I actually think Lorenzen is a pretty savvy option, but probably for another team. We already have enough "is he actually a starter?" SP candidates. Unless we're planning to do something fairly radical with the back end of the rotation (which I don't necessarily mind) I don't think we should be adding anymore unless it's a pre-FA guy with some minor league options remaining. On a completely different track, I've been thinking about this from Brett yesterday:
I've generally been ignoring this, wanting to add a Brad Miller or Kyle Seager for 1B/3B and call it a day. But like Brett says, Ian Happ is pretty much the only LH batter of consequence in the org above A Ball. And when you start trying to assemble prospective lineups, you can really feel the lack of a LH thumper. So a LH power hitter probably ought to be moved up quite a bit on the offseason priorities list. Corey Seager at SS would be the obvious ideal, but even Matt Olson or Michael Conforto would really scratch the itch. I also wonder about Joey Gallo. There's been a lot of smoke around him, though I don't know if it's real or if the fan base just hates him and is trying to speak a trade into existence.
