Sabermetrics

The term Sabermetrics stands for analysis in baseball through objective evidence, especially by statistics. The term derives from SABR from ( Society for American Baseball Research), an association that deals with the scientific study of the baseball sport. The term Sabermetrics was coined by Bill James, who has been working as one of the first with statistical analyzes and since then, in addition to Nate Silver one of the most famous advocate of Sabermetrics.

Principle

The Basics of Sabermetrics it, the content and validity of statistics to critically to decide to what extent they are at all useful for the analysis part. For classical statistics such as batting average, RBIs and pitcher wins are regarded as of little use, because they either

  • Only one aspect of a player's performance look ( example: the batting average does not account for extra - base hits or walks ),
  • Poorly correlated with the runs scored ( Example: The batting average correlates significantly worse than, say, the on- base percentage ) or
  • Individual and team performance mix (example: RBIs and wins can not be achieved by one player alone).

Even tactical elements of the game such as Base Stealing or Bunts are considered critical because statistical analyzes have shown that these have no positive benefit in many cases. Due to the critical questioning of established methods and tactics that are partially accepted for over a hundred years, Sabermetrics is strongly criticized by some baseball traditionalists, but that the methodologies or statistical basis be refuted without.

Among the most important methods of Sabermetrics include:

  • Development of statistics that correlate as closely as possible with the number of votes gained or Runs
  • Development of statistics, which cover the whole of a player's performance and not only some aspects
  • Analysis of statistics by considering all such period or stadium influences

Sabermetrics in Germany

For the German Baseball and Softball sports, there are almost no publications on Sabermetrics, apart from a few entries on websites, blogs or discussion forums. However, the statistics for the federal and regional leagues of the German Baseball and Softball Federation in recent years have been continuously expanded and modern statistics like OPS and Range Factors are already available. An important step for improved analysis was the introduction of advanced defensive statistics for the federal and regional leagues in the years 2008 and 2009. Separating the defensive stats by positions and the identification of defensive innings Played was the significance of the defensive statistics significantly increased. With the introduction of the new DBV -Score Sheets 2009 Doubles, Triples, Sacrifice Hits Sacrifice Flies and were also introduced as an additional Pitcherstatistiken, so that now Opponents ' OBP and Opponents ' SLG can be calculated.

To be in the offensive, defensive and Pitchingbereich sufficient data for Sabermetrics analyzes, even if the available material can not long keep up with the data available for the Major League Baseball. Detailed Situational Stats and Play-by -play data there will be no long term due to the amateur status of the German Baseball sport and mostly volunteer data entry.

First would have to be clarified whether the established Sabermetrics statistics are applicable to the German Baseball. While running the game by the same rules as such in Major League Baseball, but there are differences due to the lower levels of the tournament schedule. In the German Baseball example, there are significantly more walks, hit -by- pitches, Stolen Bases, errors, wild pitches and Passed Balls as in the MLB, but less extra - base hits, and definitely less homeruns. The production of runs is so different and this affects probably due to the accuracy of Runschätzverfahren from. Initial analyzes have shown that the normal Runs Created formula estimates the runs in the German Bundesliga clearly too low.
