While the reigning Cy Young doesn't have many wins, he does still have great numbers. But, for now, so do several others. And some have better. One contender recently dropped out after a season ending injury. Another candidate could be shut down in August if everyone sticks to their "guns".
Even though I'm not listing them, props to Chris Capuano's great start. And AJ Burnett's return. And Lance Lynn making people forget Jaime Garcia forgot to show up this season.
