The current winning atmosphere in Boston will probably be too intimidating for A-Rod, who really likes to hit solo homers when his team is down or up by seven or so runs, preferably in meaningless games.
I'm betting he goes to Wrigley, and back to Piniella, his old Seattle manager. (I would give up a pinkie to have Lou back in the Bronx.) The Cubs have just the right blow-the-big-game tradition and a stadium that should guarantee 75 homers.
Boston would obviously be the best option for theatrical purposes.
