I'm having trouble understanding your first paragraph, is that talking about Zobrist or Reddick? More to the point, if they trade two outfielders then yes they'll probably want to add one. I'd put good odds against that happening though. Not sure what's difficult about it? It's clearly talking about both. The first half is talking about Zobrist, and the 2nd refers to the presence of Reddick making it feasible to give Ben days off. Of course, I wrote the sentence, so it could just be that what's clear to me isn't always clear to others. Believe me, wouldn't be the first time.
