The win probability for a specific situation in baseball (including the inning, number of outs, men on base, and score) is obtained by first finding all the teams that have encountered this situation. Then the winning percentage of these teams in these situations is found. This probability figure is then adjusted for home-field advantage. Thus ...

American football win probability estimates often include whether a team is home or away, the down and distance, score difference, time remaining, and field position. American football has many more ...
Pythagorean expectation is a sports analytics formula devised by Bill James to estimate the percentage of games a baseball team "should" have won based on the number of runs they scored and allowed. Comparing a team's actual and Pythagorean winning percentage can be used to make predictions and evaluate which teams are over-performing and under ...
In baseball statistics, slugging percentage (SLG) is a measure of the batting productivity of a hitter. It is calculated as total bases divided by at-bats , through the following formula, where AB is the number of at-bats for a given player, and 1B , 2B , 3B , and HR are the number of singles , doubles , triples , and home runs , respectively:
James has noted that there are cases in which his original version of game score does not accurately reflect a pitcher's performance.
