I guess it would depend on if there is a deep discount on their contracts or not. Are they going to go with the 14 pitchers/12 hitters again early on or was that just due to the lockout last season?
Diaz might make sense if they think they only want a SS for a really short time and then will pass him through waivers. Goodrum can actually hit, so is more likely to get claimed. I believe Diaz is a good fielder but it would be an upgrade if he was given a noodle bat. Honestly, I don't want them to call up Edwin at all, because there are far too many Edwin Diazes that have played professionally and it's a real pain to pull up his FanGraphs page.
