange hankies -- gimme a break, H-town, and mix in some real baseball fans).
5GGs new theory -- it's more likely for batters to get overanxious and roll over on outside junk when you're trying to be the home run hero for the hollering hometown crowd... instead of surviving via an adrenaline-induced laser focus, fighting for your lives in a hostile environment where you're outnumbered by tens of thousands of haters. Remember, if you're supposed to lose, then you've got nothing to lose -- and all it might take are a few elite athletes to channel the best hand-eye coordination in the world to stave off elimination.
