Reid Leonard Tables of October: Full Guide

Updated November 11, 2026

Reid Leonard’s “Tables of October” is a series of detailed statistical tables and accompanying commentary, published in the early 20th century, that catalog the results of Major League Baseball games played during the month of October, primarily focusing on the World Series and other late-season contests. These tables are notable for their meticulous, game-by-game documentation of scores, lineups, and pitching performances, serving as a valuable primary source for baseball historians and researchers.

Background and Historical Context

Reid Leonard was a baseball statistician and writer active during the 1910s and 1920s. He contributed to various baseball publications, including Baseball Magazine, and was known for his detailed statistical analyses. The “Tables of October” were compiled during a period when baseball statistics were not yet standardized, and box scores were often incomplete or inconsistent. Leonard’s work aimed to provide a reliable, comprehensive record of October games, which were then dominated by the World Series, a best-of-seven (or best-of-nine) championship series between the National League and American League champions.

The tables were published in a series of articles, likely in the 1910s and 1920s, and covered the World Series from its inception in 1903 through the then-current season. They were part of a broader movement among early baseball writers to create a more rigorous statistical foundation for the sport, predating the modern sabermetric era by decades.

What the Tables Contain

The “Tables of October” are essentially a season-by-season, game-by-game ledger of every World Series game played up to that point. Each entry typically includes:

  • The date and location of the game.
  • The teams involved and the final score.
  • The starting pitchers and their decisions (win/loss).
  • Key offensive performances, such as hits, runs, and runs batted in.
  • Occasional notes on notable plays or events.

For example, the table for the 1912 World Series between the Boston Red Sox and New York Giants would list all eight games (including the rain-shortened Game 2 and the decisive Game 8), with the score of each game, the winning and losing pitchers, and the series result. Leonard also included a summary table of cumulative team and player statistics for all October games, such as total hits, home runs, and batting averages.

How the Tables Were Compiled

Leonard compiled his tables from contemporary newspaper box scores, official league records, and his own correspondence with team officials and players. He was known for his meticulous cross-referencing: if a box score from one newspaper disagreed with another, he would seek a third source or contact the official scorer. This dedication to accuracy made his tables a trusted reference for other writers and for fans who wanted a definitive record of past series.

His methodology was unusual for the time because he treated October games as a distinct statistical category, separate from the regular season. This allowed him to analyze trends in championship play, such as the frequency of extra-inning games, the performance of rookie pitchers in high-pressure situations, and the impact of travel and weather on outcomes.

Significance and Legacy

The “Tables of October” are significant for several reasons:

  • They provide a complete, reliable record of early World Series games, many of which are not easily accessible in other sources.
  • They demonstrate an early attempt at systematic statistical analysis in baseball, predating the work of later pioneers like Henry Chadwick and Bill James.
  • They offer insight into how baseball was played and managed in the dead-ball era, including the strategies of legendary managers like John McGraw and Connie Mack.
  • They have been cited by modern baseball historians as a primary source for understanding the development of the World Series as an institution.

Today, the tables are primarily of historical interest, as modern databases like Baseball-Reference and Retrosheet have made such information freely available online. However, Leonard’s work remains a testament to the passion and rigor of early baseball statisticians.

Common Misconceptions

A common misconception is that the “Tables of October” refer to a specific book or a single publication. In reality, they were a series of articles published in Baseball Magazine and possibly other periodicals, each covering a different year or set of years. Another misconception is that Leonard invented the World Series statistics; he did not, but rather compiled and organized existing data. Finally, some fans mistakenly believe the tables include regular-season October games, which were rare in that era, but the focus was almost entirely on the World Series.

How to Access the Tables Today

Original copies of Baseball Magazine from the 1910s and 1920s are scarce, but many have been digitized by libraries and online archives. The most comprehensive collection is available through the Baseball Magazine archive at the Library of Congress, which offers free online access to scanned issues. Additionally, some issues are available on Internet Archive and Google Books. For researchers, the Society for American Baseball Research (SABR) has a research committee dedicated to early baseball statistics that may have compiled Leonard’s tables into a searchable database.

If you are looking for a specific year, it is best to search for the issue of Baseball Magazine that would have covered that year’s World Series. For example, the tables for the 1919 series (the infamous Black Sox scandal) would have appeared in an issue from late 1919 or early 1920.

Frequently Asked Questions

Are the Tables of October available online for free?

Yes, many issues of Baseball Magazine are available for free on the Library of Congress website and Internet Archive. However, the tables are not indexed by game or player, so you will need to browse the relevant issue to find them.

Did Reid Leonard cover the 1919 Black Sox Series?

Yes, the 1919 World Series between the Chicago White Sox and Cincinnati Reds would have been included in his tables, as it was the most recent series at the time. His tables would list the game scores and pitching decisions, but they would not include any commentary on the scandal, as it was not yet public knowledge.

What is the difference between the Tables of October and modern baseball databases?

Modern databases like Baseball-Reference are more comprehensive, covering every game in every season, and include advanced metrics like WAR and OPS+. The Tables of October are limited to October games, primarily the World Series, and use only basic statistics. However, they are valuable for historical context and for verifying data from the dead-ball era.

Why did Leonard focus only on October games?

October was the month of the World Series, which was the culmination of the baseball season and the most heavily covered event. By focusing on October, Leonard could provide a complete record of the most important games without the overwhelming volume of regular-season data.

Are there any errors in the Tables of October?

As with any pre-modern statistical compilation, there are occasional errors, usually due to conflicting box scores in contemporary newspapers. Leonard was careful, but not infallible. Modern researchers have cross-checked his tables against other sources and have found only minor discrepancies.
