Zack Greinke had his resurgence after battling anxiety issues framed as a small-market triumph in 2009, as he posted a 2.16 ERA for the Royals and was named the AL Cy Young winner. Now, he'll be tasked with propping up another small market rotation.
For the Brewers, swapping prospects and young talent for an top-notch pitcher definitely seems like a push to contend in 2011. It will be Prince Fielder's last season in Milwaukee, in all likelihood, and Greinke arguably becomes the best pitcher in the NL Central — at worst, he's in the top three with Adam Wainwright and Chris Carpenter of the Cardinals — as the Brewers' staff ace.
For the Royals, though, the deal seems more like giving away a cherished player for a chance at reloading in a few years. Our Royals Review doesn't like the deal, and thinks general manager Dayton Moore is filling needs rather than maximizing return.
