In his book The Baseball Economist, J.C. Bradbury titles a chapter, "How Good is Leo Mazzone?" Using statistical analysis, he analyzes whether Mazzone had a significant impact upon the pitchers that he coached. The sample is all pitchers who have pitched at least one year under Mazzone and one year under a different pitching coach. Bradbury found that Mazzone lowered the ERA of pitchers by an average of 0.64 points, and that after leaving Mazzone, pitchers' ERA increased by an average of 0.78 points. Bradbury believes that such an impact is deserving of Hall of Fame consideration.
