Zack Greinke is officially available, and Jayson Stark has narrowed the list of serious suitors to just four teams:
But in reality, the market for Greinke appears to be narrowing itself primarily to four clubs: the Rangers, Angels, White Sox and Braves.
Teams that have spoken with the Red Sox, Blue Jays and Dodgers say they're not involved on Greinke, for various reasons. The Indians and Orioles are now all but out of the rent-a-pitcher business, unless the price tag is too cheap to turn down. And the Cardinals seem to be leaning that way as well.
My money's on the White Sox, for the simple reason that they're in the middle of the closest race for a division title; granted, that can easily change before the trade deadline. But as Stark notes, it might not make much sense to trade two good minor-league prospects simply to boost your chances of getting into that one-game Wild Card playoff.
