A Collection of Team-Season Statistics

John F. Jarvis

 


Using full season play-by-play descriptions, often called "events files", as the starting point, I have compiled a list of common and not so common statistics for individual teams. These tables are partial output from the analysis program I have written to process the play-by-play files. Much of this data was compiled both for input for a full season simulator and to compare with the simulator output. The seasons covered are for both leagues 1953 – 2008. Additional seasons will be added to these as I am able to obtain the play-by-play data. All the events files  are available from Retrosheet, Inc. Each of the season statistics pages contain 24 summary tables and is approximately 40 K bytes in length. A brief explanation of the contents of each table follows the list of available summaries.

The interleague summaries contain the interleague schedule, hitting for both leagues and a defensive pitching summary for both leagues. The pitching summaries include the interleague Win and Loss data for each team.

Special symbols used are defined in the data descriptions for the corresponding league summary tables.

Revisions: (December 13, 2008): Now AL and NL season data is now complete from 1954 to 2008. Please check the data descriptions for put outs and assists: putouts for catchers and assists for pitchers do not follow the offical scoring rules. See the Team Scoring Summary in the data description area for information about a data field tabulating the number of unknown plays.

With the exception of the schedule related tables, the data presented in the leaue season summaries is the same as for individual teams.

Important Note: The events files from Retrolist for 1973 and earlier seasons each have a few games coded using the Box Score Event File format. For these games, an extended boxscore is substituted for the standard play-by-play game data. The Retrosheet documentation lists the quantities available in these files. in general, game data dependent on context is missing in this format. Runner advances except the traditional SB and CS and events following IBBs are not tabulated in the BSEF data. The BSEF column in the Team Scoring Summary listing is the number of games using the BSEF data.

In the summaries I have attempted to preserve the accuracy of the play-by-play descriptions. Traditional statistics have been checked against published summaries. Fielding and some of the base running statistics are difficult to check, thus are possibly suspect. If you detect any systematic, not isolated or single, errors (please use the 1983 or 1996 seasons for this), inform me about them and please be sure to cite the source of data that you compared with my information. However, I do not warrant these files to be error free and I assume no liability for the consequences of any errors in the data.

A Brief Data Description

When ever possible, I have tried to use standard abbreviations. The non standard categories are defined below.

Team names are the Retrosheet/Baseball Workshop three character abbreviations. These are the first three characters of the team place name substituting an A or N as needed to indicate league when teams from the two leagues are in the same city. Two name places (San Diego) are given by the first letter of each name followed by A or N appropriate to their league.

Many of the tabulations also include league totals. Agreement between season totals for offensive and defensive quantities is expected. This is a measure of consistency in the program, not a guarantee of correctness. Following is a list of tables included with each league - season page.

Season Standings
Schedule - Games Played Between
Wins and losses vs. opponents
Team Scoring Summary
Team Offensive Hitting Summary
Team Defensive Hitting Summary
Situational Batting Averages
Lead Runner Advances on Singles and Doubles
Runner Advances on Singles/Man on Third, Double Plays
Fraction of On Base Runners Scoring
Team Sacrifice Summary
Offensive Teams Base Stealing Stats
Defensive Teams Base Stealing Stats
Team Defensive Pitching Summary
Team Errors Summary
Put Outs by Position
Assists by Position
Errors by Position
Runs per inning
Innings Scored in Distribution
Runs per game
Offensive LOB per Game
Number of Players Used in a Game Distribution
First PA post IBB PA summaries
To End of Inning post IBB PA summaries

Interleague results are summarized on the interleague pages for 1997 and newer seasons. All the quantities in these tables should be obvious.

Season Standings. The traditional ones: TEAM, Total games, G; as well as Won and Lost; Winning percentage, PCT; and Games behind, GB. Fractional games behind are expressed as a decimal fraction.

Schedule - Games Played Between: The number of games played against each opponent is given in a triangular table. This table is what is planned except in the strike shortened seasons or if a play-off game was necessary. In the 1967 tables KC1 is the Kansas City Athletics and WS2 is the Washington Senators. For 1997 and newer seasons interleague games are included in the win and loss totals for each team and the interleague schedule is part of the interleague stats page for each season.

Wins and losses vs. opponents: Read across the table for wins. Column "tot" is the team's total wins for the season. Read down for losses. The row "tot" is the team's total losses for the season. Interleague games are not included in this table.

Team Scoring Summary. RS/G and RA/G are team runs scored per game and runs allowed per game. SIGMA is the standard error for the team batting average (BA) using 70% confidence limits. SLG is the slugging average: total bases divided by at bats. A column has been added tabulating the number of unknown play types, UNKWN, found in the event files. Assists and putouts are primarily affected. BSEF is the number of games in the play-by-play files coded with the BSEF format.

Team Offensive Hitting Summary: LOB is runners left on base. HR4 is the number of grand slam home runs and IPHR is inside the park home runs. Treat the IPHR values with skepticism. HBYP is hit by pitch. TBB is total bases on balls including both the intentional and unintentional varieties. K are the strike outs made by the offensive team.

Team Defensive Hitting Summary. The same quantities as for the offense except these are the totals given up by the defense.

Situational Batting Averages: RS in this listing stands for "runner in scoring position" while HM and AW stand for home and away. DA and NI are for day and night games. SGNF is the probability that the null hypothesis is true: that is the differences could arise by chance. At the team level there is some support for a home and away effect but very little for better hitting with runner in scoring position and even less support for day/night differences.

Lead runner advances on singles and doubles: ON followed by the starting base for the runner, is the number of times the situation arose. Only the most common outcomes are tabulated. Runners occasionally score from first on a single (and are also thrown out trying to score). However, these do not occur sufficiently often to include them in the table. This is why the fractions don't add to 1.000 .

Runner advances on singles/man on third, double plays: As above, but with more than one man on base. Specifically, for singles, what happens to runners on first and second when there is also a runner on third. Advances on double plays are also listed.

Fraction of On Base Runners Scoring: The number of runners reaching each base and the fraction of runners reaching a base that score. Multiple base advances also reach intervening bases. That is, a home run counts for reaching bases 1, 2 and 3 on the way to home.

Team sacrifice summary: RAO is all non scoring runner advances on an out. SAC is the officially tabulated number of such advances. Similarly, RSO is all scores on an out and SFLY are the official run scoring sacrifice flies. ROH is the number of runners out, either the batter or an on base runner, following a hit. SHOP and SFOP are the number of sacrifice hit and sacrifice fly opportunities.

Offensive Team Base Stealing Stats: includes all double plays (DPL), not just grounded into types of plays, all triple plays (TPL), times picked off, PO#, stolen bases, SB#, made and times caught stealing, CS#. # represents the base stolen with 4 used for home. The percentage, %, is for all (2,3 and home) attempted steals. MAX/GM is the maximum number of stolen bases and caught stealing in a single game.

Defensive Teams Base Stealing Stats: Except for MAX/GM the numbers given up or made by the defense.

Team Defensive Pitching Summary: Much of the data traditionally kept on a team's pitching record is here. IP is innings pitched with fractional innings given as .1 or .2, RUNA is all runs allowed while ER is earned runs allowed. ERA is the team earned run average. OBA is Opponents Batting Average, K is strikeouts, CG is complete games, SHO is shutouts and SV is saves.

Errors: PB, BALK and WILDP are passed balls, balks and wild pitches respectively. ROE are fielding errors allowing the batter to advance to first. ERR/A are errors that allow base runners to advance. ERR/T is the sum of ROE and ERR/A. Allowed by the defense and received by the offense.

Putouts by Position: team putouts are tabulated by fielding position. Standard notation for fielding position is used. The Pitcher is 1 while the right fielder is 9. The putout, assist and error data in the following table are likely to be the least accurate of the quantities included in these tables.

Putouts for catchers does not include strikeouts. This is a purposeful deviation from the standard scoring rules.

Assists by Position: team assists are tabulated by fielding position. Analogous to putouts, pitcher assists from strikes outs are not included in the pitcher totals.

Errors by Position: Errors made at each fielding position. Pitcher and catcher totals include position specific errors: WILDP and BALK for the pitchers and PB (passed balls) for catchers.

Runs per Inning: The distribution of the number of times a given number of runs were scored in an inning are given. The column headings are the runs scored per inning. The entries in the table are the number of times that value was recorded.

Innings Scored in: The distribution the number of innings a team scored in a game.

Runs per Game: The distribution of the number of times a given number of runs were scored in a game is given. The column headings are the runs scored per game. The entries in the table are the number of times that value was recorded.

Offensive LOB per Game: The distribution of the number of times a given number of men were left on base while the team was batting.

Number of Players Used in a Game: The distribution of the total number of players appearing in a game. The column headings are the number of players. The entries are the number of times that value occurred. The effect of the designated hitter in the AL is interesting.

First PA post IBB PA summaries: A summary of the events occurring during the first plate appearance following an IBB.

To End of Inning post IBB PA summaries: A summary of events occurring after the first IBB in an inning to the end of the inning. RFIB is the number of runs scored in the inning following the first IBB.
