And the Cincinnati Reds, who won one actual pennant in the 1960s (1961) won two subsequent Pythagorean pennants (1964 and 1965).

They actually deserved one more win, according to their Pythagorean record, and as we mentioned above, San Diego's +84 run differential was the second . Become a Stathead & surf this site ad-free. Even though the Pythagorean predictions are usually highly accurate, the closeness of many pennant races, with the winning margin often being no more than three games, means that there have been many pennant races in which the actual winner and the Pythagorean winner have been different. Out of my 71 different correlations, the highest ranked pitch type or velocity statistic was cutter percentage at 41st with a p-value of 0.137. A team has 570 runs scored compared with 556 runs allowed.Pythagorean Win = 1 / (1 + (556 / 570)2)Pythagorean Win = 1 / (1 + (0.975)2)Pythagorean Win = 1 / (1 + 0.95)Pythagorean Win = 1 / 1.95Pythagorean Win = 0.512This teams Pythagorean win is 0.512 using run data, it is expected that this teams win-loss percentage should be 51.2%.

Check out the Major League Baseball Detailed Standings including East, Central and West Division Stats on Baseball-Reference.com . Another noted basketball statistician, John Hollinger, uses a similar Pythagorean formula, except with 16.5 as the exponent. General manager Jerry Dipoto and the rest of the Mariners front office clearly agreed. These formulas result in the team's expected number of runs given their offensive and defensive stats (total singles, doubles, walks, etc. Whisnant: Beyond Pythagorean Expectation: How Run Distributions Affect Win Percentage Direct from the 2010 MIT Sloan Sports Analytics Conference (AKA - Dorkapalooza) comes The Pythagorean expectation formula, originally developed by Bill James, provides a reasonably good estimate of the win percentage of a baseball team using the number of . The fact that the most accurate (constant) Pythagorean exponent for baseball is around 1.83, slightly less than 2, can be explained by the fact that there is (apparently) slightly more chance in baseball than would allow teams to win in precise proportion to their quality. This is why we can use a Pythagorean win total compilation to compare what was expected to happen based on points scored for all of the NFL teams, to what actually did happen in how these teams finished out their year. But this is a two-stage process. The same relationship is true for any number of runs scored and allowed, as can be seen by writing the "quality" probability as [50/40] / [ 50/40+40/50], and clearing fractions. This is because a season (with only 162 games) does not provide a large enough sample size to conclude that a team is the best team in its league unless it wins 18 or more games than any of its opponents. One thing that I found that we can somewhat account for is turnovers. There are occasional outliers, illustrated here by Cincinnati in 1961, which won 10 more games than its Pythagorean prediction. Basketball's higher exponent of around 14 (see below) is due to the smaller role that chance plays in basketball. Among the many cases of teams winning the Pythagorean pennant, but not the actual pennant, are the Chicago Cubs (1969 and 1970) and the Seattle Mariners (2001 and 2003).

Please see the figure. You can't predict baseball, but it's that time of year to start trying to do it anyway. But the 2021 Twins are running out of time and chances .

It is my guess that it would still be the case that only a small proportion of the seasons with different actual and Pythagorean pennant winners would differ by one standard deviation or more in their records and that seasons with differences of two standard deviations or more would be extremely rare (perhaps just the 1987 American League). Pythagorean Expectation is a metric that evaluates a teams number of runs for and runs against and attempts to use that data to come up with what a teams win percentage should be base on run data alone.It is assumed that over a longerperiod of time (for example a baseball season), win/loss percentage should correlate with run data based on the Pythagorean expectation formula.Pythagorean expectation can be used to determine if a team is ahead or behind where it should be based on run data. The method that we will be discussing today is the 2021 Pythagorean win total calculation as a method to help predict the 2022 football season results. Wikipedia - Pythagorean Expectation - An entry on the concept of Pythagorean . Various candidates for that constant can be tried to see what gives a "best fit" to real life data. In addition, the formula tends to regress toward the mean, as teams that win a lot of games tend to be underrepresented by the formula (meaning they "should" have won fewer games), and teams that lose a lot of games tend to be overrepresented (they "should" have won more). Cincinnatis nicknamethe Big Red Machinegained prominence in 1970 when the team won 70 of its first 100 games. Think of points scored as (a), and points allowed as (b) where (c) is a function of the (a and b) linear equation and we just want to know what the relationship is between a^2/c^2 (c^2 is a^2 + b^2)to get a percentage of wins multiplied by the total games. For example, as R/OR increases from 1.0 to 1.1, predicted WP increases from .500 to .543, or by .043; and as R/OR increases from 1.7 to 1.8, predicted WP increases from .725 to .746, or by .021.

Rounding one standard deviation to the nearest whole number (six) means that an average teams record would range from about 7587 to about 8775 about 68 percent of the time (reflecting the proportion of the area under a bell-shaped curve within one standard deviation of the mean). His initial equation was: Over the years this has held up with slight changes in the exponent to get a higher correlation between expected wins and actual wins. This means that the Red Sox are statistically expected to be 50-37, four games worse than their actual 54-33 record.
