In a post over the summer, I looked as to whether Joel Pineiro was getting lucky with his walks. His BB/9 at the time was astoundingly low (1.00), and I figured that it would go up based on his ball:strike ratio (it did, by 14%). This isn’t rocket science at all: Pineiro was maintaining a ridiculously low walk rate that resembled nothing of his skill set over his decently long career. However, it does let us look more closely at what I called EFF (for efficiency), which is basically how often a pitcher throws strikes relative to balls. So here are the 2009 Starting Pitcher leaders in the simple Strike %, which is simply just the percentage of strikes a pitcher throws out of all his pitches:
