I'd only expect LA to get involved if Weaver's injury is serious. Should that happen, I could see Greinke traded for a package built around AAA pitcher Garret Richards and AA ss Jean Segura. I don't love either guy, but they're both top 100 prospects who are fairly close to the majors and it strikes me as a realistic return for half a season of Greinke. The Blue Jays weren't on your list, but a few weeks back Rosenthal mentioned them as a possible suitor for Garza or Greinke should either become available. An obvious target would be AAA ss Adeiny Hechavarria, though I wouldn't want him to be the centerpiece as most people seem skeptical of his bat. They're system is stacked, though, so finding a few other good pieces wouldn't be difficult. If they'd part with Jake Marisnick, I'd do cartwheels.
