I think this is a good deal for the Royals, though, and Moore should get credit for making his team better. . . Dayton Moore has made a lot of bad moves, but this is not one of them. He made his team better without spending significant resources to do so. Kudos to him for a nice signing.
Zack Greinke is about half way through the 2009 MLB season and to date he has been worth 5.5 wins. He is roughly on pace to accumulate 11 wins. As a pitcher. In the last four years, no pitcher has broken past the eight win mark. Since 2002, the first year our win values start, the highest recorded mark is Randy Johnson's 9.9 wins in 2004.... Greinke's batted balls are not significantly different from past years, but his home run rate has unsustainably dipped to just 3.3%. All in all, Greinke is missing more bats this year, but he is also throwing fewer strikes overall. Somehow he has reduced both his walks and his home runs allowed to depress his FIP to 1.98, but going forward you would expect that to be a lot closer to his 3.56 from last season. Still, with half a season banked, Greinke has a serious shot at being FanGraphs' first 10 win pitcher.
