Yes, the sell highiest. The easiest way to identify buy low and sell high candidates among starting pitchers is to export the advanced tab of the leader board into Excel and then simply subtract the pitcher’s SIERA from his ERA. Sort and voilà, you now have your list of pitchers who are most outperforming and underperforming their SIERA marks. Of course, you shouldn’t blindly take that list as gospel, as some pitchers have proven that they can consistently post ERAs higher or lower than their SIERAs. But it’s the quickest way to generate a list of names for further analysis.
After performing this exercise, Matt Moore was not the biggest SIERA outperformer. But, given his name value and preseason draft cost, he is the one most worth shopping. He currently ranks eighth among all qualified starters in ERA outperformance, with a 4.11 SIERA versus a 2.29 ERA. While that alone should make him a sell high candidate, there are additional warning signs beneath the surface.
