Well, what is "wrong" with Royals pitcher Zack Greinke?
Obviously there's been a drop in performance, but it isn't as if the dude has turned into Sidney Ponson. First of all, don't draw too much meaning from that 2-8 record. The Royals don't score many runs for Greinke; only 33 while he's been on the mound in his 15 starts. They've scored two runs or fewer in 9 of his 15 starts and have been shut out in 5 of the 15 starts. The run-scoring average of 3.09 for Greinke is the 4th-lowest in the AL. So of course he's going to be tagged with unfair "losses."
In short: The Royals don't score enough runs for him and his effectiveness is slightly down from last year.
I think Bernie Miklasz of the St. Louis Dispatch has a fair review of the Royals, particularly this part about Dayton Moore and the future of the Royals in 2010.
The Royals should be going all-in with young players and prospects but instead are playing and paying mediocre veterans and blocking the path of guys such as Alex Gordon, who was the No. 2 overall pick in the 2005 MLB draft. Gordon is hitting .333 / .457 / .577 with 10 homers at Class AAA Omaha. Why is he there? What's the point? Moore deserves credit for retooling the KC player-development system, which is showing signs of promise. But he's making the mistake of drafting good players and not taking the next step, which is to build around them.
