This paper will provide a general comparison of actual pennant winners and Pythagorean pennant winners for the National and American Leagues from 1901 to 2020. Instead of having multiple inputs to the Theorems formula to calculate a percentage, run differential is just a simple subtraction problem with one whole number that conveys the same meaning in a different way. 2021 Pythagorean wins: 7.98 (gap of 2.02) 2022 prediction: Decline Despite losing Adam Cerra, the Dockers are a sexy pick to jump into the top eight in 2022; but this stat sounds a word of warning.

This way we can have a better idea on what to expect for next season. Why cant we just use the points scored over total points as a basis for predicting the expected outcomes? Not surprisingly, teams that had a better actual won-lost record tended to do well in one-run games, and teams that had a better Pythagorean record tended not to do as well in such contests. 40 in 40 - 2021 Podcasts Minors & Prospects Coverage .

Current Major League Baseball Pythagorean expectation. Total Zone Rating and initial framework for Wins above Replacement calculations provided by Sean Smith.

In essence, a negative turnover ratio helps those sloppier teams with better expected wins as they punish the cleaner teams that had a high positive turnover margin with lower expected wins due to the luck factor that I have applied. where Win Ratio is the winning ratio generated by the formula.
