In case you didn't notice the Fangraphs headline on the main page, Mat Klaasen concludes that Zito's current success is not sustainable. Not enough strikeouts; low BABIP; amazingly high rate of stranded runners if they reach.
Then there's my observation: Zito thrives when there's an extra day's rest between starts. When he's on a 5-day cycle repeatedly, his velocity goes down even more and he gets hit hard. Please join me in anti jinxing tonight, when he does have extra rest.
