A couple of questions to follow-up from the most recent post…..

Proportion of pitchers WITHOUT “signature” pitches, but have below-average pitch grades that perform well

For clarity, the sample of pitchers in each row DO NOT meet the criteria outlined in the first column.

In summary - Pitchers WITH “signature” pitches have roughly 10-13% more members of their population outperform below-average pitch grades

Year one to year two improvements

Looking at pitchers who improved a below-average pitch grade to a “signature” pitch from one year to the next, and how many of their below-average pitches improved from a below-average RV/100 to above-average in the same two year stretch.

This criteria might be too specific for only looking at 2021-2023, but interesting to note that it does not happen frequently.

Out of 721 pitchers in the sample…

Each row represents a different signature criteria, with the number of pitchers meeting that criteria and the number of pitchers among them who saw improvements in performance for all of their below-average pitches from year one to year two.
