Over at The Baseball Analysts, Chris Moore has a very interesting piece about which pitchers have the best fastballs in the game today. The premise is classic process-centric thinking: filter out the luck aspect of pitch outcomes, and instead focus on the quality of the pitch irrespective of results. To this end, he uses a complex method to assign an expected value to each fastball thrown based on its PITCHf/x data (velocity, location, movement, etc.), and see who averages the fewest "expected runs allowed" per fastball thrown. And the winner? Well, you'll have to read to find out, but let's just say that he's having one of the 30 best ERA+ seasons of all-time this year.
