Rich Lederer has an excellent post breaking down MLB starting pitchers this season by strikeouts per 100 pitches, which is a nice way of correlating the ability to get strikeouts with pitch efficiency. You can really see what a great year Javier Vazquez is having, as well as one of the year’s most significant stories, the development of Justin Verlander. On the down side, Mike Pelfrey is way at the bottom of the list (of course, Pelfrey’s groundball tendencies mean he doesn’t need a great K rate to win, but he has to do better than this).
