According to Jon Paul Morosi of FOXSports.com, the answer to that question is yes.
The market for outfielder David DeJesus will be robust, as long as the Royals ask for a reasonable return. The Red Sox and Giants are among the interested parties. Infielder Alberto Callaspo could be moved, too. There is no indication at this point that ace Zack Greinke will be available; Greinke isn't eligible for free agency until after the 2012 season, but his salary will increase to $13.5 million next year.
I can't envision a scenario in which Greinke becomes available. If the Royals price on DeJesus is high, it would be astronomical on Greinke so don't expect him to go anywhere.
