That suggests that the biggest factor affecting pace is the pitcher. Pitchers can change catchers, teams or leagues; face a mix of batters; and pitch in front of a different defensive alignment or in different contexts. Yet their pace of play stays largely the same from season to season.
Not sure the purpose of measuring pace and this analysis. I would expect pitchers who pitch slowly will pitch slowly from year to year because that is their style. What is the point to this article?
I found there was essentially no correlation between pace and FIP or WPA.
Assuming FIP is a valid form of measurement he concludes that pace doesn’t even correlate to performance. Here is my disproof of the FIP formula.
