RESEARCH: Pitcher-Positive Outcomes, pt. 2
Feb 20 2013
In our last R&A article, we looked at evidence for the sustainability of what we called “Pitcher-Positive Outcomes” (PPO).
We identified K% and Infield Flyballs (IFFB) as obvious PPOs because they result in essentially 100% out rates, and further, do not allow baserunners to advance.
Based on out rates for various trajectory/hardness of hit combinations, we added Medium-Hit Flyballs (MFBs) to the list of PPOs.
Then we looked at the overall correlations of these outcomes from one year to the next, and from two years to a third.
In the first phase of this study, it appeared these outcomes might indeed be at least partly repeatable. As a group, pitchers with elite PPOs in a given season showed a strong correlation with elite PPO...
