I say again, NOOOOOOOOOOOOO. Basically you'd "have" to relegate him to 7th by that thinking. Like I said before, I'd rather Castro sees the type of pitches that a #2 hitter is going to see as opposed to a #7 hitter hitting in front of the monstrosity at 2B and then the pitcher. The Cubs are a team in transition (though yes, it's a shitty division, but let's think big picture) and I'd rather that someone ideally as important to the Cubs' future as Castro go through his growing pains in the hitting spot that ideally he will be in for a long, long time (and where he'll get more PA) than facing the garbage that can be thrown at the #7 hitter in this lineup. Hell, I think he'd actually see better pitches as the #8 hitter in front of the pitcher than #7. And I'm assuming you'd want Soto at #2 instead of Castro, right? Who else on the team (discounting Fukudome assuming he's going to be leading off consistently) is going to so significantly outperform Castro in regards to OBP? There's Aramis, but I'm guessing you want him sticking at #4.
