Posted April 29, 2022, reposted July 23rd 2022 In baseball, a run scored on offense carries the same on-field (win) value as does a run prevented on defense (e.g., according to both arithmetic and the highly-predictive Pythagorean expected .

These kinds of pitching statistics are solely individualistic and depend on the pitcher, not the team. The Yankees dominated the American League with 14 pennants in the 16 years from 1949 to 1964, but won only 11 Pythagorean pennants during those 16 years, with Boston (1949) and Chicago (1960 and 1964) also winning Pythagorean pennants.

Since in the quality model any constant factor in a quality measure eventually cancels, the quality measure is today better taken as simply the wins ratio itself, rather than half of it.] Furthermore, "[t]he Pythagorean projection is also still a valuable predictor of year-to-year improvement. In addition, to further filter out the distortions of luck, Sabermetricians can also calculate a team's expected runs scored and allowed via a runs created-type equation (the most accurate at the team level being Base Runs).
