I would do that in a heartbeat. It's a minor impact to the current major league team and only includes one pitcher (and Ortiz would be my choice to trade). You're selling high on Harrison, which I think they should do, since OF is a position of depth within the organization. With Diaz, you're betting that Hiura is the long term answer at 2B - he and Diaz very likely won't both be on the major league team, and while it would be nice to let it play out to see which one develops better, if you can parlay one into Archer now, do it.
