The Royals are expected to listen to offers for right-hander Zack Greinke this winter and into next summer. Kansas City would probably be able to get a nice haul of prospects for Greinke, players that would be ready to blossom in the coming years. ESPN's Buster Olney says that the Royals do see value in keeping Greinke, but they may benefit over the long-term by trading him.
