Standings tables have columns for Team ID, Wins, Loss, BAT, PITCH, and UR. Each of these columns will be described in more detail here. There is a standings view for every year and every game day from 1903-present.

There are 30 unique Team IDs in this model and much like airports, each a 3 character code representing a modern franchise and its history. This code travels back in time so the Brooklyn Dodgers will be labeled LAN pre 1957 and the Brooklyn Robins pre 1932. The New York Giants are labeled SFN and so on. This goes for all franchises.

Team ID links in the Tm column lead to the team status view for that team on that day or that year. They are ordered by best WAA in each league or division depending upon year.

The W and L columns are simply Wins and Losses on that day or end of year. WAA = W – L

Team Runs Scored is a team hitters or BAT stat. The BAT column shows how much above or below league average for runs scored.

League average for runs scored is equal to league average for runs scored against which is a team pitchers or PITCH stat. The PITCH column show how much above or below league average according to the following:

PITCH = R{team league average) – R(scored against) – UR.

The UR column shows team Unearned Runs above or below team league average. A positive sign means a team gave up fewer than league average, negative they gave up more. Unearned Runs are not counted against a pitcher so they are subtracted from the PITCH column above.

BAT, PITCH, and UR columns provide a high level view of where a team’s strengths and weaknesses lie. These however are seasonal stats. The state of a team on a daily basis lies in the strength of their roster on that day.

Run differential is team Runs scored minus Runs against and used in Pythagoean Expectation to estimate a win/loss record or team WAA.
