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. Perhaps winner of close games would have been more accurate, since Chicago scored more runs during the season than Cincinnati (806 versus 775).

Various terms, such as the Pythagorean Theorem of Baseball (used by Baseball-Reference.com) or the Pythagorean Expectation (used in the Wikipedia article), have been used to describe the formula developed by Bill James in his Baseball Abstract annual volumes to predict the number of games a team should have won in a season based on the numbers of runs scored and runs allowed.
