The Milwaukee Brewers are a few games below .500, it's early July, and Zack Greinke is set to be a free agent after the season. As much as the Brewers would like to get Greinke locked up to a long-term extension, it's possible they won't be able to do that, and so it's possible Greinke could end up on the trade market this month.
Should that happen, one potential destination would be Atlanta. The Braves are a few games over .500, and they've got talent to move. The Braves have already started scouting Greinke. And David O'Brien believes a match is realistic:
I still doubt #Braves would offer Greinke $20M per in long ext., but believe they're seriously considering trade even if re-sign not assured— David O'Brien (@ajcbraves) July 3, 2012
What O'Brien means is that he thinks the Braves might still try to trade for Greinke even if they can't get him signed to an extension right away. He lays out his thinking in a blog post. The Braves have young and talented arms to deal for an older and talented arm, and Greinke lives in Florida, which isn't far from Atlanta. The Braves have the players to swing a Greinke trade, and the circumstances are such that Greinke would probably consider sticking with the Braves for a while.
The Brewers won't trade Greinke today or tomorrow, and if they do decide to move him, there would be a handful of contenders. But you can put the Braves up there at the top of the list.
