The Dave Duncan Effect

Last week Dave, in his piece on Real Groundball Rates, and Erik, in a piece on Brad Penny’s first start, referenced Dave Duncan’s ability to get his pitchers to generate a great deal of groundball outs. In fact in Dave’s summary of the Cardinal’s organizational ranking he specifically referenced Duncan’s ability to take pitchers off of the scrap heap and turn them into serviceable MLB starters with his pitch to contact philosophy, and cited it as one of the reasons for the Cardinals recent success. With all of that in mind I thought it would be interesting to investigate how the batted ball data supports these positions, and what is the magnitude of the effect.
